Sticky cards are glue-based traps frequently used in pest control to catch and monitor insects and other pests. Typically, sticky cards consist of a sticky glue layer mounted on a piece of cardboard that is folded into a tent-structure to protect the sticky surface. Most sticky traps contain no pesticides, although some may be impregnated with aromas designed to be attractive to certain pests. Sticky traps are quite valuable to growers. They are used for one of two things: Trapping or monitoring.
