Yellowjackets

we got it also this weekend. Had wasp spray in Buggie and emptied a can on them and it did not phase them.

Going out one night soon with a 2 liter bottle of diesel

Dawn dish soap mixed with water will kill them as well and will do it quickly.
Pour a 5 gallon bucket filled with water and dawn in the hole.

It will kill them all.

Good video but leave the nests up afterwards. They are territorial and usually wont build another nest next to an existing one. It has seemed to work for me.

throw a hay bale on top and set it on fire

Diatomaceous earth in the entry and exit. Or the dawn + water

Wasp spray is like 3-4 pints at the pub for them

Stick your fingers in the hole to trap them in there. They'll run out of air and suffocate.

I just cleared my front yard with them ans wasps all in my landscaping.

Got out my pressure washer and filled reservoir with dawn.

Flipped to soap setting.

Sprayed everything. Worked great.

We seriously bought a cab tractor just to avoid this. Our fields are full of them

This. Use real Dawn, not one of the knockoff brands. Mix it well, let the suds settle and let the killing begin.

I've been using Dawn Dish soap and water on multiple occasions to successfully kill yellow jacket nests in the ground. It's my go to first choice for killing yellow jacket ground nests.

However, I just ran into a situation where it didn't work. We live on a slightly to moderately sloped heavily wooded lake lot and acreage. Several years ago we cut down a large cedar tree that was mostly dead. I was walking by that area close to sundown and noticed hundreds of yellow jackets flying back into a hole approximately where the tree trunk used to be. I had it ground down several years ago and built a garden in that area. The stump is below ground level.

I knew the Yellow jacket nest was in the ground very close to the ground down stump. I figured this is a really large nest so I made up two buckets of Dawn Dish soap and water plus I put my garden hose very nearby. I waited until after dark the next day (which was last night). I put a window screen over the yellow jacket entrance hole and poured both buckets through the screen into the hole. The hole was too deep and big, likely because the stump and big roots had decomposed under ground. After pouring the solution in the hole I stuck my garden hose in it and ran it about 5 minutes. It never gushed out of the hole.

This morning I saw a good amount of yellow jackets flying in and out of the hole. I am pretty sure that the yellow jacket entrance hole was on the downhill side of the tree stump and the yellow jacket nest or at least most of it was uphill from the entrance hole, so the Dawn Soap solution was not reaching it and saturating them.

I'm definitely not digging uphill to uncover the nest. Instead I am going to buy some Bayer Delta Dust and a duster with a long spray wand. Once I get that I will wait until night again and spray the Delta dust on the ground all around the hole entrance and also about 6 or 7 good puffs of the dust directly in the hole. I'll be ready to run like hell when I am applying the dust. If any yellow jackets fly out while I am dusting them at night, I will run like Usain Bolt in the other direction. I can always go back the next night and apply more dust. Delta Dust is not impacted by rain or high humidity so it lasts a long time compared to other dust insecticides. Obviously it can wash away but enough in an underground hole and at the entrance is very lethal to Yellow jacket nests.

It might take a day or two at the most and all of the yellow jackets will be dead. I've never tried it but read and watched videos of using Delta Dust. I will always use Dawn Dish soap and water to kill yellow jacket nests, but when the nest turns out to be uphill from their entrance hole, I will follow up with Delta Dust afterwards.
