For many people, pests are a part of life. Ants can sneak into your kitchen and bring back that breakfast you left unattended.

While it’s impossible to keep bugs out of your house entirely, there are several ways to prevent them from becoming a nuisance.

In fact, some household insects bite or sting. And some even carry diseases that can make you sick. The best way to keep pests out of your home is to seal off cracks and crevices where they might find their way in.

List of Pests: A to Z

Ants are one of the most common insects found in the home, with the red imported fire ant being one of the worst kinds to have in your house. They’re attracted to sweets, so keep your food in sealed containers.

Bed Bugs

Bed bugs are often found near beds. You can tell if you have bed bugs if you see small brown or red spots on your mattress or sheets.




Beetles are the most successful group of animals on earth. They are found in all parts of the world, have evolved to live in diverse habitats, and are represented by over 400,000 different species. Most beetles feed directly on plants or plant matter, but some eat fungi or animal food, while others are predatory.

Carpenter Ants

Camponotus spp.

carpenter ant

Carpenter ants are some of the most destructive invasive pests in the United States. They can cause extensive damage to homes, trees and other structures. They get their name from their preference to nest in wood and other cellulose materials such as cardboard and paper, but they will also infest drywall and other soft building materials. Carpenter ants can cause serious structural damage to your home.


Class Chilopoda


Centipedes are arthropods that have one pair of antennae, a segmented body, and many pairs of legs. They are generally found in the tropical regions of the world, but they have also been introduced to other parts of the world. Centipedes are carnivores, and their diets typically include insects or other invertebrates like worms and snails. There are around 3,000 different species of centipedes found today.

Cockroaches (Roaches)

Order Blattodea


Cockroaches are among the most resilient pests on Earth. They are able to survive in the harshest environments, including nuclear fallout. This is largely because of how they are built, but cockroaches have evolved to take advantage of other organisms and even buildings in their quest for survival. Let's take a look at some of the features that make cockroaches so hardy and why we should consider taking a few lessons from them when it comes to building our own fortresses.

Order Orthoptera


These bugs can be easily identified from their long antennae and their very long legs that help them jump. They have wings but cannot fly, which is why they’re usually found around houses and buildings. Crickets are very likely to be found in attics, basements or crawl spaces. They can also be found outdoors under logs or rocks. Crickets typically enter homes through cracks and crevices around doors and windows.


Order Dermaptera


These common household insects are brown in color and have pincers near the end of their body. Earwigs are nocturnal insects that are also known as pincher bugs or leatherbugs. Their name comes from the pair of forceps at the end of the abdomen, which is used for defense. The forceps can pinch with great strength, but earwigs do not bite or sting humans.


Order Rodentia


Fleas are easily recognizable by their size, shape, and color. They are about 1/8-inch long with a flat body, oval-shaped head, and six legs. Their bodies can be brown or black depending on the species of flea that bit you. There are other common household bugs that resemble fleas that should not be confused with them. Flea bites look like red bumps with white spots in the middle which is caused by an allergic reaction to their saliva when they bite humans or other animals.


Family Diptera

house fly

Flies are a common pest that have the potential to spread germs and viruses to people. Stable flies and horse flies (sometimes known as "biting flies") feed on mammalian blood and can bite painfully. Some will be mild annoyances, while others will make you and your family members quite sick. Small insects such as fruit flies, fungus gnats, and others are considered pests.


Subclass Acari

Mites are arthropods, not insects, and are distant relatives of spiders and ticks. The majority of mites feed on other insects or decaying plant and animal matter. Dust mites, for example, primarily feed on dead skin cells. While mites seldom transmit illness to humans, they do have an influence on health in a variety of ways, ranging from being a nuisance when they enter houses in high numbers to causing severe skin irritation and acute itching.



Mosquitoes are common, flying insects that live in most parts of the world. Over 3,500 types of mosquitoes can be found worldwide.

You could also try calling a local pest control company to avoid these house pests spreading disease.


Order Lepidoptera


Some moths can cause lepidopterism or caterpillar dermatitis, which can be fatal. This is a skin ailment that occurs when moth and butterfly caterpillars come into touch with the skin. Some moth larvae's hair (spines) can induce allergic reactions. Call pest control experts in your area to get rid of moths and other pests.


Order Rodentia

rodent eating

Mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters are examples of well-known rodents. The majority of rodents are tiny creatures with strong bodies, short limbs, and long tails. They can cause food contamination which is why they are considered common pests and are commonly found in your house if you live in a dense rural area like Chicago or New York.


Class Arachnida

There are more than 45,000 known species of spiders, found in habitats all over the world. They are common house insects and may require a pest control professional to come into your property to protect you and your family from living in a home full of house pests. One of the most dangerous spiders is the black widow.

Stinging Pests
