What time of year do you treat lace bugs?

What kills lace bugs?
For adult lace bugs, recommended spray insecticides include acephate, bifenthrin, lambda cyhalothrin, malathion, and cyfluthrin. Acephate may give the best control, as this insecticide is a foliar systemic that will move through the leaves to kill the lace bugs on the undersides of the leaves.

How do you treat lace bug infestation?

Are lace bugs seasonal?
Lace bugs have two generations per growing season in Minnesota. They live through the winter, as adults on or near their host plants. They can be found in bark crevices and under leaves and other debris on the ground next to these plants. In the spring, adults fly to plants and feed on newly-expanding leaves.
What do lace bugs eat?

What does a lacewing bite look like?
A slight prick, followed by a red, itchy bump — similar to a mosquito bite — is the result of a bite. The itch comes from the bug’s caustic saliva. Discomfort and the raised bump usually fade in less than 24 hours, and no treatment is necessary. Bites from lacewing larvae are a nuisance rather than a danger.
