All Pests

10 pests identified
Ants — pest identification
⚠ Medium Threat

Ants

Argentine, fire, pharaoh, and sugar ants are the most common invaders in Orange County. Some species bite, sting, spread disease, or damage electrical equipment.

Bed bugs — pest identification
🔴 High Threat

Bed Bugs

Reddish-brown hitchhikers that feed on human blood at night. Their bites disrupt sleep, cause skin reactions, and infestations spread rapidly through walls and floors.

Cockroaches — pest identification
🔴 High Threat

Cockroaches

Nocturnal scavengers that spread E. coli, salmonella, and trigger asthma in children. German, American, Oriental, and Brown-banded species are common in our area.

Rodents — pest identification
🔴 High Threat

Rodents

Rats and mice chew through wiring, insulation, and walls while spreading 35+ diseases. They reproduce rapidly — a small problem becomes a full infestation within weeks.

🔴 High Threat

Termites

Silent destroyers that cause billions in structural damage annually. Orange County's warm climate makes it one of the most termite-active regions in the US year-round.

⚠ Medium Threat

Spiders

Most spiders are nuisances, but black widows and brown recluses pose serious medical risks. Webs in corners, garages, and attics are common signs around OC homes.

🔴 High Threat

Stinging Insects

Wasps, hornets, and yellow jackets build nests in eaves, attics, and walls. Their stings trigger allergic reactions and they become aggressive when nests are disturbed.

⚠ Medium Threat

Fleas & Ticks

Fleas spread tapeworms and cause intense itching in pets and humans. Ticks transmit Lyme disease and Rocky Mountain spotted fever. Both thrive in OC's mild climate year-round.

✔ Low Threat

Silverfish

Fast-moving, wingless insects that feed on starchy materials — books, wallpaper, clothing, and pantry goods. Found in damp basements and bathrooms, they indicate moisture issues.

⚠ Medium Threat

Flies & Mosquitoes

House flies spread over 65 diseases by contaminating food and surfaces. Mosquitoes transmit West Nile virus and cause relentless outdoor discomfort in warm Southern California months.
