Caution: For daytime and individual hornets, I learned that when you squish wasps/hornets, they release a pheromone (scent) that calls for others to come to their defense. Yikes. Put out a deep jar with honey in the bottom. The leftover wasps/hornets will catch in the bottom.
Spraying insecticide at night in their nests is a good idea.

Locate their hives, and then wait till after dark when the wasps are all inside the hives, and then spray each hive thoroughly with a good wasp and hornet spray. If you use a good wasp and hornet spray, they will all start to die immediately and you don't have to worry about them flying out of the hives and attacking you. You might want to buy more than one can of spray, depending on how many hives you have.

I need a good old home remedy for wasps. (The removing of them.)

I have information that if you hang a slice of watermelon over a bucket of water they will gorge themselves and drown. I haven't tried it yet, but I will if I have the problem again. (07/09/2008)

RE: Getting Rid of Wasps
Put Sevin dust in cans and place around area, like a deck. They are attracted to it and then go back to nests and are killed. You may see a few now and then, but it works and is non toxic to anything else. (07/13/2008)

I can't even go onto my back porch without killing at least 5-10 wasps in a half hour period. I see a lot of them are going up into the porch roof though any means they can.
