ULV, Thermal or Propane Foggers produce micro droplets that are much smaller in size than the size droplets of a mist blower or handpump sprayer. Fogging tends to move and drift further than a mist due to the droplets being smaller in size. A lot of fogging solutions require the use of kerosene or oil in the mixture which can potentially damage surfaces and often have a strong smell. Fogging Solutions only provide immediate kill and may last anywhere from a few hours to 1-2 days.
Handpump sprayers, backpack sprayers, and mist blowers allow applicators to use microencapsulated insecticides for longer residual outdoors. Using freshwater for mixed solutions allows for applications to be virtually odorless and will not stain or leave an unpleasant scent. Sprayers and mist blowers offer the option of tank mixing other class insecticides for longer and better control.
For example, if treating heavy mosquito populations, we would recommend using 3 products. Talstar P (residual insecticide) with ExciteR (pyrethrin/synergist/knockdown) and Insect Growth Regulator (stops the growth cycle of juvenile insects). These 3 products can be tank mixed in the same tank and applied all at the same time.
Wasp Freeze is a product that will kill wasps if they are sprayed mid-air; however for long-term results, it works best on exposed nests that you can spray directly. If you see where they are entering, we recommned that you use a hand duster and apply a dust such as Tempo dust to the holes where the wasps are going in and out. The dust will help eliminate the wasps in the nest and any other wasps returning to the nest. Tempo dust will stay effective for several months as long as it is dry. After dusting in the void where the wasps have a built a nest you can try spraying the siding with a product such as Talstar P. You can spray once a month and any wasp that lands on treated areas will be eliminated within about 24 hours which should stop new wasps from being able to build a nest.
