Imidacloprid Gel

What are the harmful health side effects of a pest control gel containing Imidacloprid? Our building is trying to rid a build up of pests & is opting this gel as a pest control alternative to Boric acid dust spray & DRIONE® INSECTICIDE DUST. Which is less toxic? Thank you Lada

Pesticides in a gel formulation are generally considered safer and more effective because an exact amount can be placed in the exact location where it will be effective. This can be more difficult  with dust formulations.  If gels are applied according to label directions by a licensed professional and all precautions are followed there will be no risk to humans or pets. In Canada the targeted pest must be listed on the label of the registered pesticide used for control. Imidacloprid is highly toxic to bees but gels are applied indoors where there are no bees. The active ingredients in Drione dust are pyrethrin, piperonyl butoxide, and amorphous silica. Boric acid is mistakenly considered a safe pesticide but it can be highly toxic if ingested or inhaled. The manufactures’ safety data sheets (MSDS) should be used to determine the toxicity of all pesticides.    http://www.mississaugapestcontrol.ca/MSDS/MaxforceIC_Gel_Bait_MSDS_E.pdf
