I have a brick patio that has a cement top to it, and I've noticed some sort of wasp looking insect going in and out of a hole in between the bricks. It's a pretty big patio and I don't want to try to look in the hole to see if i can see the nest (and get attacked if they are aggressive wasps). Does anyone have any recommendations on how to kill them? I could buy wasp spray and spray in the hole, but not knowing where the nest is and the fact that the patio is fairly big, there's a good chance i wouldn't even hit them. Do they make wasp foggers that I could somehow pipe through that hole to get under there? I realize the patio isn't air tight so not even sure if that's a good idea either.

Could be yellowjackets if they're under an inch long (there's one that's around 2 inches long with a striped abdomen that's NOT a threat and kills cicadas). If they're yellowjackets, be careful. They're aggressive and will attack several times.

A couple creative suggestions I was given when we had this issue 3 years ago. On a cool evening (they're less active in the cool), take a bag of ice like you buy from the store and dump over the hole. Put dirt on top of it and cover it with a tarp or clear plastic and weight it down on all sides. The sun will melt the ice and smother the yellowjackets. Another suggestion was to turn a shop vac on and place the hose right by the hose. As they leave the nest, they're sucked out right up into the shop vac. Leave it on for a few hours to make sure you have all of them. I've heard success stories with that crazy idea but I'd be paranoid that I'd open up the vacuum and they'd all be waiting to go after me. Since a nest can have thousands of yellowjackets, I'm too paranoid for that idea ;)

I have wasps between my cement patio and house cement foundation. Do I just fill in the entire area in this gap with dirt? I cannot do the ice/dirt/tarp idea, as I cannot seal entry/exit access
along the entire patio.
