As the name implies, a cicada killer is a wasp that kills cicadas. They use their stingers to paralyze unsuspecting cicada prey and serve them to their babies as their next meal. Cicada killer wasps are also commonly referred to as digger wasps because they burrow into the ground to build their homes. Their burrows look like a cylindrical hole, about ½ inch in diameter, but they can be around ten to fifteen inches deep. The multiple chambers connect underground and can form roughly 70 inches of tunnels. The females dig the tunnels and lay their eggs in the chambers.
Cicada killers may get rid of cicadas from your garden, but if they are not stopped early on, your plants will have a difficult time growing beneath the surface of the soil. You will also have a wasp infestation. They often burrow in sandy spots and sparse areas of your lawn. To hunt, they seek out sunny spots near the trees where the cicadas live. If you see a cicada killer wasp or find their burrow holes around your yard or garden, you may want to create a safe plan to kill the cicada killers before they do too much damage.
