Q.If I replace the soil in my flower beds would I be rid of my annual cicada-killer infestation?
Each of the past 3 summers our near-the-front-door flower beds have been invaded by cicada-killer wasps. While I understand that they are mostly harmless, the menacing looking wasps scare my girls visitors approaching the front door. The past summers we have chemically treated the nests to kill the killers. I was thinking that I might pull out all the soil in those raised beds to get rid of any larvae before they hatch. Might that take care of the problem?

It would be easier to cover the soil with landscape fabric, then mulch. Here are more tips:
