Wireworms

Hello
My grandfather has asked me to do some research for him. He has had wireworms get a lot of his potatoes this year. I don’t know much about the problem, but I’ve been looking for treatments for next year, and most of what I’m finding is pesticides for commercial-use or ones that are no longer legal to buy. Does anyone here have experience with wireworms or have any suggestions that I can give him? Thanks!
