I spent 15 years in the green industry and pest control. In my time, I quickly found that bifentrin, imidicloprid, and fipronil were the best performing pesticides available. Finally getting a bifentrin product that was labeled for indoor use caught my eye, and I began using Transport. The effectiveness on typical insects is on par with many products, but its control of spiders is what initially caught my eye. FastCap is easily the best product for spiders, but Transport really surprised me. I'd go back for quarterly treatments after using it. And the amount of dead spiders had increased exponentially over the rest of the products i had been using. I even had success with roaches in conjunction with baits and IGR. Great all around product.
