The 5 Most Hard-to-Detect Pests

grain beetlesMost people share their home with unwelcome guests: pests. They are eager to settle into your house if they can find food, water, and shelter. Most pests are extremely skilled in finding the best hiding places in and around your home. They love to hide in your attic, in the basement, in bathrooms, inside wall voids, and in countless other places. That’s why it’s so important to do a proper pest control regularly.

Fall pest control is important because it’s the only way to prevent pests from entering your home in search of a shelter to overwinter. Some invaders also bring viruses and diseases, so it’s important to detect them on time. Here are some hard to detect pests you should watch out for!


Termites* are home wreckers. They are a serious threat to your home, and it’s no wonder that they’re usually called the silent destroyers. They may be hiding in your home without any clear or significant signs of damage. It’s usually hard to notice them until they’ve done some major damage and that’s why they’re such a dangerous pests.

Carpenter Ant

Carpenter ant nests are difficult to find because they build colonies in moist wood structures. They cut galleries into the wood to form their nest, but they don’t eat the wood. You may notice signs of a carpenter ant infestation like wood shavings, but it’s hard to locate a nest by yourself. They can do a significant damage to your house, so it’s best to call a pest control professional if you suspect you have a nest somewhere inside your house.

Grain Beetle

These small pests feed on flour, cereal, and other dry goods commonly stored in your pantry. They are common in homes and grocery stores. They are hard to detect because of their size and where they like to live. An adult is 3–4 mm long so a homeowner need to look really hard to notice these pests.


Adult fleas are small and wingless, usually about 2 mm long. These blood-sucking pests commonly feed on hairy animals like dogs, cats, rats, and mice. When your pet has fleas, it’s hard to notice if your home has them too. Their eggs are not attached to the host, so they can hatch in rugs, carpets, in the cracks between floorboards, and virtually anywhere else around your house. They spread extremely fast: the egg hatch within two days. When they attack you and start to bite your legs, you will notice them. By that time, they’ve probably spread all over your household, so you’ll need to call a pest control professional to deal with the infestation.

Bed Bugs

Bed bugs are extremely hard to notice at first. That’s because they’re active during the night and they bite while you’re sleeping. These pests can move quickly over floors and walls. They are also capable of reproducing really fast, so they’re very hard to get rid of.  They are also very small, so rather than looking for bed bugs themselves, it’s important to know and watch out for the signs of a bed bug infestation.
