Thrips have been known to bite agricultural workers, causing a pin-prick sensation. They have chewing mouthparts. Have two or three bristles or tails at tip of abdomen. Thysanura exhibit nonmetamorphosis. They are household pests, feeding on such items as paste, paper, crumbs, etc.
Firebrats gather in the areas that are heated in the home, hence the name.
Possess an appendage on their ventral side which operates as a spring to aid the insect in a quick escape. Feed on decaying organic materials, such as rotting plants. They will on occasion attack plants, particularly in greenhouses. There are a number of other insect orders that are not pests of the home garden, but may be found in yards. Fleas of the order Siphonaptera may live in yards where pets or livestock are found.
