Wasps under house vinyl

Greetings RFD,

First time home owner here... its been 3 years and I'm seeing a bit of wasp activity in a gap between my vinyl and the wall.
Last week I see about 3 of them flying in and out, and today I'm seeing about 8-10...

I'm wondering if anyone has encountered this situation previously, who could share some advice?

Video of the situation shown below

These fellas are also coming out with something in their mouth... is it my house????

I'm located in the Gatineau Quebec area.

Thanks in advance!

I don't think wasps damage house materials.
You can spray waspkiller in the crack. Hopefully something that leaves residual killer so the track it into nest. When it seems they are dead, put some caulking over that gap.

Maybe test the spray will not harm/stain your vinyl siding.

I had something similar a few years ago. I set up a home-made trap right by the entrance (the cut Coke jug thing) and caught a bunch (including what looked like the queen. Then when I got bored I emptied a can of the spray into the area.

I was able to hear them inside the house and after all that, there was... silence.

Deal with it sooner than later!

Wasp Killer and then use Great Stuff to fill in voids and gaps. I just took care of one, and I think they were yellow jackets, bigger than wasps. Great stuff works instantly to block.

It's much easier to deal with it earlier than later, when its too late....it's a nightmare.

wasp killer spray in the gap. use it after sunset, when wasps are in the nest. Thereafter, seal the gap with caulking. Do not fill with urethane foam, this foam expands and can damage your vinyl siding

bad idea to use Great Stuff. This expands, and can damage the siding

The gap i had was behind siding and just under. Yes, it does expand like crazy.

There are different grades of Great Stuff...some don't expand as much.
