Safer® Brand Diatomaceous Earth

Leave bugs dead in the dust. That’s exactly what you’ll see with Safer® Brand’s Ant and Crawling Insect Killer. And you don’t have to worry about applying chemicals to get the job done.

Kills crawling insects within 48 hours.

Once you apply Ant and Crawling Insect Killer where you have a crawling insect problem, you’ll see insect activity stop in minutes. Infestation issues in a couple of days. Dual action. Kills insects by ingestion and dehydration. You can use it inside your home or outside on patios and walkways. It lasts as long as it’s dry.

Details on how Diatomaceous Earth works to kill crawling insects.

Diatomaceous Earth (DE) is a dust-like product that contains the crushed fossilized algae (diatoms) from fresh water. These crushed diatoms feel like powder when we rub it in our hand. But it’s very sharp to insects with delicate exoskeletons. When you apply DE, dust is ingested by the crawling insect or the insect crosses through the powder. The DE will cut their exoskeleton. This causes the insect to dehydrate and die. Insects cannot develop a resistance to it since there are no chemicals to which they can build up immunity.

What type of Diatomaceous Earth is this?

Beware. Not all DE is the same. Our DE is made of Silicon Dioxide. This comes from a freshwater source. It is the same type that is used in food-grade diatomaceous earth. Other products made of Diatomite DE are made from unnatural sources.

Use DE to solve problems with crawling insects. Ants. Earwigs. Cockroaches. Silverfish. Crickets. Bedbugs. Centipedes and more.

Directions for Use:

  • INDOOR USE: Lightly coat a thin layer of dust in the areas where these pests are found or may hide such as cracks and crevices, behind and beneath stoves, refrigerators, sinks, cabinets, garbage cans, around pipes and drains, window frames, and in attics and basements. Hit insects directly where possible. Repeat treatment as necessary.
  • OUTDOOR USE: Lightly coat the areas where pests are found or may hide including windows, door frames, and sills, and outside of entrance ways. Repeat treatment as necessary.
  • For full instructions depending on indoor/outdoor use and specific plants and insects, please refer to the Instructions link to the left.

Used it for bed bugs. Caught problem early within 1 week. It works! By Ash

Used for bed bug found after hotel stay. Molted skin found in my daughters bed after she received several bites over 5 days. Bought this and laid it down after applying bed bug covers, bowls at the bottom of bed, vacuuming, taking apart, caulking, and steaming her bedframe. Spread it everywhere around her bed, floor, bowls and on bed bug covers over mattress and box spring. It works! No more bites or evidence.

fleas By woody

can i apply this onto my cat?

Response From Havahart®
Anthony : Consumer Relations Representative

Our Diatomaceous Earth should not be applied to skin or fur. Sprinkle it into cracks and crevices where pets spend a lot of time and where fleas are present in abundance.
Please feel free to contact our Consumer Relations Team at 1-855-7-ORGANIC (1-855-767-4264) with any additional questions.

Wondering By Dwopco

Can I dust my dogs with this to rid them of fleas?

Response From Havahart®
Anthony : Consumer Relations Representative

Thank you for contacting us with this question. Our Diatomaceous Earth is not meant for use directly on skin or fur, nor is it the food grade type that may be eaten. It is only meant to be applied in cracks and crevices around a pet's bedding or in rooms where they spend a lot of time and fleas are present in abundance.
Please feel free to contact our Consumer Relations Team at 1-855-7-ORGANIC (1-855-767-4264) with any additional questions.

Question By Alex

I have a bed bug problem in my bedroom. Is it safe to dust the bedroom with the diatomaceous earth right before I sleep?

Response From Havahart®
Lauren : Consumer Relations Representative

To control bed bugs we recommend the following steps:
Dismantle bed. Use Safer® Brand Diatomaceous Earth in joints, crevices and where rungs are inserted. See that all interior areas are dusted. Dust mattresses especially folds and edges. All cracks and crevices and around window openings in the bedroom should be treated.
We recommend allowing the dust to settle before allowing adults, children, and pets back into the room. Also, once the mattress is lightly dusted, place a mattress cover or fitted sheet over the mattress to create a barrier between the product to prevent skin contact.
Please feel free to contact our Consumer Relations Team at 1-855-7-ORGANIC (1-855-767-4264) with any additional questions.

Bedbug solution By bikemannc

4lbs will handle just about any 2 bedroom, 2 bath house. Getting a hand sprayer is a great and handy tool; allowing your to place or dust anywhere that's needed. If you cannot afford it use a small paint brush.

I am infested with fleas,they keep multiplying,spread your brand of diatomaceous earth all over the house,they are getting worse. By Theo

I am infested with fleas in my house, they keep multiplying even tho i spread your brand of diatomaceous earth all over the house and the basement, they are getting worse, i don't know what to do now because i can't afford an exterminator and i have pets and kids so i don't know what to do. I have waited over 48 house and still nothing. You say the stuff is going to work but its doing nothing at all. I need Help!

Response From Havahart®
Patty : Consumer Relations Representative

Hello Theo,

We apologize for this experience and would like to provide assistance.

Bedbugs, fleas, ants, or other insects that crawl through this product will die within 48 hours of contact. For fleas, thoroughly treat floor and bedding in and around pets’ sleeping quarters. Treat surrounding cracks and crevices, baseboards, carpeting, and wherever fleas are suspected. We recommend keeping the product down as long as the flea activity is seen to give them a chance to crawl through it.

Please give our Consumer Relations Team a call at 1-855-7-ORGANIC (1-855-767-4264) with additional questions.

Have fleas...Buy it!! By Byrd

Wow...It really works. Used for fleas in the yard and house. Applied and 3 days later it rained. I thought to myself that was a waste of time, but NO within a few days no more fleas jumping on my legs. I did not reapply after rain. I have hardwood floors. When treating in the house I spread on floor and waited 3 days before I cleaned DE off floor. Received item within a few days with regular shipping.
