For a month we tried to have regular pest control companies remove yellow jackets from a vacant house that we own. We ended up with hundreds of yellow jackets in the house, despite the dust that the other company used. The yellow jackets made a nest in a wall and the situation became dangerous. I finally called The Beekeepers. Within a week the problem was gone, the price was very reasonable, they performed a followup inspection and guarantee their work. I wish I had calledTHE BEEKEEPERS first!!
