I had a homeless encampment near by. They had a mattress laying out that they would lounge on and watch my customers. I purchased a large bag of sugar from Sam's and spread it around and on their mattress. Should have seen them jump next time they got on their mattress. The ants took care of that problem.I've thought how about poison ivy juice and spray it inside the vacs as well as into the garbage cans and dumpster. Set up cameras and watch those poor saps with bare hands and arms going through all those......
Those are a JOKE! We tried them and they popped them open the next night with a prybar. The best thing you can do is don't lock the clean our doors and clean out the vacuums every day.JE Adams makes an aftermarket high security bar to cover the service door hasps as well. I hear these work great but make it a pain to check debris compartments.

We had the same problem with the vacs at our car wash and finally came up with a solution. We had tried leaving the vac bottom doors unlocked and using padlocks, but people continued to break them open and - in one case - using bolt cutters to break the padlock. At my brother's suggestion, we started using 1/4 inch bolts with nylon insert lock nuts. I was skeptical, but we haven't had any problems since making this change. Apparently, they give up after unsuccessfully trying to remove the lock nuts by hand. It's a cheap fix that worked for us.
