Thermocell Max life

Per a quick google search. Pyrethrin is derived from chrysanthemum flowers, permethrin is a synthetic form of the same thing. Both are used for similar things. Allethrin is listed as one of the major ingredients. Allethrin D was not mentioned. If used INCORRECTLY ALL could be dangerous, ESPECIALLY for cats. I still have my doubts about using the homemade OR store bought inside of a tent or enclosed blind. On the other hand I wouldn't want to be in an enclosed area with someone smoking either. USE IT OR NOT at your own risk.
