Can I spray Malathion 57% on a new lawn to control gnats?

Will it harm the grass?


Unfortunately. Malation 57% is not labeled for gnats. If you are looking for a more natural product to treat for gnats, we would recommend a product like Essentria IC3, or if not then we would recommend like Talstar P. Each of these products would also be safe for the lawn.
