Do They Cause Damage?
Damage is limited to the piles of excavated soil near the nest entrance which can be unsightly. Their large size and sometimes large numbers can be alarming to those who are not familiar with them. As a solitary wasp they are inherently docile, and usually must be handled or stepped on to provoke a sting. As with All wasps and bees, stings can produce a life-threatening reaction in sensitive individuals.
Do I Have An Infestation?
The first indication is usually spotting the mound of excavated soil near the nest entrance. The mound is oval shaped and about 6”-8” long. Live insects may be seen flying back and forth about 2’-3’ above the lawn. Activity peaks in July and August.
What Can Masters Touch Do?
Smaller infestations can be managed by applying a treatment directly into the individual nests. Larger scale infestations may require an area broadcast treatment.
How Can You Help?
Females typically select sunny hillsides where grass is thin to construct her nest. Over seeding these areas to thicken the lawn can help make it less attractive to them.
The nest is a burrow in the ground approximately ½” in diameter and about 10” deep. 1 or 2 Cicada are placed in the burrow and she lays her egg on one of them. The larva feeds on the cicada and will overwinter in the burrow, pupate in the spring and emerge next summer as an adult.
