How do I get rid of hornets and wasps?
Answers:
We use water with dishwashing soap disolved in it (3 parts water to 1 part dishwashing liquid). Stir but do not shake - you want a stream, not a froth when you spray it. Use a strong spray bottle (we use a Lysol Kitchen Cleaner bottle) for indoor use or pump type yard sprayer for hitting outdoor nests. You can get the pump sprayer at a yard or hardware store
How it works:
The soapy water coats their abdomen and prevents them from breathing through their spiracles. My husband does the ones outdoors - 'me' too chicken. LOL. But I get the ones that get indoors. We had tons of them in the summer the first few years we lived here because they were building nests in the attic and finding their way directly from there to inside the house. At the time, our youngest was only a toddler so we were very grateful to have a non-insecticide means to drop them and kill them fast.
A direct spray will drop one immediately to the ground. Once there they can walk for about 5 to 10 seconds. Then they will start to curl head to tail and die. It all takes no more than about 15 seconds.
One warning. We have noticed that very late in the summer, it typically takes up to 25 to 30 seconds to kill them. We haven't figured out why that season entends their ability to survive a direct hit - maybe their larger body size then.
Other answers:
hit the wall with a stick and wait for them to attack, then you can see where they are coming from.

Spray them w/ hairspray. Kills 'em.
wasp and hornet killer will work. If worst comes to worst call the pros to come out.
Observe them and follow them. Eventually you will see where they enter into their nest. Here in Italy, they use smoke to get them out then put some sticky sap in the hole so they get stuck in it and die. That way, no dangerous poisons! Good Luck!
the best is the pesticide foam. find the nest. then wait till dark and they go to sleep. just spray the stuff into the nest. it foams up like shaving cream, preenting them from escaping and kills the whole nest in seconds. you can but the stuff at wal mart or a building centre. if the nests are underground and you see the little holes just bury them. they'll be trapped and die.
