Cicada killer wasps....can they kill my plants?

Cook4July 23, 2012

We have a horrible infestation of cicada killer wasps. (At least I think they are cicada killer wasps. I've researched online and they look like ckw.)

They are burrowing down in my flower beds all around our front yard, leaving their tailings and holes. Several of the bedding plants (petunias, cosmos, etc) near the burrows have died. Now, the wasps have started burrowing near my laurel bushes and one of those is looking bad.

Are the cicada killer wasps killing my plants? For the record, we just built our house and the sod and landscaping are all just 4 months old.

On occassion, depending on how large that nest is, the tunnels might cause a, or some, plant roots to be exposed to too much air or be deprived of water which might cause the plant to die. As a rule the nests of Cicada Killers will not be harmful to plants.

Here's a good fact sheet that speaks a bit about the possibility of plant damage.

Here is a link that might be useful: click here for great information

Thanks for the information. It sounds like I might be able to"water" my way out the problem for this summer, maybe.
