How to Get rid of Silverfish?

How to Get Rid of Silverfish

To get rid of silverfish, use moisture control, crack sealing, food-source removal, Diatomaceous Earth, sticky traps, natural repellents, and chemical treatments to reduce active infestations. For severe or recurring problems, Contact a pest control expert, as it can hide in wall voids, basements, attics, bathrooms, closets, and other damp indoor areas.

Successful silverfish management also relies on thorough cleaning and safeguarding key areas such as bathrooms, bedrooms, attics, basements, carpets, closets, kitchens, bookshelves, garages, condos, and apartments. Lowering humidity, fixing leaks, storing dry goods in airtight containers, decluttering cardboard, vacuuming hidden spots, and sealing potential entry points make indoor environments less hospitable for feeding, hiding, and breeding.

Avoiding future silverfish infestations depends on ongoing moisture regulation, proper storage, cleanliness, and monitoring. Keeping humidity under control, drying wet surfaces promptly, eliminating paper clutter, protecting fabrics and books, using traps in active zones, and checking for droppings, shed skins, stains, or chewed items helps reduce the likelihood of these pests returning indoors.

8 ways to get rid of silverfish are:  

  • Reduce Moisture Levels in Damp Areas: Lowers indoor humidity and removes excess moisture that silverfish need to survive, breed, and remain active indoors.
  • Seal Cracks, Gaps, and Entry Points to Block Silverfish Access: Blocks hidden entry routes and harbourage areas that allow these insects to enter, spread, and hide throughout the home.
  • Remove and Store Food Sources Properly: Eliminates access to starches, paper materials, food residue, and organic debris that support silverfish feeding activity.
  • Use Diatomaceous Earth as a Natural Silverfish Killer: Dehydrates silverfish naturally by damaging their exoskeleton after contact with food-grade Diatomaceous Earth.
  • Set Sticky Traps in High Activity Areas: Captures active silverfish, helps identify infestation hotspots, and monitors population levels over time.
  • Use Natural Repellents Like Cedar and Essential Oils: Discourages silverfish activity by making closets, storage spaces, and damp hiding areas less attractive.
  • Use Chemical Silverfish Control Products: Reduces hidden silverfish populations through targeted use of boric acid baits, insecticidal dusts, and residual treatments.
  • Call a Pest Control Expert for Severe or Persistent Infestations: Provides professional treatment for widespread, recurring, or difficult-to-reach silverfish infestations.

Reduce Moisture Levels in Damp Areas

Reduce indoor humidity to below 50% to eliminate silverfish, as they thrive in dark, humid environments with moisture levels between 75% and 95%. It depends on damp air, condensation, and hidden moisture sources to survive and reproduce inside bathrooms, basements, attics, crawl spaces, and storage areas. Dry indoor conditions disrupt the activity, limit breeding, and make infestations harder to sustain over time.

Methods to reduce moisture levels in damp areas include:

  • Run dehumidifiers in moisture-prone rooms: Place them in basements, attics, crawl spaces, and laundry rooms to reduce excess humidity and keep indoor air sufficiently dry to discourage silverfish activity.
  • Use bathroom exhaust fans during and after showers: Turn on exhaust fans while showering and keep them running for at least 20 minutes afterward to remove humid air and reduce condensation on walls, ceilings, and baseboards.
  • Inspect and repair leaking pipes immediately: Check under sinks, behind appliances, and around plumbing lines for hidden leaks, as constant moisture buildup often attracts silverfish into cracks and gaps in walls.
  • Place moisture absorbers in enclosed storage spaces: Use silica gel packs or moisture absorbers inside closets, pantries, and under sinks to reduce trapped humidity in dark storage areas.
  • Dry wet surfaces and remove damp materials: Wipe sinks, floors, countertops, and tubs regularly, then replace damp cardboard boxes or wet paper storage, as silverfish remain active longer in moist environments with water-damaged materials.

Seal Cracks, Gaps, and Entry Points to Block Silverfish Access

Block cracks, gaps, and hidden openings to prevent silverfish from entering damp areas and spreading throughout the home. Silverfish have flat bodies that allow them to squeeze through tiny crevices around baseboards, pipes, windows, doors, and wall gaps. Sealing these openings helps reduce the activity in bathrooms, basements, attics, crawl spaces, and other humid areas.

