Wasps

[GN]

I am having trouble with wasps coming in the house. I plugged the gap where I think they been coming threw. Do they leave a trail for others to follow? Killed 8 in the last 2 days.

Simple solution:
1: Take a small coke bottle or similar beverage container.
2: cut the top off just where the cone/taper ends
3: add an inch or so of apple juice, coke, orange juice, etc. in the bottle. Anything with a boatload of sugar in it should work. Meat, in particular bad meat, will work in late summer as the queens will need proteins for their hibernation.
4: turn the aforementioned cone upside down and place it in the bottle. There should be a small distance between the "muzzle" of the cone and the surface of your chosen liquid.
5: tape the cone to the bottle.
6: place in an area where you want some privacy from our persistent little buzzing friends.

Works wonders, they walk right down the funnel  to drink and 90% of them can't find their way out afterwards. Be sure to empty this thing on a regular basis as the dying/dead wasps emit certain pheromones intended to keep their sisters from meeting the same fate.
Built a pair of these and placed them on the porch, had to empty them on an almost daily basis during high summer.

Interesting, I'll have to give that a try.

To get rid of the wasp problem you'd need to find the nest and kill it from the inside.
Blocking an entry won't keep them out of your house. Wasp traps like descibed above is a good way to keep them away.
They sell biocidal products (powder) that the wasps take inside their nest.
You need to do this by evening twilight. Wasp can use their pheromones to alert the others.

Oooo! Big word! Not used to seeing those around here.

Sounds like a teramorphous comment to me....

This trick really works.  I put these traps out every year.

unless Bull is purposely tergiversating.
