I have been using Beekeepers for several years. Their first service was for a bees nest that was a threat to workers painting our house. The work had to stop until the nest was dealt with. Beekeepers was able to help quickly. Since then, we use them for mosquito control. Their treatment has been effective. Furthermore, they are always professional. There is advance notice of a treatment and they arrive when they say they will. They are knowledgeable and pleasant.