Simple methods to block silverfish entry points include:

  • Apply silicone caulk around wall edges and trim: Seal gaps along baseboards, crown molding, wall corners, and floor trim with high-quality caulk, as silverfish commonly travel through narrow structural cracks.
  • Fill plumbing and utility openings with foam sealant: Use expanding foam sealants such as Great Stuff Pestblock around plumbing pipes, electrical conduits, and utility line gaps under sinks or behind appliances to create a moisture-resistant barrier.
  • Pack larger cracks with steel wool or copper mesh: Insert steel wool or copper mesh into deeper wall gaps, foundation cracks, or pipe openings before sealing to block hidden silverfish pathways more effectively.
  • Replace worn weatherstripping around exterior doors: Install tight weatherstripping around doors to close side and bottom gaps that allow silverfish to enter indoors.
  • Seal window frames and exterior cracks carefully: Apply waterproof caulk around window sills, exterior trim, and small structural cracks to reduce moisture intrusion and block outdoor access.
  • Inspect damp areas regularly for new gaps: Check bathrooms, basements, attics, crawl spaces, and laundry rooms for moisture-damaged openings, as silverfish often spread through dark, humid spaces.

Remove and Store Food Sources Properly

Remove accessible food sources and properly organize stored materials to make kitchens, pantries, attics, and closets less attractive to silverfish. These insects feed on starch-based materials and organic residue such as flour, cereals, sugar, pet food, paper, cardboard, wallpaper glue, and book-binding adhesives. Crumbs, paper dust, and damp storage materials allow silverfish to survive in dark, humid spaces.

Follow these ways to remove and store food sources properly:

  • Store dry foods in airtight containers: Transfer flour, cereal, grains, sugar, snacks, and pet food into sealed glass or hard-plastic containers, since silverfish can easily enter cardboard packaging.
  • Vacuum pantry shelves and kitchen edges regularly: Clean pantry corners, cabinet edges, baseboards, and kitchen floors to remove crumbs, starch particles, paper dust, and food residue that attract silverfish feeding activity.
  • Keep produce areas dry and clean: Refrigerate ripe fruits when possible, wipe up sticky spills immediately, and clean fruit bowls regularly, as moisture and organic buildup can attract silverfish.
  • Replace cardboard storage with sealed plastic bins: Store books, magazines, newspapers, and paper items inside airtight containers because silverfish insects feed on cellulose fibres, paper starches, and glue-based materials.
  • Reduce clutter in storage areas: Remove damp cardboard boxes, wallpaper scraps, and unused paper bags from attics, closets, and basements, as cluttered spaces often harbour silverfish populations.
  • Clean pet feeding areas daily: Sweep around pet bowls and regularly remove leftover dry food to reduce crumbs and organic debris in kitchens and laundry rooms.

Use Diatomaceous Earth as a Natural Silverfish Killer

Apply food-grade diatomaceous earth in dry hiding areas to kill silverfish naturally by damaging their outer exoskeleton and causing dehydration. Diatomaceous earth works mechanically rather than chemically, making it an effective natural treatment for bathrooms, basements, attics, crawl spaces, and storage areas. Silverfish insects only need to crawl through a thin layer of the powder for the treatment to work effectively.

Effective practices to use diatomaceous earth for silverfish control include:

  • Choose food-grade diatomaceous earth only: Buy food-grade diatomaceous earth rather than pool-grade products, as it is safer for indoor use around pets and living spaces.
  • Target dark, humid hiding spots: Apply the powder behind baseboards, in wall cracks, under sinks, behind appliances, and around attics or crawl spaces where silverfish commonly hide.
  • Spread a thin, light dusting: Use a hand duster or spoon to apply a fine layer, similar to flour, because silverfish avoid thick, visible piles of powder.
  • Keep treated areas completely dry: Repair leaks, reduce humidity, and prevent condensation, as moisture quickly reduces the effectiveness of diatomaceous earth.
  • Leave the powder undisturbed for 24 to 72 hours: Allow enough contact time for silverfish insects to crawl through the treatment and dehydrate before vacuuming the remaining powder.
  • Wear a dust mask during application: Protect your nose and lungs from airborne particles while applying the powder inside enclosed or poorly ventilated spaces. ccessible food, hidden hiding spots, and secure breeding environments commonly found in bathrooms, kitchens, basements, attics, closets, and storage spaces.

