I have wasps under the siding by my front door. I've used Raid wasp spray as instructed on the can, but its not working. They seem to be pretty high up and despite spraying as far inside as I can I still can't get rid of them. I can't tell whether there is nest in there, but I did find one at the side of the house which I also need to get rid of. any suggestions?

Pour some gas in a cup and throw on the nest or at the wasp. Once it hits them they fall straight to the ground. Don't throw cup, just gas.
