Delta Dust can be harmful if it is ingested by animals or absorbed through the skin. Delta Dust can stay active for several months after application. We will say that most animals will not eat Delta Dust because there is nothing to attract them to the dust and it would be extremely drying to the inside of their mouths if they did try to eat it. Still, it is best to contact your veterinarian if you think your pet ingested or absorbed Delta Dust. We have linked the product label and the MSDS in our answer so that you may print them out to give your veterinarian.
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.
Yes you could use Delta Dust Insecticide inside a car, but you would want to apply it in areas that you do not come into direct contact with, such as underneath mats, in between seats, etc. It can also be applied on 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.
