The mole cricket problem in South Carolina has gotten severe enough in recent years that talk of it has made the rounds with entomologists across the country. By now in mid-July, the damage gets severe but the crickets are large enough that chemical controls are not as effective. You can spot-treat with products like Ortho Bug-B-Gon Max Insect Killer for Lawns or Ortho Home Defence Max Insect Killer Granules. Youll get the best results next year if you map out the worst infestation spots in your yard this year and begin spot treating in late June or early July. It's unlikely you'll kill every last mole cricket in the yard, but you will get the numbers reduced to the point that their damage is minimal. An alternative, organic method thats not practical for most homeowners is to put a couple of pet chickens in the yard to feast on the crickets.
