We want to make sure that we do not get stunned by the yellow jackets so you should wear protective clothing if possible.

Make sure you wear long trousers and a top that covers all of your skin and also some form of helmet if you have one.

Previously,  I have purchased a helmet like this one on amazon before.

2: Cut A Hole Near The Nest

Next you will need to cut a new hole near the centre of the nest.

It is important that this is a new hole and not an existing hole that the yellow jackets are actively using.

Cut the hole in the wall or roof. The hole needs to be large enough for you to spray rentokil wasp killer powder in to.

3: Make Sure They Have An Escape Route Outside

Escape Root To Outside

If possible you need to secure your building to make sure that the yellow jackets do not enter your building evacuate the nest.

If their entry point to the nest is external to your building make sure the all doors and windows to your building are closed.

If you have cut a hole internally to your building make sure the room door is closed and the window is open so the yellow jackets can fly out the window.

4: Spray Rentokill In To Hole

Before you spray Rentokil (Available on Amazon) make sure you are wearing protective gloves, I recommend leather gloves and also sure you can make a quick exit after you have sprayed the rentokil.

A yellow jacket sting will hurt a lot and you need to make sure to do everything you can to avoid this.

When you are ready spray a good amount of Rentokil into the hole you created then Retreat to a safe distance. Do not return to the hole until at least an hour has passed.

You should see yellow jackets leaving the nest area. the yellow jackets should see this as an attack on their nest and they should not return.

Over the next few days monitor how many yellow jackets are still in the nest and repeat if spraying rentokill after 2 days if there are still yellow jackets in the nest.

5: Spray Quick FreezeSpray Quick Freeze 

Spraying Rentokil should be enough to get rid of the yellow jackets out of the wall or roof, but you can also use special pest quick freeze aerosols to instantly kill yellow jackets.

what you need to do is drill a few holes in the wall or roof space a few metres apart.

Then spray the quick freeze into the hole for 10 to 20 seconds then cover up the hole.

This will instantly kill any yellow jackets it comes into contact with and other yellow jackets should exit the nest.
