What tee-jet nozzle tip would you recommend for spraying Talstar P on the eaves and siding of a home to control wasps and spiders? Also, should it be done at high or low psi from a backpack sprayer (20 or 40 psi).
Concentrates such as Talstar are not considered to be contact kills, especially for wasps and spiders. Even if you got close enough with a mist application from your backpack sprayer, the spray would not kill a wasp fast enough. They would die, but not right away. You can spray surfaces so when wasps land on the surface they will pick up the spray and die, but they will not die right away. The only product that provides fast knockdown of larger flying insects like wasps and hornets is Wasp Freeze, which comes in an aerosol can but it shoots over 15 feet so you can knock them down from a safe distance
A better option would be to use dust where you see them coming and going and as they are doing so will pick up and carry back to the nest. Tempo Dust would be great to use in a hand duster.
Any type of a fan nozzle would be best for spraying the eves. For most sprayers, you have to buy their nozzles in order to fit their sprayer.
