A small, gray, land-dwelling crustacean that rolls into a tight ball when disturbed, lives in damp soil and leaf litter, and feeds harmlessly on decaying plant material.Drain Fly

A longhorned beetle whose larvae tunnel for years inside seasoned softwood timbers, most often pine, slowly weakening structural wood in buildings.Oriental Cockroach

A small reddish-brown wood-boring beetle whose larvae feed on the starch in hardwood sapwood, leaving round pinhole exits and a fine, flour-like powder that gives the group its name.Red Flour Beetle
A tiny, shiny reddish-brown beetle that infests flour, cereal, and other dried, finely ground foods in pantries, mills, and warehouses, contaminating far more than it eats.Rice Weevil
A tiny reddish-brown snout beetle whose grubs develop hidden inside whole grain kernels, making it one of the most damaging pests of stored grain, flour, birdseed, and pantry staples worldwide.Roof Rat
A slender, climbing rat that nests above ground in attics, trees, and dense vegetation, travels overhead along wires and rooflines, and is especially fond of fruit and citrus.Sawtoothed Grain Beetle

A large, hairy, ground-dwelling hunting spider that chases down prey on foot instead of spinning a web, sheltering under boards, stones, and siding and sometimes wandering indoors near ground level.Yellow Fever Mosquito
