The stuff I use is made by Bonide. It comes in a metal can with a sprayer. It's not really aerosal, more of a spray. This stuff works GREAT, kills them within 5 seconds of spraying them. They will hit the ground when sprayed and be dead 4 seconds later.
Here's what they say about it: Triple action (.1% Tetramethrin + .25% Permethrin + .5% Piperonyl Butoxide formula) provides instant knock down, quick kill and residual action that takes out the entire nest and prevents re-nesting. Jet spray shoots 20 ft. Oil based. No CFC’s. Dielectric breakdown (non-conductive up to 47,300 volts).
