Spider Dust

The best way to deal with harmful spider bites is to keep the population under control.  While most commercial insecticides will be effective for killing and repelling insects (such as brown recluse spiders and black widow spiders), they are made from manmade chemicals that can potentially harmful to humans, pets and animals, plus the effectiveness of these products typically decreases with time or wetting, increasing the chance for spider bites over time. Diatomaceous Earth does not have these limitations; its:

In the garden--great for controlling aphids, beetles, mites, leaf hoppers, and many other insects from fruits, vegetables, flowers, grains and grass, even up to the day of harvesting

On pets--good treatment for killing fleas, ticks, lice, and chiggers and for repelling them later


Spider Dust also, know as Diatomaceous Earth, Kieselgur or Diatomite, is high in silica and is found in sedimentary deposits from the Tertiary and Quaternary geological periods. It can be easily crushed into a fine, flour-like, power and is valued for is tiny particle size, the highest quality with particles less than 10 micrometers. It is very porous and therefore light in weight for its volume. Diatomaceous Earth (D.E.) is a naturally occurring product composed of the remains of microscopic diatoms deposited in ancient lake beds. Commercially it has been used in abrasive applications (e.g., polishing agent it toothpaste), water filtration (e.g., swimming pools filters), absorbent applications (e.g., spills, cat litter), agriculture (grain storage, insecticide, dewormer) and insect or pest control (home pests, pets, gardens), particularly harmful insects such as brown recluse spiders or black widow spiders with venomous spider bites. The highest quality deposits are found in Europe (Germany and the Czech Republic) and the Western United States (Colorado and Nevada).



 How Diatomaceous Earth Kills Insects

flea.jpgWhen insects, including black widow and brown recluse spiders, come in contact with diatomaceous earth, the D.E. absorbs their protective wax coating and their shells are damaged by the glassy diatoms. This combination causes them to die by dehydration. There is no survival and no built-up immunity as there is with chemical insecticides. D.E. also does not break down as chemicals do, and the more that it is used, the more insects feel unwelcome in the area and the less likely you are a loved one is to experience a spider bite.







Diatomaceous Earth to Kill Household Bugs

brown-recluse-spider-large.jpgDiatomaceous Earth is very useful around the house for control of many hard-bodies insects such as roaches, ticks, fleas, silverfish, ants, flies, crickets, brown recluse spiders and black widow spiders (with thier harmful spider bites). It can be applied as a dry dust or mixed with water at the rate of 2 oz. per quart (60 g per liter) and sprayed as a liquid:

- To be effective, it needs to be applied as a physical barrier that insects must crawl across to be damaged. Apply dust liberally around cracks and crevices, under stoves and refrigerators, and for black widow and brown recluse spiders behind furniture and in likely hiding places. Be sure to treat around sinks and drain pipes.  Such preventive measures can decrease likelihood of spider bites.

- Lightly dust areas around windowsills, doors and other places where pests may enter.

- Apply a thin layer of D.E. all over rugs and carpets to control fleas. Rake the D.E. into the fibers and leave overnight. When cleaning, do not make a special effort to remove the dust in the rug. It will continue to kill live fleas, repel others, and will deodorize the carpet.

- For even better control of flies and roaches, liberally dust the outside walls of the house, shrubbery, and outbuildings (such as barns, stables, kennels or corrals). Repeat if needed.


Diatomaceous Earth for Bedbugs

bed-bug.jpgBed Bugs are becoming endemic in various parts of the country, particularly in hotels, motels and rental units. They are very persistent and take time and consistency to rid.

- After thorough cleaning of bedding, carpet, drapery, furniture covers clothing and rest of the room; apply dust to all areas of the mattress, box springs, bed, and surrounding carpets. Also apply to closets and cracks in floors and along baseboards.  Allow two days for bugs to die.

- Vacuum all areas that were treated to remove all dead bugs, eggs and fecal material.

- Retreat all areas again, only this time; leave the dust in all areas except the sleeping surface of the bed.

- Every time you clean the room on your regular schedule, retreat all surfaces.

- Other steps include: moving the bed so it is not in contact with the wall and placing bed leg feet into smooth metal containers with Diatomaceous Earth. Treat all infected rooms in your house simultaneously.


