Common Household Bugs, Pests & Insects

Not too long ago a study concerning the most common household bugs and insects had become popular on the internet. However, when it comes to the ecology of our indoor living areas, there is still not much that is known. No matter how clean you keep your home, there are certainly spiders and insects lurking in areas that you would never think to look. Surprisingly, indoor areas are not well studied. A recent study has shown that the average home contains around one hundred different creepy crawlies. These one hundred different bugs could not be more different from one another, and just about all of them are well adapted to indoor living.

Most common household bugs that dwell inside include:

  • booklice

  • gall midges

  • weevils

  • fruit flies

  • ants

  • cockroaches

  • carpet beetles

  • dark-winged fungus gnats


According to Dr. Bryan Lessard, an entomologist with the CSIRO’s Australian National Insect Collection, the biodiversity within our homes is far broader than many had probably assumed. These researchers vacuumed floors and peeked into every nook and cranny of a home in order to find every bug they could. Some homes have as many as two hundred and eleven different bugs thriving in hidden areas. However, the average is ninety-three different species per house. Fun Fact: most well-adapted bugs that thrive indoors also enjoy eating what humans eat, such as cereal and salty snacks.

Booklice are on the list amongst common household bugs. These pests are often found feeding on the same food that we do, such as rice or flour — but they also feed on mold. Wolf Spiders are also a common pest and tend to frighten home-dwellers. These spiders do not build webs; instead, they wander through homes looking for prey. Luckily, wolf spiders are shy and their bites will not cause medical issues in most cases.

On the other hand, there is the Black Funnel-web spider, and these are a bit larger than wolf spiders. You know these spiders are somewhere in your home when you find untidy webs around your windows or light fixtures. These spiders are trying to catch flying insects with these lazily made webs. Although these spiders are shy and are not likely to bite, they can still be quite frightening to those suffering from arachnophobia. It should be noted, that most bugs living in your home now are about as big as a pinhead.

One of the uglier and all-around more disturbing-looking pests that are commonly found within peoples’ homes are European Centipedes. These nasty creatures have thin legs that look like wavy strands of hair. They are found in moist areas like bathrooms, eat smaller insects, and can travel very fast.