Set Sticky Traps in High Activity Areas

Place sticky traps in high-activity areas to capture silverfish, monitor infestation zones, and reduce indoor populations. Sticky traps work best along baseboards, near plumbing fixtures, in pantry corners, and around damp storage spaces where they often travel. Combine traps with moisture control and food source removal for better long-term silverfish control.

Key ways to use sticky traps for silverfish control include:

  • Place commercial sticky traps near travel paths: Position BioCare Spider and Silverfish Traps or EcoPest traps along baseboards, behind toilets, under sinks, inside cabinets, and near plumbing lines where they remain active at night.
  • Use cardboard and duct tape traps indoors: Wrap duct tape around cardboard with the sticky side exposed, then place it in closets, basements, pantry corners, or under appliances to trap moving silverfish.
  • Set glass jar traps with starch-based bait: Add small amounts of flour, cereal, or bread inside a glass jar, then coat the inner rim with petroleum jelly to trap silverfish searching for food.
  • Target dark, humid spaces carefully: Place traps in bathrooms, attics, crawl spaces, laundry rooms, and storage areas, as silverfish prefer damp, undisturbed environments.
  • Replace traps every few days: Remove full or dusty traps regularly because fresh adhesive surfaces improve silverfish capture rates and help monitor ongoing activity.

Use Natural Repellents Like Cedar and Essential Oils

 

Apply cedar and essential oils around dark, humid areas to naturally repel silverfish and disrupt their hiding and breeding indoors. Place cedar, peppermint, lavender, eucalyptus, or tea tree oils near closets, cabinets, storage spaces, and damp corners to make these areas less attractive to silverfish. Combine natural repellents with moisture control and sticky traps to improve long-term prevention indoors.

Simple steps to use cedar and essential oils for silverfish control include:

  • Place cedar blocks or chips in enclosed spaces: Keep cedar chips, blocks, or sachets in closets, drawers, cabinets, under sinks, and storage bins, as strong cedar scents help repel silverfish from dark hiding places.
  • Prepare a cedar oil spray for active areas: Mix 10 to 15 drops of cedar oil with 1 cup of water and a small amount of witch hazel, then spray lightly around baseboards, closet corners, storage shelves, and gaps in walls where silverfish travel.
  • Use peppermint, lavender, eucalyptus, or tea tree oils: Add 15 to 20 drops of essential oil per cup of water to create a natural repellent spray for attics, cabinets, pantry edges, and behind furniture.
  • Apply sprays near humid hiding spots carefully: Focus on damp corners, plumbing areas, enclosed cabinetry, cardboard storage, and spaces behind appliances, as silverfish are most active in humid, undisturbed environments.
  • Refresh cedar materials and sprays regularly: Reapply sprays every few days, and replace old cedar blocks periodically, as fading scents become less effective against ongoing silverfish activity.

Use Chemical Silverfish Control Products

Apply chemical silverfish control products to reduce active populations inside bathrooms, kitchens, basements, attics, and other hidden infestation areas. Treat cracks, wall voids, plumbing gaps, and damp storage spaces where they remain active at night. Combine chemical treatments with moisture control and sticky traps for stronger long-term prevention.

Use the following chemical control methods to reduce silverfish infestations indoors:

  • Place boric acid bait packets in hidden areas: Use products such as Dekko Silverfish Paks, which contain 20% boric acid, in closets, drawers, under sinks, attic corners, and along baseboards, because silverfish ingest the bait while feeding. Place 2 to 3 packets per 100 square feet in active areas.
  • Apply orthoboric acid dust into cracks and wall voids: Use dusts containing 5% orthoboric acid behind baseboards, around plumbing lines, in wall gaps, and under cabinets, where silverfish commonly hide.
  • Spray liquid insecticides around entry points: Apply products such as Cyzmic CS, Talstar P, or Ortho Home Defense Max around pipe openings, window frames, behind toilets, and damp corners to create residual indoor barriers.
  • Treat exterior foundations with perimeter sprays: Spray crawl space openings, foundation edges, door thresholds, and exterior wall gaps to reduce silverfish insects entering from moisture-prone outdoor areas.
  • Follow chemical safety instructions carefully: Wear gloves during application, keep children and pets away from treated areas, avoid overapplying chemicals indoors, and follow all product label directions for safe use.

