A lil long review (be warned lol)
Last year, my neighbors and I had a problem with ground wasps in our front yards. We tried DIY solutions (soapy vinegar water in the holes at night, apple cider vinegar & mint spray) but nothing really worked. So we just dealt with it.
A year later (now) we're dealing with these scary wasps again and this time it seems like there are more of them and they spread across five different houses! We're on a rowhome block as many Philly neighborhoods are. Anyway, my one neighbor called a different exterminator service but the spray they used didn't seem to work as effectively. In my household, we got a recommendation from a friend to call Harpoon and we did. Quincy, the exterminator, told us over the phone that those wasps were cicada ground wasps - ugh - and said the best way was to spray inside of the holes that they dig. When they go back to the treated holes, they'll eventually die. He promised to come the next day and so he did. He gave an overall check in our backyard and front yard for nests and said he'll be back the following day to treat.
Quincy came back and took down an old wasp nest in the backyard. In the front yard, he did two treatments - one with a concentrated sprayer and another one with this high-powered ghostbusters-like backpack sprayer (or as my sister calls it, a supercharged turbo blaster) lol. He was thorough, even going on the grass spraying into holes while these things were flying around! The next morning when I left out, I saw dead wasps on the ground while some were still flying around. When I got back home from work hours later, I saw NO wasp flying around in our yard - only in the untreated yards nearby. He said to give it a few days to a week and they would be gone from our yard. Welp, I believe him already - thanks so much Quincy! read more
