This might be less pest control and more vengeance.
We get Japanese beetles out here. Beautiful but they decimate the garden. I have gone around with a jar of lightly soapy water and knocked the suckers into it. Then dumped that into a larger jug that I forgot on the deck in the summer sun & heat. My mom was not happy with this method.
I think this year I want to try shop vac-ing the suckers.
I can already predict my dad covering his face with his hands. My mom will probably start saying no. I think I can convince them with the satisfying sound the bugs will make as they ricochet into the dust collector.
I also have the fact that my mom used a similar method to take care of a ladybug infestation about twenty years ago.
I am almost looking forward to trying this.
