Wasp and hornets help

[luckycluk]

We finally got our chicken coop ready after giving our flock away 3yrs ago. My 12 or old granddaughter wants us to start our flock back up. I had health problems and gave my flock away . There was 4 wasp nests we got rid of by spraying them then knocking nests down. We washed the coop n run out well. Let it dry good and put pine chips in the coop. I noticed that wasps were coming back. How do I keep them from building more nests inside the coop n run? Any help would be greatly appreciated. We have gotten 5 mix breed dominicker/ Rhode island red cross around 18 weeks old pullets. Now that they are in the coop/enclosed run im not sure how to keep them out.
Any help i would be grateful.

If you spray just plain old soapy water into their nests, it kills them. If you see a nest being built, just whip out the spray bottle and hose em' down! The soap is toxic to them.

Hit them at night, not during the day! Permethrin spray does it too, and is okay around the chickens.

Take a cup of gasoline and throw it on their nest. Any you hit will drop like a stone and any that are close to hatching will try to escape but the gas kills them in seconds. The gas evaporates in minutes so there is no fire hazard.
