I have dusted a hornets nest about 3 days ago. It was high up, and uncovered under the eve, and I completely covered the honeycombs in dust. It was delta dust I purchased a year ago, and the wasps are still alive. There is NO WAY they can get n the nest without picking up the dust, yet they are alive.
The shelf life of Delta Dust is 3 years form purchase date. The delta dust should still be effective, as long as it was properly stored in a dry moderate temperature area.
