Bought the Hartz flea and tick foggers, set them off on Thurs night. The second I hit the button I began coughing and sneezing uncontrollably. Set off the other 3 as fast as I could hacking all the way. Left the apt and had to stand outside the door coughing/wheezing/sneezing to the point I almost peed my pants Made it to my vehicle just to continue this for another 30-40 minutes. Got over it, returned 2.5 hours later just to re-enter and immediately start it again. Didn’t even make it to the porch door 10 ft away where I stood outside hacking again for another 30 minutes. Today is Saturday and there are fleas jumping everywhere and new flea poop on my countertops etc. Had to go back out and buy Raid and did it all over again tonight…no coughing or adverse reaction and how much ya want to bet the fleas are dead? SAY NO TO HARTZ! Thankfully I bought a different brand of flea shampoo or my cat probably would be dead by now.
