Control small flying insects such as aphids, whiteflies, thrips, fungus gnats, scale insects and other pests in gardens, homes, and greenhouses with a BioCare Aphid and Whitefly Trap. The special yellow color attracts the insects to the trap - the powerful glue kills them. The glue is vegetable-based, not petroleum based like other brands. Paper backing makes the whole trap composable when full of insects.
