The Most Unusual Pests Found in Homes
Most homeowners expect the usual suspects: ants in the kitchen, spiders in the basement, maybe the occasional mouse in the attic. But sometimes, pests show up that make you stop and say, “What is that?”
These unusual invaders can be just as disruptive—if not more so—than their more familiar counterparts. And because they aren’t as well-known, they can go unnoticed longer, giving them more time to cause damage or spread.
In this post, we’re uncovering some of the strangest pests that might find their way into your home, how to spot them, and why a professional eye can make all the difference when the pest isn’t one you recognize.
1. Silverfish
These fast-moving, silvery insects thrive in humid environments like bathrooms, basements, and laundry rooms. They’re harmless to humans but love to chew on paper, glue, wallpaper, and even clothing.
Why they’re a problem:
Silverfish aren’t dangerous, but they can destroy valuable books, important documents, and stored clothing. They’re also hard to catch and multiply quickly.
Where they hide:
Behind wallpaper, under sinks, inside cardboard boxes, or in bathroom corners.
2. Earwigs
With their long pincers and slick brown bodies, earwigs look like something out of a sci-fi movie. Thankfully, they’re more creepy-looking than harmful.
Why they’re a problem:
Earwigs can find their way inside in large numbers, especially during hot, dry weather. While they don’t sting or bite, their presence in sinks, tubs, or closets can be unsettling and frustrating to manage without help.
Where they hide:
Under mulch, in damp soil, or around sinks and bathtubs.
3. House Centipedes
Long legs. Fast movements. A body that looks like it came out of a horror story. House centipedes are common in many regions but often mistaken for more dangerous creatures.
Why they’re a problem:
While they actually help by eating other bugs, they move fast and can scare the daylights out of you. They also signal a larger pest issue, since their presence often means there’s a steady food supply (aka other bugs).
Where they hide:
Basements, closets, behind baseboards, and in wall voids.
4. Fungus Gnats
Often confused with fruit flies, fungus gnats live in the soil of houseplants. They lay eggs in moist dirt and their larvae feed on plant roots.
Why they’re a problem:
These tiny flying insects can multiply rapidly and become an indoor nuisance. If left unchecked, they can damage your plants and become difficult to eliminate without the right treatment approach.
Where they hide:
In damp potting soil, especially near overwatered houseplants.
5. Booklice (Psocids)
Booklice aren’t true lice, but their tiny, pale bodies and preference for damp areas give them their name. They feed on mold and mildew, especially in high-humidity areas like bathrooms and basements.
Why they’re a problem:
While harmless to people, booklice can show up in large numbers and thrive in unseen moisture pockets. Their presence can be a clue that you have a hidden water or humidity issue in your home.
Where they hide:
Stored papers, window sills, wallpaper seams, or damp food packaging.
Why Unusual Pests Need Professional Attention
The biggest risk with unusual pests is misidentification. Homeowners may ignore or misjudge what they’re seeing—and that delay can give pests time to spread, nest, and cause costly damage.

We don’t believe in cookie-cutter treatments. Every home is different—and so is every solution.
What You Can Do as a Homeowner
While professional support is essential, there are a few steps you can take to reduce your risk of unusual pest problems:
- Reduce indoor humidity with dehumidifiers or exhaust fans
- Seal cracks and entry points around the foundation and windows
- Store paper and clothing in dry, sealed containers
- Check potted plants for gnat activity and avoid overwatering
- Keep basements and attics clean and clutter-free
- Inspect areas that stay moist, like under sinks or near drains
Even with these measures, some pests will find their way in. That’s why having a pest control plan in place is your best defense against surprises.
