|A successful New York bed bug exterminator shared with me these useful tips for applying diatomaceous earth.* Delta Dust is intended for application with a hand duster (Bellow duster, Centrobuld duster) with a paint brush or by other suitable means, for hiding and runaway areas and other places where insects are found.When applying, the duster should be filled only halfway – no more than two-thirds full. This allows for adequate air space to create the desired air/dust mixture prior to application. If there is too much dust in the duster, clumps of dust on treated surfaces may result, leading to over-application of the product and messy spills.*
In living areas, apply in such a manner as to avoid getting the dust/powder on exposed surfaces or introducing the material into the air. Do not inhale diatomaceous products which often contain silica. Once in your lungs it is permanent, I am told. In the home, all food processing surfaces and utensils should be covered during treatment or thoroughly washed before use. Exposed food should be covered or removed.
|* To apply insecticide directly into cracks and crevices, use a bulbous duster or other suitable equipment. Apply lightly and uniformly to infested area. Pay particular attention to: cracks and crevices, service ducts, floors and ceilings, wall voids, around electrical and telephone fittings and equipment, around water and sewer pipes, under and behind cabinets, refrigerators and sinks, around windows and door frames, along baseboards, in attics and crawl spaces. The pest control operator advised the amount to be applied will vary with the site but should usually be in the range of 2-3 grams of Delta Dust per square yard (or 0.5 lbs per 1000 square feet).
Depending on your individual situation you may want to caulk your baseboards after applying diatomaceous earth, however talk to your pest control operator because they likely are laying down chemicals at the baseboards and may not want you to caulk until after your infestation, as a future preventative measure.Always wear a mask or respirator when applying diatomaceous earth/dust/powder. Do not inhale. Do not apply where children or pets have access. Do not apply to carpets, furniture, beds or bedding or in your car.
