Drione Dust can take time to kill an insect. The bees that have picked up the Drione Dust from the treated holes will die, but not until the bees ingest the dust. When bees walk through a hole or land on a surface that you dusted, they pick up the dust on their bodies. Later, when they groom themselves as most insects do, they will ingest the small dust particles and die soon after. All dust products work better the less you apply. You should only apply a very thin light dusting of the material. So it can take a few hours up to 24 or so to kill them.
Drione Dust is a very safe and non-toxic product, but like any other product or cleaning chemical you need to follow the instructions and use as directed. You would want to apply the dust where you would not come into contact with it while sleeping. You would be better off purchasing one of our bed bug proof mattress encasements. Then you would not have to treat the mattress at all, once it was covered and enclosed any bed bugs that were on the mattress would not be able to get off and feed or move around.
There are many difference between Drione Dust and Suspend SC. Suspend SC is a concentrate that is mixed with water. It can be used indoors around the baseboards, cracks and crevices and/or outdoors around the perimeter of the home. It can be also be broadcast across your lawn. The residual indoors is about 90 days. The residual outdoors is about 30 days.
Drione Dust is an odorless insecticide dust. It is mainly used inside the wall voids to protect from various pests. It is effective for up to six months if left undisturbed. When applying Drione dust, here are some tips:
Drione Dust should only be applied to cracks and crevices, voids and other listed areas on the product label when it has been removed or once every 6 months (if left undisturbed). We do NOT suggest treating the appliances with the product. For more information on a successful treatment program, please review our treatment article on How to Get Rid of Roaches.
Sounds like you are off to a great start! If you are having a problem with roaches (water bugs), you should look at treating more than just the attic, especially since the roaches are coming in from the outside. We would highly suggest you look at getting one of our Roach Control Kits for indoor and home perimeter use, and a granular insecticide for long term control in the yard around the home to cut down on the numbers in your area. The Roach Kits provide you with all the products you need to effectively and efficiently get rid of the infestation at its source rather than just where you see them, and by purchasing them in our kit rather than separately you save money as we have discounted these items. Please feel free to contact us if you have any questions.
