how to kill webworm MOTHS

Zone metairie, louisiana zone 9 | Anonymous added on September 25, 2017 | Answered

I do have those webworm moths. i have treated my lawn for the larvae and i think i am succeeding as i dont have appreciable grass loss. I however want to kill the moths themselves. there are literally hundreds on my property. They are in the shrubs and the grass and i want them dead. i have sprayed via attaching to hose - sevin liquid, malathion and many other products. None have done a thing, i just get more and more moths. what can i use to really kill them?

I am not sure how to kill the adult moths successfully, since they are known to be good at hiding themselves and avoiding pesticide sprays. But I think the adults have short lifespans. I think the best strategy is to focus on getting rid of the larvae, which will prevent any more adults from appearing. Since the larvae are able to overwinter in your lawn, try to kill the last generation of larvae that hatches in fall. Here is more information:
