Get Rid of Grubs from your lawns
Grubs are the larva of beetles and they are white with dark rear end and red head. Usually they have a ‘C’ shape. Beetle normally lays eggs in soil during the months of June and July and by August these eggs hatch and the larva comes out.
This larva is called grub and it will feed on your grass root and by October larva will move down to the soil. Again by January larva comes out of the soil and starts feeding on the grass roots. This will produce a brown patch in your lawn. By the month of May larva goes in to pupae stage and will emerge as beetle in June. Soon beetle will be ready to lay eggs. If the grubs are left untreated then soon they will damage your entire lawn.
Ways to Control the Grub Infestation
Control Grubs by Watering
Water the lawn thoroughly so that it will soak almost six to eight inches of soil. This will help the roots to spread deep in to the soil and thus roots grow slowly and steadily. This helps to make healthy roots and leaves which will be tough for the grubs to infest. Allow the soil to dry properly before watering it next time. If your lawn can manage drought then avoid watering the lawn in the month of July and early August as the eggs of grubs present in the soil require moisture for hatching. With out water these eggs may dry out.
Apply nematodes in your lawn using a sprayer. Nematodes are microscopic creatures that are environmental friendly and beneficial to the plants.
Nematodes will move in to the grubs and there they multiply and kill the grub. Afterwards nematodes will move out in search of another grub. Apply nematodes during the month of August when the larva is small so that you can avoid the damage to your lawns.
Over seed your garden and make a thick turf. This may help you to avoid the grub infestation. While mowing your lawn cut only the tips and never mow deeply as small grass may attract grubs. Also avoid fertilizers that are rich in nitrogen as nitrogen allows the grass to grow faster than the normal and this result in a less healthy grass. If the lawn is less healthy then it will be easy for the grubs to feed.
