If you’ve ever discovered a cluster of creepy crawlies in your home, you know the unsettling feeling that comes with it. Moisture-loving insects such as earwigs, silverfish, ants, and springtails are notorious for invading our living spaces.
These pests may be tiny but can cause significant issues if left unchecked. Understanding these pests is the first step toward maintaining a pest-free environment, whether dealing with an infestation or just looking to prevent one.
What are moisture-loving insects?
Moisture-loving insects are pests that thrive in damp, humid environments. They often seek out areas in your home where moisture accumulates. Among the most common are earwigs, silverfish, ants, and springtails.
These insects are drawn to wet, dark places like basements, bathrooms, and kitchens, where they find the ideal conditions for survival and reproduction. Leaky pipes, condensation, and poor ventilation can create the moist environments these insects love.
If left unchecked, they can damage household items, contaminate food supplies, and even indicate a larger moisture problem.
Identifying Earwigs and Other Pests
By being aware of various moisture-loving insects’ characteristics, you can better identify and manage infestations.
Earwigs
Earwigs have long, flat bodies, typically dark brown or reddish-brown, and range in size from about 0.2 to 1 inch. One of their most distinctive features is the pair of pincers protruding from their abdomens.
If you suspect an earwig infestation, here are some tell-tale signs to look out for:
- Visible sightings: Earwigs are nocturnal, so you’ll likely spot them at night. During the day, they hide in areas such as under rocks, mulch, and in leaf litter.
- Damaged plants: Earwigs feed on living and dead plant matter. Look for signs of chewed leaves and flowers, particularly at the base of plants.
- Clusters: These insects gather in large numbers, especially in moist environments. If you disturb their hiding places, you might see a cluster of earwigs scatter.
Are earwigs harmful to humans?
Earwigs are not harmful to humans. Earwigs do not carry diseases, do not sting, and are not poisonous. The primary concern with earwigs is that they can become a nuisance if they enter homes in large numbers.
While their pincers may look intimidating, earwigs do not pose any real threat. Earwigs can use their pincers defensively, but they rarely pinch humans, and even if they do, the pinch is harmless and not painful.
Silverfish
Silverfish are wingless bugs about ½ to ¾ of an inch long. They have a distinctive silvery-gray color and fish-like movements. They thrive in humid environments and are often found in basements, bathrooms, and kitchens.
Look out for:
- Paper damage: Silverfish feed on starchy materials, so they may munch on wallpaper, books, and cardboard boxes.
- Yellow stains: They leave behind yellowish stains on paper and fabric.
- Visible sightings: These nocturnal creatures are often seen darting away when disturbed.
What do silverfish hate the most?
Dry environments, cedar, cinnamon, cloves, lavender, citrus, and bay leaves most repel silverfish.
You can sprinkle or place any of these items in areas where silverfish are present. Many of these items put off scents silverfish hate.
Ants
Ants are highly social insects that can form large colonies. Some species, like carpenter ants, are particularly attracted to moisture-damaged wood. You can identify an ant infestation by:
- Trails: Ants often leave visible trails as they forage for food and water.
- Damage: Carpenter ants can cause structural damage by hollowing out wood to build their nests.
- Nests: Look for nests in moist, wooded areas or inside your home (if there is water damage).
What is the most common house ant in the Pacific Northwest?
The most common house ant in the Pacific Northwest is the Odorous House Ant (Tapinoma sessile). These ants are known for their strong, unpleasant odor when crushed, which smells like rotten coconut. Odorous house ants are tiny, typically about 1/8 inch long, and range in color from dark brown to black.

Springtails
Springtails are tiny, wingless insects that can jump great distances relative to their size. They are usually found in damp soil, leaf litter, or under mulch. They are often seen indoors around sinks, bathtubs, and potted plants.
Identifying features include:
- Small size: They are very small, usually less than 6 mm.
- Jumping ability: Springtails can leap great distances when disturbed.
- Moisture presence: They are always found in damp areas.
Are springtails harmful to humans?
Springtails are not harmful to humans. These tiny insects do not bite, sting, or transmit diseases. Their primary diet consists of decaying organic matter, fungi, and mold.
Why do I have moisture-loving insects in my house?
Understanding why these pests are drawn to your home is the first step in preventing infestations.
- High humidity levels: Many of these insects thrive in humid conditions. Basements, bathrooms, and kitchens are typical hotspots due to the presence of water and poor ventilation.
- Cracks in foundations: Small cracks and crevices in your home’s foundation provide easy entry points for insects.
- Cluttered, damp spaces: Piles of clutter – especially in damp areas like basements – create perfect hiding spots for these insects.
Specific Attractants:
- Earwigs: Seek out decaying plant matter and other insects. They prefer moist environments and can often be found in gardens or under mulch.
- Silverfish: Attracted to paper, cardboard, and starchy materials. They love to hide in old books, magazines, and stored clothing.
- Ants: Drawn to food sources, especially sugary and greasy foods. Carpenter ants, in particular, are attracted to moisture-damaged wood.
- Springtails: Highly attracted to moisture and decaying organic matter. They’re commonly found in damp areas and around houseplants, where they feed on mold, fungi, and algae.
Why am I seeing more bugs in the winter?
This is because many moisture-loving insects seek warmth and shelter during winter.
- Seeking warmth and shelter: Just like us, these pests want to stay warm during the winter. They migrate indoors to basements and other damp, insulated areas to escape the cold.
- Basements and damp areas: Basements are particularly attractive to these insects because they offer a combination of warmth, moisture, and secluded hiding spots.
