Nasty wireworms

[Tokes polytunnel]

Thanks for reply! Have you heard of the use of burying a tin in the ground filled with potato and carrot peelings? Apparently this is a sort of trap that you keep emptying.
Yes, the polytunnel was put on a field that was newly ploughed.

For the future, would the no dig method combat the wireworms because you’re not turning the soil over?

P.s, if I use grow bags for this year, would they get in there to?
