aphid

Downtown's Pershing Square supports mourning doves, Vaux's swifts, gopher snakes and exotic streaktails, a type of fly that feeds on aphids.

Acephate and malathion belong to a class of chemicals called organophosphates, which U.S. farmers have used for decades because they efficiently kill aphids, fire ants and other pests.

Mosquitoes, aphids and flies, however, must settle for dripping.

Tanglefoot, a sticky, gooey substance, can be applied near the base of a tree to stop ants from reaching the aphids.

No sooner do fresh buds appear then they are covered in aphids, beetles and other bugs looking for a tasty snack.
