Why they like your basement

Like many other pests and rodents, bugs are drawn to cool, dark and moist places that have a steady food supply. Most basements are perfect for this! The cool, damp atmosphere provides a safe space to hide and a likely endless supply of other bugs to snack on.

Even if you don’t see any bugs in your basement, they’re likely still there. Most bugs tend to retreat and hide as soon as the light comes on so there’s a good chance you might not see them. One sure sign of bugs in your basement though is if you notice spiders hanging out. Spiders will build webs wherever they find a steady food supply.

Bugs in your basement


Most spiders around Toronto don’t pose any significant health threat to humans, so they’re relatively harmless guests in your basement. In fact, they can actually help keep other pest infestations under control since they like to eat most other bugs that they find.


These creepy crawlies also like to prey on other bugs so while they’re unappealing, they can actually help keep other bug infestations at bay. That doesn’t mean you have to live with them though! If you notice that you have some centipedes in your basement you can step up your cleaning game to reduce their food source before resorting to some more serious measures.


More likely to be found in dark and damp places like in sewers and outside in piles of leaves and stones, cockroaches are typically thought of as pretty unappealing. If you find cockroaches in your basement there’s probably a problem with sanitation or moisture somewhere. If you find cockroaches in your basement you should examine entrance points like floor drains and utility pipes for an excess of moisture.

Cockroaches have a pretty unpleasant appearance, as well as some serious health concerns. They can spread dozens of different kinds of bacteria and have been known to cause allergic reactions and asthma attacks, especially with kids. Because of this, a cockroach infestation is something you have to deal with quickly.


These small insects have large pincers that can make them look quite ominous to anyone that comes across them. Though they aren’t likely to actually get into your ear, they probably aren’t bugs you want to share your home with.
