How to control Cicada Killer Bees

Post by donna1wren » Tue Feb 01, 2011 2:38 pm

I live in Lancaster County Pa. In 2009 I had a few Cicada Killer bees in my garden digging tunnels but in 2010 I had way to many. I had to stay out of parts of my garden and they just scare me.
I was thinking about putting grub killer in the areas were they dug tunnels and laid their eggs. Since the lava hibernate till spring I would work the grub killer into the soil about June1.
Do you think it would work or what do you suggest?

Grub killer will most likely not work for these wasps because, though the larvae overwinter in the ground, they are surrounded by a hard cocoon that would protect them. Their life cycle is very different from the beetle grubs which are controlled with grub killers. The best control is to dissuade them from using your garden for their nesting area. Here is a great website that has some good information about these wasps: ... ler-wasps/. There is a link near the bottom of the page with suggestions for controlling them.
In addition to these suggestions, Sevin dust can be applied in and around the entrance to their tunnels at night when they are in the burrow. When you no longer see activity at the nest, just cover the hole with a shovelful of soil.
