Spectrum Brands/ Chemisco/ United Industries Corp. Product- TAT Power-Jet Stream Roach spray The insect spray I purchased did NOT do what it said it would St. Louis Missouri

I purchased 2 cans of TAT Roach spray. The can says it, "Kills roaches and ants in seconds" and, "Kills on contact and keeps on killing for 12 weeks". I saw a roach on my counter, sprayed this directly on the roach and it continued to walk away. I sprayed it again and it continued to walk away. I got my spray bottle of disinfectant, used that and the roach turned over on it's back IMMEDIATELY and died. 

I had already used one entire can to create the "barrier" they claimed their product makes- around doorway, cabinet corners, baseboards. After the roach walking away as he well pleased, I am DOUBTLTFUL the barrier works at all! This is FALSE ADVERTISEMENT! I purchsed this product because my grandmother alwyas used it successfully. The first thing I noticed was there was NO odor and I thought that was a good thing.

 
I no longer have the recepit for a refund from the store I bought it from- Doody's Home Center in Bklyn NY
