Then, when they shrink back to normal size, they become discolored. The potatoes are still fine to eat if they are peeled.
Where do potato grubs come from?
Hatched from eggs are the larvae or white grubs. These feed on potato tubers in August and September depending on ground temperature. They overwinter deep in the soil for five to 10 months and become active again as the ground warms up in the spring then they pupate and transform into adults.

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.
What insecticide kills wireworms?
Treatments for wireworms should not be applied unless wireworms are known to be present or have caused damage in the previous season. A few insecticides (active ingredients) that may be used in home gardens for the management of wireworms include bifenthrin (3A), pyrethrins (3A), and zeta-cypermethrin (3A).