Prevention Strategies
By implementing these prevention strategies, you can create a less inviting environment for moisture-loving insects and keep your home pest-free.
Reducing Moisture in Your Home
Keeping your home dry is the first step in preventing earwigs, silverfish, and other moisture-loving insect infestations. Here are some practical tips to help you maintain a dry and comfortable living space:
- Use dehumidifiers: Dehumidifiers reduce humidity levels in moisture-prone areas. Set them up in areas where moisture tends to accumulate in your home.
- Fix leaks: Regularly inspect your home for any signs of leaks, whether from pipes, faucets, or the roof. Promptly repairing leaks will prevent water from creating an inviting environment.
- Improve ventilation: Check that your bathrooms and kitchens have exhaust fans to remove excess humidity. Opening windows and using fans can also help circulate air and reduce dampness.
- Verify proper drainage: Gutters and downspouts should direct water away from your foundation. Check that the ground slopes away from your house to prevent water from pooling around the foundation.
Sealing Entry Points
Preventing insects from entering your home in the first place is key to maintaining a pest-free space. Here’s how you can seal those sneaky entry points:
- Identify cracks and gaps: Regularly inspect your home’s exterior for cracks, gaps, and other potential entry points. Pay attention to areas around windows, doors, and the foundation.
- Seal entry points: Use caulk or weatherstripping to seal gaps and cracks. Expandable foam can be used for larger openings. Make sure that window screens are intact and repair any damage.
- Regular maintenance and inspections: Schedule regular maintenance to check that your home remains well-sealed. A little effort goes a long way in keeping pests out.
Proper Storage and Cleanliness
Maintaining proper storage and cleanliness can reduce the likelihood of pest infestations. Follow these best practices:
- Store food properly: Keep food items (including pet food) in sealed containers. Avoid leaving food out on counters and clean up spills immediately. This will help deter ants and other pests from seeking a free meal in your kitchen.
- Declutter regularly: Make it a habit to declutter areas like basements, attics, and garages so pests have nowhere to hide.
- Cleanliness is key: Vacuum and dust regularly, paying attention to corners and hidden areas where pests might hide. Keep your kitchen and bathroom surfaces clean and dry.
Basement Waterproofing
Checking that your basement and other damp areas are well-protected from moisture is an essential long-term solution for preventing pest problems. Here are some waterproofing strategies to consider:
- Sump pumps: Installing a sump pump in your basement can help remove excess water accumulating during heavy rains.
- Drainage systems: Proper drainage systems around your home direct water away from your foundation, reducing the risk of moisture seeping into your basement. French drains and foundation drains are effective solutions.
- Moisture barriers: Applying moisture barriers to your basement walls and floors can prevent water vapor from entering your home. These barriers can be waterproof paints, sealants, or plastic sheeting.
Specific Tips for Preventing Different Types of Insects:
- Earwigs: Remove piles of leaves, mulch, and other organic matter around your home’s foundation. Keep outdoor lights to a minimum, as earwigs are attracted to light.
- Silverfish: Store paper products, books, and clothing in sealed containers.
- Ants: Keep food sealed and clean up crumbs and spills promptly.
- Springtails: Keep houseplants on well-draining soil and avoid overwatering. Regularly clean areas prone to mold or mildew since springtails feed on decaying organic matter.
How to Get Rid of Earwigs, Silverfish, Ants, and Other Moisture-Loving Insects
By taking a proactive approach and utilizing a combination of natural remedies, commercial products, and professional services when needed, you can keep your home free of moisture-loving insects.
Natural Remedies and DIY Solutions
Taking a natural approach to pest control can be effective and safe for your family and pets. Here are some natural methods to repel moisture-loving insects:
- Essential oils: Many insects dislike the strong scents of essential oils such as lavender, peppermint, and tea tree oil. Mix a few drops of essential oil with water in a spray bottle and apply it to areas where you’ve noticed insect activity.
- Diatomaceous earth: This natural powder is made from fossilized algae and is effective against various pests. Sprinkle food-grade diatomaceous earth around the perimeter of rooms, in cracks, and other entry points. The tiny particles will dehydrate and kill the insects.
- Vinegar solutions: Vinegar is a versatile natural cleaner that repels insects. Mix equal parts of white vinegar and water in a spray bottle to clean surfaces and deter pests. Vinegar is especially effective against ants and can disrupt their scent trails.
DIY Pest Control Solutions:
- Earwig trap: Fill a shallow dish with soy sauce and a few drops of olive oil. Place it near areas where earwigs are seen. The soy sauce attracts them, and the oil traps them.
- Silverfish repellent: Make small sachets of dried herbs, such as lavender, rosemary, and cloves, and place them in closets, bookshelves, and other areas prone to silverfish.
- Ant barrier: Draw a chalk line or sprinkle cinnamon or coffee grounds around entry points. Ants won’t cross these barriers.
- Springtails: Mix a solution of equal parts white vinegar and water in a spray bottle. Spray it around windowsills, doorways, other entry points, and areas where springtails have been seen.
Commercial Pest Control Products
Commercial pest control products can provide an effective solution for more persistent infestations.
- Bug sprays and insecticides: Look for products targeting earwigs, silverfish, ants, and other moisture-loving insects. Choose sprays that are safe for indoor use and follow the instructions carefully.
- Choosing the right product: Consider the type of pest and severity of the infestation. For minor issues, a natural or mild insecticide may suffice. For more severe infestations, stronger products might be necessary.
