The larvae pupate, and then adults emerge from late July through mid-August. During this time the eggs for the second generation are laid. The second generation beetles emerge, mate, and fly to overwintering sites during September and October. If Ataenius infestations are studied farther south, slight variations in the cycle may be expected due to differences in climate. No insecticide has a general Federal registration that specifically offers control of Ataenius white grubs.
Some states do have state registrations of certain insecticides.
The performance of pesticides registered for the control of white grubs is variable depending on the insecticide's toxicity to Ataenius and the tendency of the insecticide to become bound up with thatch or to be neutralized by alkaline water. Watering the turf both before and immediately after the insecticide application improves results. For chemical control of Ataenius , consult the state extension insect control recommendations.
