Does anyone know what the shelf life of a spray can of ant and roach killer
would be? Pyrethin based. I bought a can last summer and it doesn't seem to
be very effective. Would I be better off buying non-pyrethin based products
if I want to carry over from year to year. The same goes for wasp sprays.
You certainly don't want to use a can thats not going to kill anything.


It's not very effective because pyrethin is not
very effective. Try something else.
