Wireworm Damage in Sweet Potatoes: Identification and Cultural Control Methods

Q: Could you tell me what is eating my sweet potatoes every year?

The creatures are millipedes but I think they're enjoying damage originally done by wireworms.

Wireworm control is difficult. One tip: till potato beds twice during coldest winter (Jan-March) to kill some larvae.

Another tip uses wireworms' preference for carrots. A month after planting potato slips, buy large carrots and bury one between each potato plant. Mark spots and dig carrots weekly to examine for wireworms. Knock them off, kill, and rebury carrots.
