Small flying insect pests are attracted by the unique, colorful plastic of Safer"s Sticky Strips, and stick to the non-drying glue covering the trap. Many insects, particularly Whiteflies, Thrips, Leaf Miners and Aphids can be difficult to control with insecticides. By catching the winged adults with a STICKY STRIPS™ trap, before they reach the plants, the buildup of pests can be controlled. These double sided sticky traps can last several months and can be used indoors and outdoors.
