I also have the 3/8 inch white mothlike bugs in my entire yard. Thousands of them! They seem to grow into large brown moths. I have never seen such an infestation in the past. If we leave our porch light on, you can hardly walk through the cloud of flying moths to get in the house. Is there something I can spray on my lawn to get rid of them?

Bill - Here is the answer I provided for Lynn: ...those are sod webworms, and their numbers do seem to be excessive this year! I found an article that describes their lifecycle and control methods here: http://hyg.ipm.illinois.edu/pastpest/200203f.html Hope it helps!
