Y'all need to chill out.
Drew wasn't being condescending, he was just stating a fact.
I can guarantee you even if the squirrels were stung they wouldn't have too bad of a reaction. Different animals have different reactions to venoms. Humans can die if bitten by Atrax Robustus, the Sydney funnel web spider. Dogs have little to no reaction to being bitten by the spider. Squirrels can and do eat insects in nature. I can also guarantee you that squirrels have been stung by wasps in nature and don't die. Many rodents and small mammals eat stinging insects as part of their diet. It makes sense that they would build up a natural immunity towards them and their venom.
Please just take a step back from the computer and relax. We are all very willing to help you on this forum, so long as we are treated respectfully. We are not all squirrel experts as you say you are and mainly focus on insects, which are very different from mammals. It makes sense that potentially some information we give could be wrong and it really doesn't help the situation to cop an attitude with us and get angry about it. We can work together to find a suitable solution to your problem.
You can hang fly paper if they are still being relentless. The wasps will get stuck in it and die, leaving your rodents unharmed.
