Some of the available brands of these "essential oil" products include Avenger Natural Bug/Insect Killer, EcoSMART, Earth Harvest ICT Essential 1 and a new product  I have recently tried out with success in the vegetable garden is Nature-Cide. You can ask the pest control company to use EcoEXEMPT. It is also in this category. This new group of pest control products is just great because it totally eliminates the need for anyone to ever use a toxic chemical pesticide.
