Chafer Beetle Control
Lawn grubs are the larvae of various beetles that feed on your lawn's root system. This feeding will cause the grass to wilt, turn brown and eventually cause the lawn to die. Most of the time, the main visible damage isn't caused by the grubs themselves, its caused from raccoons, skunks and crows feeding on these grubs. These determined critters won't hesitate to rip up your lawn in search of their next meal. If you've seen lawns that look torn up and destroyed, that's caused by the critters digging and peeling back the turf looking for these grubs.
The key symptoms of grub invasion are irregular brown patches that will lift up easily if tugged on (resembling drought damage). These patches have had the roots severed and there is nothing to anchor the sod in place. The lawn may also have patches that have been burrowed in or been torn up by crows, skunks or raccoons feeding on grubs. The highest concentration of grubs will be found in dead turf bordering green areas.
The grub's life cycle is very simple. The grub feeds on grass roots from mid-March to mid-May, and then develops into its pupal form. The adult beetle then emerges in mid-June, mates over a two week span and retreats back into soil to lay its eggs. The grubs hatch and begin to feed in late July to August. Raccoons, skunks and crows feed on grubs, and these determined critters won't hesitate to rip up your lawn in search of their next meal. The grubs that survive will burrow below the frost line in the fall and stop feeding; however, if there is a thaw, they will resume feeding at any time, even during the winter.
Grub treatment applications can only be done in July or August to effectively control the problem. This treatment is very highly recommended to prevent serious lawn damage.