Call a Pest Control Expert for Severe or Persistent Infestations

Contact a pest control expert when silverfish activity continues despite repeated cleaning, moisture control, traps, and home treatments. Seek professional treatment if silverfish keep appearing in bathrooms, basements, attics, closets, or multiple rooms, as these signs often indicate hidden populations in wall voids, crawl spaces, plumbing gaps, and damp storage areas.

Licensed pest control professionals inspect baseboards, plumbing lines, wall voids, attic corners, and hidden harbourage areas to locate active silverfish nesting zones. For severe or persistent infestations, professional Pest Control services apply commercial-grade crack-and-crevice treatments, residual insecticide barriers, bait systems, and insecticide dusts that target hidden populations more effectively than most DIY products. Continue supporting professional treatment with moisture reduction, sanitation, food source removal, and crack sealing, since silverfish infestations often return when indoor humidity and hidden entry points remain untreated.

How Can You Identify a Silverfish Infestation?

To identify a silverfish infestation, look for small silver-gray teardrop-shaped insects at night, scurrying into dark cracks and crevices, chewed holes in books or wallpaper, holes in fabrics and pantry items, black pepper-like droppings, and translucent shed skins in dusty areas. These infestation signs usually indicate active feeding, hiding, and breeding activity inside humid, dark, and undisturbed indoor spaces such as bathrooms, basements, attics, closets, storage areas, and baseboards.

8 Signs of a Silverfish Infestation Indoors

Spotting Small Silver Gray Teardrop-Shaped Insects at Night: Identifies active silverfish infestations through nighttime sightings of fast-moving silver-gray insects in dark and humid indoor areas.

Seeing Silverfish Scurrying Into Dark Cracks and Crevices: Reveals hidden harbourage areas when insects rapidly retreat into gaps in walls, baseboards, or floor crevices after light exposure.

Irregular Chewed Holes in Books, Documents, and Wallpaper: Indicates silverfish feeding activity through uneven paper damage caused by insects consuming starches, cellulose fibres, and glue adhesives.

Small Holes or Notches in Fabric, Clothing, and Pantry Items: Detects infestations through damage to fabrics, pantry packaging, and stored goods containing natural fibres or starch-based residue.

Unexplained Yellow Stains on Fabric or Storage Surfaces: Highlights possible activity areas through yellow marks left behind from feeding, moulting, or excrement near hidden infestation zones.

Tiny Black Pepper-Like Droppings in Corners and Baseboards: Confirms silverfish presence through small black fecal pellets commonly found near feeding paths, storage edges, and dark indoor corners.

Translucent Shed Exoskeletons in Dusty or Dark Areas: Identifies ongoing silverfish growth and harbourage activity through pale shed skins collected in humid and undisturbed spaces.

Signs of Activity in Bathrooms, Basements, and Attics: Signal active infestations in humid, dark, low-traffic areas with moisture, clutter, and hidden storage spaces.

  • Spotting Small Silver Gray Teardrop-Shaped Insects at Night

Look for small, silver-gray, teardrop-shaped insects moving across floors, sinks, baseboards, or storage areas at night, as silverfish are most active in dark, humid conditions. Recognize them by their metallic gray colour, flattened bodies, long antennae, and swift, wriggling movement. Watch for them darting into cracks or crevices when exposed to light, as repeated nighttime sightings typically indicate an active infestation indoors.

  • Seeing Silverfish Scurrying Into Dark Cracks and Crevices

Watch for silverfish rapidly scurrying into dark cracks, wall gaps, baseboard openings, cabinet corners, or floor crevices when the lights turn on, because these insects avoid bright environments and are most active at night. Check hidden areas near bathrooms, kitchens, storage spaces, and plumbing fixtures, as they prefer humid, undisturbed harbourage zones. Repeatedly seeing silverfish disappear into small openings usually indicates hidden nesting and breeding activity inside nearby wall voids or enclosed indoor spaces.

  • Irregular Chewed Holes in Books, Documents, and Wallpaper

Check books, paper documents, cardboard boxes, and wallpaper surfaces for uneven holes, scraped patches, or damaged edges, as these pests consume starches, cellulose fibers, and glue adhesives found in paper-based materials. Examine bookshelf corners, wallpaper seams, storage boxes, and stacked papers closely, as silverfish feeding damage often develops in dark, low-traffic indoor areas. Continued paper deterioration usually signals active hiding and feeding activity nearby.

