"Apples on the ground attract them big time.. "
My Grand-Daddy used to pick up pears from under the big pear trees behind the house and listen to the yellow-jackets buzzing inside.
Then, he'd find the hole they ate going in, and tap beside it. When a yellow-jacket poked out his head, Grand-Daddy would pinch the little bugger's head off and pull the rest of the body out. He did that one at a time until the buzzing stopped. "They can't get you if their stinger is still inside." he used to say... Just a game - the pear was no good.
Maybe you could kill them all that way!
But seriously - if you can find the nest, pour some gasoline down it after dark, and leave quickly. It'll kill 'em cheaper than store-bought poisons. DON'T LIGHT IT!
"DON'T LIGHT IT!"
Awwwww..Now you went and spoiled all the fun!!
