Backfill the holes with soil and mark their locations with sticks. Before planting your potatoes, dig up the traps and pop any wireworm you find onto a bird table.
What do wireworms turn into?
Wireworms move up and down in the soil during the season depending on temperature. They prefer soil temperature to be 50 to 60oF. After wireworm achieve full maturity during the summer, they will pupate in the soil, and the pupae will transform into click beetles after a few days.

Is it OK to eat potatoes with holes?
Potatoes have small holes in their skins called “lenticels.” These are actually the orifices through which the tubers respire, or breathe. Excess moisture can cause the lenticels to swell. Then, when they shrink back to normal size, they become discolored. The potatoes are still fine to eat if they are peeled.
