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.
Talstar P cannot be used in any type of fogger. It must be applied with either a hand-pump sprayer, backpack sprayer, or mist blower.
Talstar is a great option for mosquito control and can be used in either a mist blower or a sprayer.
We generally recommend using a pyrethroid such as Talstar P Professional Insecticide or Permethrin SFR as a preventative treatment in late spring/summer before egg hatch to protect trees. If trees are badly infested, then they should be removed and either chipped or burned.
Keep in mind that trees which become infested with bark beetles are almost always susceptible due to some other existing weakness such as drought or disease.
