Did not kill wasps

I saturated the ground around the nest, and even got a few wasps, but it didn't kill them. It made my grass black, but that's all.

effective using natural ingredients

While I pride myself on minimizing my impact on my yard\'s ecosystem, I reluctantly draw the line at wasps (and mosquitoes). The W-H-Y spray uses a mixture of plant-based oils (lemongrass, clove, rosemary, geranium) to kill the wasps (spray the nest when COLD to minimize wasp activity), and the lingering fragrance seems to keep others away. The residual effect appears to last an entire season. I appreciate that the label lists the 96% Other ingredients so that there are no surprises: isopropyl alcohol (which is rubbing alcohol), isopropyl myristate (an emollient used in cosmetics and perfume), mineral oil, and nitrogen as the propellant--no synthetic insecticides. Best to store this product outside or in a garage as the fragrance is strong. Very effective spray!

Knocks them Dead!

I ditto the first review on this product - the pressure drops as the can gets lower. It works on contact to kill instantly - and penetrates the nest. It smells good, too, and I don't mind applying it near the garden.

This really works

So I found a new nest under my eaves and I sprayed (have to really shake it up for a good stream) and the adults were killed and I watched new adults flying in and they completely avoided the nest. Bingo! Would have given it 5 stars but the pressure of the stream could have been stronger.
