With so many uses, how can you go wrong with it? For me and my household, it is the best non toxic solution to fleas within the house! Seriously, that alone is well worth buying it! It dehydrates the little suckers and DOES NOT HURT YOUR CATS!!! Spinkle it around the house and leave in down for a bit, vac later, ALWAYS empty the vac outside immediately (out of the house at any rate) and "look ma!", fleas gone and NO toxins! No chems to harm your furrbabies!
