I'm starting war on a wasp nest, and have done the first drowning with wasp form aimed at spot under the roof eves. Lots of pissed off wasps are now droning.
Interested in the killing contents of the can, I've just asked uncle Google.
So in that started typing "how effective..." and google has tried to auto complete that as
"how effective is the pill" "how effective are condoms" "how effective is the coil" "how effective is the pull out method"
Lots of angsty bees worried about birds, and I'm worried about wasps :-|
