What are ants?

Ants live in colonies usually made up of three castes; queens, which are female reproductives, workers or non-reproductive females, and reproductive males. Most ant colonies have multiple queens that produce many workers and larger colonies. However, colonies of any size can be overwhelming when they infest your property.

Beetles are insects with wings and wing covers, which create a shell-like body. The wing covers create a straight line down the middle of the back, which is one way you can identify these pests as beetles. They come in many different color variations and sizes.

What are cockroaches?

Cockroaches are known as some of the “dirtiest” pests because of the places they inhabit, such as sewers and dumpsters. Unfortunately, cockroaches pick up dangerous pathogens in these places, which they carry and spread. These pathogens can lead to E. coli, salmonellosis, cholera, and more.

What are crickets?

Crickets are nocturnal insects known for the chirping sounds they make. These sounds are created by male crickets rubbing their wings together to attract a mate. Crickets are subsocial insects, which means they mostly live alone, but do provide some care to offspring.

What are scorpions?

Scorpions are arachnids with eight legs, a hard exoskeleton, two pincers, and a curved tail that ends in a stinger. Most scorpions are nocturnal, spending their days in caves or other harborage areas and hunting for prey at night because scorpions usually become a problem in homes experiencing other pest issues.
