Product Review (submitted on September 14, 2015):
I had previously used the 1 oz. Optimate and had excellent results. I have a lake property we 7se mostly on weekends. This product works exceptionally well. I spray inside and out, as directed in the instructions paying special attention to weep holes, eaves, window ledges, baseboards, etc. I spray once every 3 months, takes about 1.5 hours to do whole house, inside and out, and I never have a problem with any bugs, spiders, scorpions, ants, roaches, etc. I only have to use the blower to git rid of the dead bugs outside on the deck, driveway, and front patio. Great product! After it dries, no smell, no powder residue, etc. I highly recommend it. I bought the pint this time as it is more economical. I store it inside and feel it will give me 3-4 years worth of pest control.
