I was suprised to find that other products used for Drywood Termites (PREMISE Foam, Optiguard, etc) all had gone through a standard two year test to prove it killed termites. Followed by a five year study to determine the length of efficacy and effectiveness in different parts of the country. After this, the EPA issues a registration number and the product is approved by the Dept of Pesticide Regulation. The manufacturing company (Bayer, Aventis, etc) also submits toxicology/hazardous reports and all this goes on the MSDS fact sheet you can find online. What I found REALLY interesting was the "Orange Oil" bypassed this whole process. They did not have to prove it killed termites for two years and a follow up study on top of that. True...if it didn't "kill" termites, they could not market, distribute and sell the product. If you read the data...it lasts for 24 to 48 hours...that's the window of efficacy. So the real question is>>>>can this product be applied in all infested area's where termites will have contact in 24 to 48 hours? It truely may not be for all applications. Some things to consider don't you think?
