high risk

Termites

Termites are wood-destroying insects that cause billions of dollars in structural damage annually across the United States. They feed on cellulose found in wood and can silently destroy a home's foundation before being detected.

medium risk

Cockroaches

Cockroaches are resilient pests that thrive in warm, humid environments. They carry bacteria and allergens that can trigger asthma and allergic reactions, making them both a nuisance and a health hazard.

low risk

Ants

Ants are among the most common household pests in America. While most species are merely nuisances, carpenter ants can cause structural damage, and fire ants deliver painful stings that can cause allergic reactions.

medium risk

Bed Bugs

Bed bugs are small, flat, parasitic insects that feed exclusively on blood while people sleep. They have made a major resurgence across the United States and can be extremely difficult to eliminate without professional help.

medium risk

Mosquitoes

Mosquitoes are blood-feeding insects that are more than just a nuisance. They are vectors for serious diseases including West Nile virus, Zika virus, and Eastern Equine Encephalitis in the United States.

high risk

Rodents

Mice and rats are destructive rodents that contaminate food, spread disease, and cause property damage by gnawing on wires, insulation, and structural components. They reproduce rapidly and can be difficult to control once established.

low risk

Spiders

While most spiders are harmless and even beneficial, species like the brown recluse and black widow pose genuine health risks. Spider infestations often indicate the presence of other pest problems that serve as their food source.

medium risk

Wasps & Hornets

Wasps and hornets build nests near homes and can deliver painful stings, sometimes causing severe allergic reactions. Unlike bees, they can sting multiple times and tend to be more aggressive when their nests are disturbed.
