Since weed killer is ok, let me jump in with a question about the best flying wasp killer.
I bought 2 cans of Spectracide, an alleged instant wasp insecticide from Walmart. Total crap!! After dowsing large paper wasps, they backstroke in the puddle fer a bit, then dry off and fly away. This, despite claims of "kill on contact" and "guaranteed". Don't waste yer money.
I know from using it a previous year, Black Flag works pretty good. ACE hardware brand also is not bad. Any brands out there that are even better? Bear in mind, I want a straight stream spray so I can hit the bastids from a distance. ;)
