What happens to the chemical once it's no longer active after 90 days?
Hi, I hope you can help. a Pest control officer sprayed Tri-Die dust on two stumps in our back yard. We are now greatly regretting it. I had a few questions. 1. Can the pesticides be removed? 2. What is the typical spray radius, do I need to remove all surrounding shrubbery and soil? 3. What happens to the chemical once it's no longer active after 90 days?

I have never heard of anyone spraying TRI DIE on a tree stump. I guess it is possible, but the cost would be prohibitive and the effectiveness questionable.
I would just wash it off with a water hose or pressure sprayer. The chemical will biodegrade into the soil. There should be no worries since it is basically pyrethrum and silica (sand).