Diatomaceous Earth for Garden Pest Control

beetles.jpgDiatomaceous Earth will help control aphids, whiteflies, beetles, mites, leaf hoppers, spiders, and many other hard-shelled insects. It can be used on any fruits, vegetables, flowers, grains and grass -- up to and including day of harvest:

- For lawns, apply 8 to 16 oz. of dust per 1000 sq. ft. of the yard. Two or three applications per year should do the job. This can be done as dry dust or as wettable powder, using suitable equipment.

- For crops and gardens, it can be applied as either a dry powder or mixed with water and sprayed. The goal is to get coverage over the entire plant, especially under the leaves. For young plants, as little as two pounds per acre may be adequate. For larger plants, 5 lb/acre is probably sufficient. With extra growth, it might be necessary to increase the amount. An examination of the leaves will tell if the leaf bottom is covered.




Diatomaceous Earth for Pets

dog-with-fleas.jpgDiatomaceous Earth is very effective against fleas, ticks, lice, and other pests on dogs, cats, poultry, and any warm-blooded livestock.

- Lightly work the material into the hair of the animal, or provide a pile or loose bag of it for animals to roll in or rub against to dust themselves. Pay strict attention to places where the animal cannot reach, such as the scalp. Dust the ears of the animal with care.

- Dust the animal's bedding and areas where the animal sleeps, as well as cracks and crevices adjacent to them. Repeat once a month or as necessary. Individual ticks observed on the animal should be dusted thoroughly.

- For confined animals infested with fleas and ticks, dust the entire area with D.E. D.E. is very absorbent and will dry out skin if used over a long period. Observe the animals’ skin carefully and discontinue use if the skin becomes excessively dry or irritated.



 CAUTION: Not all Diatomaceous Earth is Safe

Chemical and Heat Treating:

dust-mask.jpgAlthough various grades of Diatomaceous Earth can be effective for killing pests such black widow spiders, brown recluse spiders, and hobo spiders, not all are safe.  Diatomaceous Earth grades designed for swimming pool filters are processed at high temperatures (calcined), and therefore contain crystalline silica, which is not recommended.

"Both swimming pool grade and natural diatomaceous earth come from the same fossil sources, but they are processed differently. The natural grades are mined, dried, ground, sifted and bagged. The pool grade is chemically treated and partially melted and consequently contains crystalline silica which can be a respiratory hazard. Thus, it is imperative that only natural diatomaceous earth be used for insect [and black widow and brown recluse spider] control. This non-crystalline silica is not a hazard…Ingestion of diatomaceous earth is not toxic to mammals. Rats fed a daily diet containing 5% freshwater diatomaceous earth show no abnormalities after 90 days (Bertke 1964). Dairy farms sometimes feed their animals food containing 1 to 2% diatomaceous earth to control worms and other internal parasites (Allen 1972). Impoverished humans sometimes add diatomite to their baked goods in order to stretch their flour supply (Cummins 1975). It is so safe for use on food that the FDA has exempted diatomaceous earth from requirements of fixed residue levels when added to stored grain (Fed. Reg. 1961). The U.S. EPA also allows its use in food storage and processing areas (Fed. Reg. 1981)." (Excerpt from The IPM Practitioner, Monitoring the Field of Pest Management, William Quarles, Volume XIV, Number 5/6, May/June 1992).

Treated, flux-calcined, D.E. with high crystalline content creates artificially sharp microscopic sharp edges which can make it dangerous to breath. Breathing dust with crystalline silica poses a serious health hazard and increases risk for lung conditions such as silicosis. This type of Diatomaceous Earth should only be handled when where OSHA approved respirator masks.

Natural or dried Diatomaceous Earth usually contains very low amounts of crystalline silica is therefore considered safer. Because of its high absorbency, any form of Diatomaceous Earth can cause drying of the skin if handled without gloves or if it gets into the eyes. Use normal precautions.

Particle Size:

Diatomaceous earth that is used as an insecticide [including for black widow and brown recluse spiders] must be below ten microns in size to be effective, (Katz 1991a: Calvert 1930; Allen 1972). D.E. products with larger particle sizes are not recommended for insecticide use.
