product that lasts outside between applications
Scorpions, spiders, cockroaches, occasional stinkbugs I would like a product that lasts as long as possible. I may need 2 different products. Live in southeastern Arizona where Sun and heat are factors during summer. We also have missions for a couple months, so I may need a different product during that time. Not worried about staining or white powder showing after application. Have 3 pet birds. Would be totally willing to spray one product that is better at killing, waiting for it to dry, then perhaps spraying another product that withstands weather and requires less frequent treatment. Or mixing 2 products if that would help. Also willing to spray one product outside and different one indoors if that would help at all. In addition, I want to mix in an igr for the roaches.
Demon Max lasts approximately 30 days outdoors. We would recommend using Suspend Polyzone if you are wanting a longer residual. It also features a proprietary polymer layer that protects the active ingredient from weather, irrigation and mechanical abrasion. The residuals outdoors and indoors is about 90 days. This can be used around the perimeter of your home and does dry clear. We would recommend not spraying this while your birds are in the area. They can return once the product dries.
A good IGR (insect growth regulator) is Gentrol IGR. It is labeled to work for up to 4 months for roaches. This can be mixed with insecticides as well in the same sprayer.
