Bwahahaa! Dead earwigs!
The one shallow container of vegetable oil I put in the garden last night has at least 25-30 dead earwigs in it this morning. I will be putting out a few more tonight and I think I'll try to sink them down in the mulch a bit so they're more level with the surface.
I'm curious to see if we can reduce enough of the population to save my plants this way. They've moved from decimating the turnips, kohlirabi and lettuce to gnawing on my cauliflower now. I have a few tomato plants that are trying to rally after being completely defoliated too. I hope this keeps working because I don't have any backup plants left!
