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).
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
