If wasps have gotten into the inside of the hot tub is there someway to kill them or get them moved?

Wasps are nesting in your hot tub because there is a food source nearby. To get rid of them (you can't move them, you will have to kill them) you will need to hit them with with some type of pesticide that has an organophosphate mode of action, and a fogger. Malathion works well and is usually available in hardware and garden stores. I think that unless you already have some type of fogger, it will be cheaper to call a pest control company. To keep them out, remove food sources near the tub and seal up small openings in the tub structure. Food sources are usually some other small insect such as ants, mites and aphids that are themselfs feeding on flowering plants, mold in gutters, etc. Just rember wasps are meat eaters, and can be dangerous. The stings are not that bad unless you are allergic, in which case they can be fatal. Many people don't know if they are allergic. This answer is based on the assumption yhat you can't reach the wasps directly...if you can, just buy some wasp spray from the local grocery store, and follow through with the food source removal.
