We’ve just recently built an RV garage and had to bring in a lot of dirt to get it level. I started noticing something burrowing into the embankment around it the last couple of weeks. Thought it was small moles? Standing out their this morning I watched Cicadas flying in and out of the holes. Did some reading and realized they do that. I love the sound of them but am concerned at the number of them that are burrowing into this bank under my garage.
How deep do they burrow? Worried about the integrity of the foundation. Is it an issue and is there any recommended treatment to deter or kill them?
Right now I would estimate there are about 15 holes out there.
As explained in our CICADA CONTROL ARTICLE, Cicada’s will feed on the roots of trees and other plants as larvae grow up and then emerge as adults once fully mature. These adults will forage daily from exit/entrance holes that lead to their burrows or nests. Throughout the day they’ll come and go with females laying eggs at some point in the season to further populate the area.
Though I can’t say they pose a risk to the integrity of the foundation, I do know where excessive holes have led to water issues for some structures. Burrows can funnel unwanted water alongside homes and any structure with a basement could develop problems down the line should they allow these burrows to further progress. Additionally, cicadas will almost always attract CICADA KILLERS which are large wasps. These wasps generally don’t pose a hazard to people but when they start nesting in areas frequented by people, they tend to be disconcerting to say the least. Cicada Killers are quite large and intimidating.
If you decide you don’t want the cicada’s burrowing anymore or the prospect of attracting cicada killers, apply some of the BIFEN we have listed in our CICADA CONTROL PRODUCTS section. It will quickly knock them out, especially if you treat these nests directly, and the problem will be solved.
