That's Not An Ant Hill, It's a Digger Bee Mound in Toms River, NJ
Challenge
This homeowner in Toms River, NJ called our office after spotting multiple large anthills all over her backyard and mulch bed, so I was sent out to investigate. After a thorough inspection, I was able to determine that the "anthills" were actually digger bee mounds.
Digger bees, also called ground bees, are solitary, non-social wasps, and are about 1/4 to 1/2 of an inch in size. They tend to be most active around early to late spring and each mound is a separate, independent nest of digger bees. The females dig these half-inch to one-inch deep burrows to nest and raise their young. Their large size can be intimidating, but unless you directly grab them, they are harmless. In fact, you can walk through a field of digger bees and not get stung! However, they turn beautiful lawns into minefields.
Solution
I soaked each digger bee mound with a liquid residual application. Once the digger bees come in contact with this product, they are rapidly eliminated.
