It can kill adult beetles and reduce their population in your yard. Did you find grubs in your lawn last spring? Then you may need to apply a grub preventer for lawns. You do not need to apply grub control every year successively unless you see grub damage. Grub preventers help control grubs for every next season.
You cannot apply a grub preventer to kill grubs that are already damaging your lawn. For that, you need to apply a grub killer such as GrubEx. Otherwise, you need to apply the insecticide between May and July to prevent infestation for the next season by killing and harming the development of the next generation of grub worms in your lawn. In healthy turfs, a few grubs should not be a problem and you may not need to apply insecticide every other year.
You only need to start a grub control treatment when you see signs of damage. If you feed your lawn properly, your grass can support about 5 grubs per square foot of turf without any visible damage. Your lawn will still look green and healthy because the damage from their feeding activity will be very minimal. Most homeowners mean to kill grubs when they see signs of infestation. However, the best way to control their damage for the long-term is by putting down a preventer. The reason why you want to look for these ingredients is that they are very good at killing grubs at a tender age, usually as soon as they hatch.
Grub treatments are effective when applied at the right time. In some cases, you may need to apply the pesticide two or three seasons in a row to completely eradicate grubs in your lawn. The best time to apply GrubEx is early spring through mid-summer when grub activity in lawns in heightened. There are curative grub control products that can be applied to the turf at this time late August through October that will control the grubs in as little time as one to three days.
Without active grub feeding in turf, most predators do not detect grubs in the turf and they look elsewhere for their meals. Curative grub control products work much faster on existing grubs and provide little-to-no residual insecticide control. One leading product is Dylox, which contains trichlorfon. Once watered into the turf, it begins working immediately to kill grubs.
At this time, the grubs are usually third instar the maximum size for the first summer before winter resting , which is the hardest stage to control, but trichlorfon often reduces the population by 70 percent sometimes more than 70 percent. This dramatic reduction eases the root pruning, and thins the food population for predators, causing them to look elsewhere for food. As the predators leave your turf, the damage they cause also departs, leaving you to begin your late fall, early winter turf maintenance program.