  • Small Holes or Notches in Fabric, Clothing, and Pantry Items

Identify a silverfish infestation by checking clothing, fabric storage, pantry packaging, and dry food containers for small holes, irregular notches, or surface damage, as they feed on natural fibers, starches, sugars, and food residue. Inspect wool clothing, cotton fabrics, flour bags, cereal boxes, paper packaging, and stored pantry goods carefully, as they often stored in dark, undisturbed indoor storage areas.

  • Unexplained Yellow Stains on Fabric or Storage Surfaces

Unexplained yellow stains on fabrics, cupboard shelves, paper, or storage surfaces may indicate pest activity, as silverfish can leave marks from excrement, moulting, or feeding. Inspect clothing, linens, wallpaper edges, cardboard boxes, and dark storage areas carefully, since these stains often form near hidden harbourages. Multiple warning signs, including shed skins and paper damage, usually confirm an active infestation nearby.

  • Tiny Black Pepper-Like Droppings in Corners and Baseboards

As silverfish move through hidden indoor areas, they can leave behind tiny black pepper-like droppings around baseboards, shelf corners, floor crevices, and storage edges. Inspect bathrooms, closets, cabinets, and dark storage spaces carefully, as these small fecal pellets often accumulate near active feeding and hiding zones. Notice black specks along with shed skins, paper damage, or nighttime sightings, as multiple infestation signs usually indicate active silverfish indoors.

  • Translucent Shed Exoskeletons in Dusty or Dark Areas

Check dusty corners, closets, storage boxes, baseboards, and areas behind furniture for translucent shed exoskeletons, since silverfish regularly shed thin, pale skins near their hiding spots. Moulted skins frequently collect in dark, humid, and low-traffic indoor spaces where these insects remain active. Help reduce recurring infestations by controlling indoor moisture, sealing gaps in walls, and properly organizing paper products and fabrics, as cluttered, damp conditions often encourage activity indoors.

  • Signs of Activity in Bathrooms, Basements, and Attics

Inspect bathrooms, basements, and attics for silverfish activity, as they commonly thrive in dark, humid, low-traffic indoor environments with excess moisture and hidden storage spaces. Look around sinks, bathtubs, plumbing lines, storage boxes, baseboards, and attic corners for silverfish sightings, shed skins, droppings, or paper damage, as these signs usually indicate active feeding and breeding nearby. Help prevent infestations by improving ventilation, reducing humidity, and removing damp clutter from these indoor areas.

You can try to get rid of silverfish yourself when infestations are small, sightings are occasional, or minor moisture problems can be managed, and call a professional pest control expert when silverfish activity spreads across multiple rooms, damages fabrics or paper, or persists despite repeated DIY efforts.

Try DIY silverfish control when:

  • Small numbers of silverfish appear occasionally indoors
  • Minor moisture problems can be controlled with ventilation or dehumidifiers
  • Sticky traps, Diatomaceous Earth, or boric acid baits help reduce activity
  • Cracks, gaps, and entry points can be sealed easily
  • Paper clutter, cardboard storage, and exposed food sources can be removed
  • Routine cleaning and prevention are needed around humid indoor spaces

Hire a professional pest control expert when:

  • Silverfish activity spreads across multiple rooms or storage spaces
  • Books, wallpaper, fabrics, or pantry items show ongoing damage
  • Large numbers of silverfish appear regularly at night
  • DIY treatments fail to reduce infestation activity indoors
  • Hidden moisture problems exist behind walls or plumbing fixtures
  • Unsafe pesticide use or ignored humidity problems worsen infestations indoors

How Much Does It Cost to Get Rid of Silverfish?

The cost to get rid of silverfish ranges from $150 to $700 for professional extermination services, while routine pest control maintenance visits typically range from $100 to $500, depending on property size and infestation severity. Small infestations may only require traps, moisture control, and localized treatment, whereas severe silverfish problems inside walls, attics, basements, or storage spaces often need professional inspections, residual insecticide applications, crack sealing, and follow-up pest management treatments.

How Long Does It Take to Get Rid of Silverfish?

