Know before you buy
Yes, Harris Diatomaceous Earth is Food Grade and contains no chemical additives, making it a safe choice for home environments. However, you should avoid breathing in the dust during application, so keep pets and children out of the immediate area until the powder has settled.
Unlike chemical pesticides that target an insect's nervous system, this product works mechanically. The microscopic particles act as an abrasive that damages the insect's exoskeleton, causing them to dehydrate and die.
Yes, it is suitable for outdoor use. Keep in mind that it needs to be reapplied after rain or heavy dew, as the powder must remain dry to be effective against crawling insects.
It is specifically effective against crawling insects like ants, roaches, fleas, and ticks. It will not be effective against flying insects or pests that do not come into direct contact with the dust.
Apply a thin, visible layer in areas where insects travel, such as cracks, crevices, behind appliances, and along baseboards. Avoid creating large piles, as insects are more likely to walk through a light dusting than a thick mound.
