Delta Dust Insecticide is actually the most recommended dust for cicada killer wasps holes as it is 100% waterproof so will still work when wet.
Yes, you can apply Delta Dust Insecticide in furniture under the cushions, at furniture joints, and behind fabric tacking. We recommend using a hand duster such as the B&G Bulb Duster 1150 when applying insecticide dusts. Be sure that you do not apply dust directly on skin contact areas. Excess dust can be wiped up with a damp paper towel.
The difference between Delta Dust and Alpine Dust are the active ingredients. Delta Dust is waterproof and contains deltamethrin. Alpine is a reduced risk dinotefuran dust. Both will last many months in undisturbed voids and treat many insects.
The shelf life of Delta Dust is 3 years form purchase date. It should still be effective, as long as it was properly stored in a dry, moderate temperature area.

We do not advise using Delta Dust to target bird mites. Please review to our guide on How to Eliminate Bird Mites for further information on how to properly treat your area.
For cicada killer wasps, it is commonly recommended to use Delta Dust in each individual burrow. Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. Unfortunately, there is no fool proof way to prevent cicada killer wasps.
We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young. The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.
Delta Dust Insecticide will not react with boric acid dusts but applying too much dust to an area can make insects avoid it. If you can see the dust so can they, we would not recommend applying both in the same area.
The manufacturer recommends wearing safety goggles, chemical-resistant gloves along with long sleeves and long pants when applying Delta Dust.
