Due to liability reasons we are not able to comment on the work performed by pest control companies. We strongly urge you to contact the applicator and the local health department for more help. We have provided the product labels for both products below so you can see how they are supposed to be applied for bedbug treatments:

We recommend dusting the entry points of the nest with Delta Dust if you know where the nest is located inside the structure. Yellow Jacket treatments should always be conducted at nighttime, when the Yellow Jackets are the least active and least likely to sting. Please also wear protective clothing or a bee suit. Please read the article below for additional information on treating yellow jackets.
Depending on how heavy you apply the dust will play some part in it, but usually you can allow the dust to settle for at least a few hours and it would be fine to resume normal use of the ducts since it is covered by the sheeting.
Delta Dust Insecticide is not meant for human or animal ingestion. Per the product label, if ingested you should seek medical attention immediately.
We generally would not recommend creating new ways for bed bugs or other insects to access voids or hide by drilling holes into the walls. A remote wall void would be the last place for bed bugs to go, and they are usually only present there in cases of severe infestations that have been present and untreated for years; you would be able to see bed bugs easily in other areas of the structure. We suggest using Delta Dust or another dust such as CimeXa Dust where you fairly easily treat using a hand duster such as the Long Shot Puffer Duster. (CimeXa Dust is very successful as part of bed bug treatments and cannot break down over time.) Keep in mind that bed bugs, like other insects, wants to stay close to their food source. I recommend taking a few moments to review our Bed Bug Inspection Guide and performing a thorough inspection of the area if you believe there are still bed bugs but are having trouble locating harborage areas. You can also use monitoring tools such as ClimbUp Insect Interceptors or Trappit BB Detectors to help monitor areas where you suspect there may be insect activity.
Yes, Delta Dust Insecticide is labeled to be used along and behind baseboards, to window and door frames, corners, pipes, storage locations, attics, crawl spaces, garbage rooms, lavatories, floor drains (to sewers), entries and vestibules, offices, locker rooms, machine rooms, boiler rooms, mop closets and other areas which these pests may enter or crawl.
Delta Dust Insecticide should be applied using a dust applicator into cracks, crevices and voids only. Once the dust has been applied correctly and settled, you can open windows, turn on fans and properly ventilate the space and then it will be safe for folks to come to those areas.
The Delta Dust will work on any type of bee, but they may be further up in the void than the dust is reaching. Or they may have another exit point you can't see at the moment, or just a large colony in general. You can give it a few more weeks or potentially try a transfer spray like Phantom Aerosol which is a very slow kill but gets carried through the nest through touch a little better, in this case.
Unfortunately, no, Delta Dust Insecticide cannot be used inside of any appliances or in their motors to treat for German Cockroaches. Not only would that most likely damage the appliance, but it would also be an off label use for this product. You can use Delta Dust behind or under appliances, but you should not use it in any way that could potentially contact food or food-handling surfaces. Please refer to our Roach Control Guide for tips on how to treat for a roach infestation.
Delta Dust is a ready-to-use product out of the container: it should not be mixed with water or anything else. Delta Dust and other insecticide dusts are best applied using a hand duster such as the B&G Bulb Duster 1150. You would apply in cracks and crevices such as under baseboards, in the joints of furniture, under box springs, etc. Please take a few moments to review our Bed Bug Treatment Guide which has more details on using dust and other recommended products to eradicate a bed bug infestation.
Yes, Delta Dust Insecticide is labeled for roaches. Typically you will see better results by using additional products along side the Delta Dust. We would recommend that you use one of our Roach Control Kits to ensure that you have everything necessary, including an insecticide spray, roach bait gel, and insect growth regulator, to do a complete roach treatment. You may want to take a look at our Roach Control Guide for more information on treating and preventing this pest.
Yes, Delta Dust Insecticide would be an effective way to treat that area of the wall/ceiling where there is activity. Repeat treatments may be required. Using a B&G Bulb Duster, thoroughly dust the location of the hive, the remaining hive(comb) , any entrance points and surrounding areas where you notice activity. insects alight. To directly access the location of the hive or nest, drill a hole in the area, blow dust in and reseal. Wait 2 days before retreating if you still see activity.
The shelf life of Delta Dust Insecticide 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.
Delta Dust Insecticide can be applied in cracks, crevices, voids and other areas in the attic where insects harbor. This would be done using a hand duster like the Bellow Hand Duster.
