This special formulation contains a combination of pyrethrins (0.1%), pyperonyl butoxide, and a carbamate type insecticide in this formulation which is particularly effective against this class of insect. The inclusion of a residual insecticide continues the killing action (in protected areas) several weeks after the nests have been sprayed. The jet stream pattern kills up to 15 feet away. Blast Out is non-conductive to 31,840 volts. It contains no chlorinated solvents or ozone depleters.
