Use seven dust
A staff person informed me that For-mar doesn't make home visits. However, they did reccommend to purchase a ground insecticide to use on the bees nest. Follow directions carefully, you don't want unnecessary runoff. Good luck!
Have you tried pinterest? Lots of natural ways to get rid of them if they are bees. Bees are important but make sure they are not wasp. Wasp are known for taking over ground bees hives to steal there hunny and kill the bees off. Wasp are evil little things. But I have read alot of good things on pinterest that will help you.