It takes 2 to 4 weeks to reduce silverfish populations using DIY methods such as sticky traps, Diatomaceous Earth, and moisture control. Complete elimination often requires more time because they can survive for months without food and continue breeding in hidden, humid areas. Severe infestations may need professional extermination, which can extend treatment to 1 to 3 months to fully break their life cycle.

What Attracts Silverfish to Your Home?

Silverfish are attracted to high humidity and moisture levels, leaking pipes and damp surfaces, starchy food sources like cereals and grains, paper and cardboard storage, cluttered spaces, and dark, undisturbed areas. These conditions provide silverfish with moisture, accessible food, hidden hiding spots, and secure breeding environments commonly found in bathrooms, kitchens, basements, attics, closets, and storage spaces.

  • High Humidity and Moisture Levels

Silverfish thrive in humid indoor environments where excess moisture helps them survive longer, reproduce faster, and remain active throughout the night. Bathrooms, basements, laundry rooms, crawl spaces, and poorly ventilated storage areas commonly attract moisture when indoor humidity stays consistently high, especially above 50%.

  • Leaking Pipes and Damp Surfaces

Persistent moisture from leaking pipes, damp cabinets, condensation buildup, or wet baseboards can quickly attract silverfish into nearby indoor areas. Plumbing spaces under sinks, around water heaters, behind appliances, and near bathtubs often create protected harbourage zones where these insects feed and breed undisturbed.

  • Starchy Food Sources Like Cereals and Grains

Open cereals, flour, oats, grains, pasta, and pet food can encourage silverfish activity because these insects feed on starches, carbohydrates, sugars, and food residue. Pantry shelves with unsealed dry goods, crumbs, or spilled food particles commonly increase their  feeding activity inside kitchens and food storage areas.

  • Paper, Books, and Cardboard Storage

Books, cardboard boxes, newspapers, magazines, and stored documents commonly attract silverfish because they consume cellulose fibers, paper coatings, and adhesive glue in paper-based materials. Long-term storage of paper in dark, dusty, or humid spaces often creates ideal nesting and feeding environments indoors.

  • Cluttered and Rarely Cleaned Spaces

Cluttered spaces with dust, debris, paper, and hidden organic materials provide ideal hiding areas for these pests. Packed closets, storage rooms, crowded shelves, and neglected corners allow populations to spread undisturbed, so regular cleaning and organization help limit the risk of infestation.

  • Cracks, Gaps, and Entry Points

Small cracks around walls, baseboards, flooring, plumbing lines, and vents can invite silverfish indoors by providing protected entry routes and hidden shelter. They commonly travel through narrow openings in structures, such as between walls, cabinets, ceilings, and enclosed storage spaces.

  • Dark and Undisturbed Areas

Low-light indoor environments naturally attract silverfish because these insects avoid bright conditions and are most active at night. Attics, closets, cabinets, storage corners, crawl spaces, and enclosed boxes commonly provide low-traffic harbourage for silverfish during the day.

  • Old Wallpaper and Wall Adhesives

Peeling wallpaper, aging wall coverings, and exposed adhesive glue often promote silverfish activity because silverfish feed on starch-based adhesives and deteriorating paper. Moisture-damaged wallpaper seams and loose wall coverings commonly become feeding and hiding zones indoors.

  • Fabric and Natural Fibre Materials

Natural fiber materials such as cotton, linen, wool, and silk, as well as starched clothing, can attract silverfish into storage areas when organic residue and moisture remain trapped in fabrics. Dark wardrobes, fabric storage bins, folded linens, and undisturbed textile areas commonly support ongoing feeding and nesting activity indoors.

What Are Common Mistakes to Avoid in Silverfish Control?

The common mistakes in silverfish control include ignoring moisture, leaving food exposed, and failing to seal entry points, which allow them  to continue feeding, hiding, and breeding in kitchens, bathrooms, basements, closets, and storage areas. Addressing these issues promptly reduces the risk of persistent infestations.

Common mistakes to avoid in silverfish control:

  • Ignoring moisture buildup in bathrooms, basements, or kitchens.
  • Leaving flour, cereals, pet food, or pantry items exposed.
  • Failing to seal cracks, gaps, and wall openings.
  • Storing cardboard boxes or paper clutter in dark, damp spaces.
  • Using unsafe chemical products or overapplying pesticides.
  • Neglecting regular cleaning of floors, shelves, and hidden storage areas.
