The best lawn grubs killer
lawn grubs are white, C-shaped insects about 1/2 inch to 1 1/2 inches long with brown tips at both ends. They eat at the grass roots and cause spreading spots that can often be pulled up from the ground. These insects can be found at the root level of the lawn around the brown, affected areas. Information on various pit killers available helps homeowners choose the best product for their needs.
Biological predators are those that use natural predators and diseases to eliminate these pests in the garden. Milk spores are a bacterium called Paenibacillus popillae, which comes as dust that is applied to affected grasslands. Grubs use the trace material that reproduces inside their body, and then the grubs die. Milk spores are not effective on all types of lawns. The best effective use of this product is on Japanese beetles, according to Alabama Cooperative Extension entomologist Patricia P Cobb.

Favorable nematodes are small, worm-like creatures that invade the pit and release a bacterium that kills the pit. Nematodes come in a spray solution that is applied to the lawn area. The spray contains live nematodes and should be used as soon as possible after purchase. Heterorhabditis bacteriophora nematode is known to be effective against lawns, according to the University of Illinois. Favorable nematodes are the best choice for those who are concerned about the effects of pesticides on humans and the environment.
Effective on larger grubs later in the season, chemical lawns are considered a curative pesticide more than a preventative measure; Carbaryl provides good control over the pits of Japanese beetles, and is applied in liquid or granular form and then rinsed down to the root level to kill the pits. Grubs are removed in 10 to 14 days, according to Michigan State University author Terry Davis.

Halofenozide Grub Control
Halofenozide is a chemical insecticide used as a preventative measure to kill newly hatched larvae. Timing is important when using this product, as it will deteriorate if used prematurely before the pits hatch. It must be used before 15 July to allow rain to fall to the ground in preparation for the pits.
A chloronicotinyl type insecticide used as a preventative gravel killer is imidacloprid, which is applied early in the season to eliminate young larvae when they occur. Treat only in and around affected grasslands. Lawns infected with larger grubs later in the season may require a stronger, faster-acting insecticide.
