Spectracide Triazicide Insect Killer For Lawns & Landscapes Concentrate protects lawns, vegetables, fruit and nut trees, roses, flowers, trees and shrubs with a formula that controls insects above and below ground. It controls more than 260 listed insects by contact, including grubs, ants as listed, fleas, deer ticks, Japanese beetles, European crane flies and other listed insects. Available as a dilutable concentrate designed to be applied with a tank sprayer (sold separately) and as a ready-to-spray QuickFlip spray concentrate that attaches directly to your garden hose. For best results, apply this formula early before insect populations are high. Wet leaves and branches to the dripping point. Try to spray the underside of leaves and penetrate dense foliage. Be sure to follow the important use limitations for the specific vegetable you are treating, including the intervals between treatments and the days to wait before harvest.
