The Bug Guy's most wanted

Delaware Pest Library

Identification first. What it looks like, how it got in, what it does, and what actually removes it.

Trailing ants in Delaware kitchens are usually odorous house ants or pavement ants, not carpenter ants.

Large black ants that excavate damp wood rather than eat it, and often signal a leak somewhere.

German cockroaches breed indoors; American and Oriental roaches wander in from sewers, drains and basements.

Eastern subterranean termites work out of the soil and hollow Delaware framing from the inside.

Three mosquito species matter in Delaware, and each one breeds in a different kind of water.

Blacklegged, lone star and American dog ticks all occur in Delaware, and they are not equal risks.

House mice nest in wall voids and cabinets, breed through the winter, and pass through a quarter-inch gap.

The Norway rat is the rat found in Delaware - a burrowing rodent tied to sewers, alleys and farm outbuildings.

Bed bugs are a travel-borne insect, not a housekeeping failure, and they do not transmit disease.

Nearly every spider in a Delaware home is harmless, and none of them are brown recluses.

The brown marmorated stink bug overwinters in Delaware walls and attics, then appears indoors.

Paper wasps, yellowjackets and hornets nest close to Delaware homes and peak in late summer.

The cat flea breeds in carpet and pet bedding, not on the animal, which is why it keeps coming back.

A humidity pest that grazes on paper, starch and glue. Harmless to people, hard on books and boxes.

House centipedes hunt other insects in damp basements. Mostly a nuisance, and a useful signal about moisture.

Field, house and camel crickets in Delaware homes: the noise, the fabric damage, and how to tell them apart.

Solitary mining and sweat bees nest in bare spring soil: docile, useful pollinators that rarely need treating.

Pantry moths and clothes moths are two separate problems, and which one you have changes the whole treatment.
