Perma-Guard Diatomaceous Earth

While this is a food-grade product, it is a mechanical insecticide that works by drying out insects, which can also irritate the eyes, skin, and respiratory tracts of humans and pets. We recommend keeping children and pets out of the immediate area during application and until the dust has fully settled.

Perma-Guard works through physical contact rather than chemical poisoning. The microscopic, sharp edges of the amorphous silica particles damage the insect's exoskeleton, causing them to lose moisture and dehydrate.

Yes, it is effective for outdoor use, but keep in mind that it is not rain-resistant. You will need to reapply it after it rains or if the area becomes wet, as moisture neutralizes its effectiveness.

Yes, this product is non-selective, meaning it will affect any insect that comes into contact with the dust, including beneficial pollinators. Use it carefully and avoid applying it directly to flowers or areas where bees and other helpful insects are active.

Because this is a fine powder, you will need a dedicated duster or sprayer designed for dry powders to get an even, thin coating. Avoid using a standard liquid sprayer, as the dust will clog the nozzle and fail to disperse properly.

Yes, this Perma-Guard formulation is OMRI Approved, meaning it meets the standards required for use in organic production systems.
