Hi Doreen –

Scanmask® Beneficial Nematodes are a very effective biological control for use against sod webworms. For best results, apply when young larvae are present and water the area before and after application. Nematodes do fine in higher temperatures as long as the soil doesn’t get completely dried out.

Each box of 10 million nematodes treats between 320 and 850 square feet depending on pest and level of infestation.

Good luck!
