Imidacloprid

Imidacloprid is the most widely used insecticide in the world. Its major uses include:
Agriculture – Control of aphids, cane beetles, thrips, stink bugs, locusts, and a variety of other insects that damage crops

Arboriculture – Control of the emerald ash borer, hemlock woolly adelgid, and other insects that attack trees (including hemlock, maple, oak, and birch)

Home Protection – Control of termites, carpenter ants, cockroaches, and moisture-loving insects

Domestic animals – Control of fleas (applied to the back of neck)

Turf – Control of Japanese beetle larvae (exp. Grubs)

Gardening – Control of aphids and other pests

When used on plants, imidacloprid, which is systemic, is slowly taken up by plant roots and slowly translocated up the plant via xylem tissue.
