When is the best time to apply Bifen L/P Insecticide Granules Sod Webworms?


Bifen L/P Insecticide Granules are best applied in the late afternoon or early evening when larvae are active. Granule applications also should be lightly irrigated immediately after application to wash granules off grass blades and activate the insecticide.

Sod webworms complete development, pupate and emerge as adults from mid-May to mid-June. Applications of insecticides in early to mid spring before larval activity resumes is most beneficial for control with applications every 30 days.  Please view our Sod Webworm Treatment Guide for more information.
