KNOCK DOWN™ POT-IT™ Plant Hanging Pest Traps attract and catch the most common potted plant pests (fungus gnats, greenflies, white flies, thrips, midges, spider mites, and other flying and crawling insects) without the use of pesticides or chemicals. The traps work by attracting unsuspecting pests to the natural yellow colour thinking it is a weakened plant. Once they land on the traps they are stuck and are ready to be discarded. Simply wait for traps to fill with pests and replace them with new traps until your insect problem has been controlled. 
The package contains 5 large double-sided glue traps.
