How do I get rid of hornets in my garden?

Question

Are they eating my vegetables?

There are three little holes in the ground. I know they're hornets, because one of the biggest hornets I've ever seen in my life came out of one while I was looking at them. I don't know if that means there are three nests or if it's one nest with three entrances. I also don't know how long they've been there because I water at night. That also means I don't know if I should water tonight. Help!

Answer 1

buy some of the wasp spray thats the long distance liquid. shoot it into the holes and give them a taste of neurotoxins. it will kill the hornets and the larvae in the nest.

Answer 2

it may not be exactly eco friendly, but while they are resting (at night)  you will need to pour gasoline in their nest holes. then cover the holes with a heavy duty tarp. weigh it down with boards,and/or rocks. This should suffocate them, and not let them out. in a few days- you should remove tarps, rocks etc, and dig out the nests.   -OR-  your hardware store should have a product specifically to kill "wasps & hornets" that you will spray in or onto the nests.
