Diatomaceous Earth Lawncare and Rodent Repellant

Diatomaceous Earth Lawncare and Rodent Repellant

Diatomaceous Earth (DE) offers the most effective pest control for lawn and home without any harm to the environment. Which gives your outdoor loving dogs and cats a safe and healthy place to play, and an eviction notice to unwanted bugs and rodents. We use DE against indoor pests like the Jurassic Floridian Palmetto Bug from Hades. And termites and ants. Success with no harm, foul, or danger at all.

There are two kinds of DE on the market, Filtered Pool or Food Grade. Filtered Pool Grade should ONLY be used for pool filtrations as the heat processing creates a high level of crystalline silica, which is extremely dangerous and can seriously or fatally injure people and animals. Pool grade DE should never be used for anything except pool filtration.

Food Grade DE offers safe effective application uses for pest control when handled with a little care, as you do not want to inhale DE. It can cause respiratory irritation. Food Grade DE is a great tool for organic, safe, and earth friendly gardens, lawns, and homes. We keep a bag of Food Grade DE in the garage for outdoor needs, and a one-pound jar inside for moments of attack by those terrorist Jurassic Floridian Palmetto Bugs from Hades.

Pest Control, the DE way. DE and essential oils. Lemon lasts a little longer, peppermint is as effective. The ULTIMATE rodent repellant that doesn't hurt a rodent at all. Which leaves predators safe to eat lunch.

How to mix DE and peppermint or lemon oils. Rats, mice, and moles are no fans of these scents.

For every one cup of DE you'll need; one-eighth cup water and four drops of essential oil.
  1. Pour 1 cup (or more with above ratios in mind) into large mason or glass jar that has a sealable top.
  2. Mix oil to water in separate bowl.
  3. Pour water/oil mix over your DE slowly. As you would water to flour for dough. Stir while pouring. (DE is very powdery light. Lighter than powdered sugar. It is highly absorbent and can irritate eyes and sinuses. Use care and read and follow packaging directions.)
  4. Stir until the DE has completely absorbed and distributed the water/oil mix. It will seem crumbly.

To use your Scented DE simply sprinkle with a spoon in the areas you have rodent problems. Your oil scented DE mix won't harm rodents. They are not poisoned, just totally put out about the smell. And they will pack their bags and leave. After use, make sure you've sealed the jar to retain the mix's potency till next time.

Tips to use DE on your lawn for pest control. (Fleas, grubs, mites, larvae, etc. and so forth)

  1. Application day should be a no wind day for even application and ease.
  2. Dampen the areas of your lawn where you want to spread your DE for pest control. DE is absorbent and will stick quickly, dry fast, and begin the work of ending the bugs, slugs, etc. and so forth mucking up your yard.
  3. Wear gloves, a long sleeve shirt, eye protection and mask for application. DE is highly absorbent and light, airborne powders can irritate eyes and sinuses. (Read and follow packaging instructions. DE is very, VERY, light powdered which is why you want a day with no winds.)
  4. Using an applicator of your choice, whether a blower, or a hand wand, apply per package directions to the wet area. Spray DE powder in a thin and even coat until the entire area and surrounding perimeter sections are dusted.
  5. You'll need to reapply after heavy rain (positive point, if it rained you won't need to hose the areas of concern first)
  6. DE application should be monthly.

The most excellent side note for DE use in lawn care and pest control is the fact that secondary predators that eat bugs and rodents will not be harmed at all. No wildlife will be harmed while enjoying your yard. DE is the effective earth origin natural product that does all the good things, without harming anything.

It's one of those products companion and wild animal lovers, love.

  • Debra Bragg,

    Yes, you can use this mix around the birds, as long as the birds can’t get to it, or disturb it with their happy wing flapping. We use it in the bird room by sprinkling it along the baseboards of all four walls. Then I take a broom and sweep at an angle to push it into and under baseboard line. I sweep up the rest. (slowly of course, so as not to get all the dust flying). It doesn’t take much at all to work. If you have dogs or cats, you can’t do this because they’ll sniff it up their nose. That’s not good.

    We also go outside with unscented and heavily dust around the base of the exterior walls of the entire house. That, we’ve found, is better than trying to do anything inside. Works like a charm on ants in the birdroom. I haven’t had to do inside the birdroom since doing exterior walls.

    A trick I learned from a bug guy, any bug that ends up in the house is looking for water, first. So we started dusting the interior wall line of our faucet cabinets. Not the entire bottom of the cabinet just where the wall meets the floor. THAT was a game changer during piss ant season.

  • Roxanne Reynolds,

    Around the house. Since they need humidity to function and travel along walls we sprinkle DE under the sinks along the interior wall of the cabinets. And you can make batches of the nice smelling DE oil mix if you like that scent. It doesn’t stop it from working on roaches. We also sprinkle DE along the garage wall that joins to the house.

    We recently gutted our half bath downstairs so while we had the walls opened we dumped (I was feeling very vengeful) a nice line of DE along the bottom of the wall braces, the slab, and any horizontal wood I could find. Then we closed the wall. (Very satisfying)

    The trick of these things in the house is water/humidity. They aren’t interested in anything but that in a house. So keeping the interior of sink cabinets dusted (just along the wall, not the entire bottom, that’s not necessary) gets the job done. Garages are notorious humidity pods in TX and FL. So you could dust along all the walls and get results.

    18 Wheelers. HAHAHAHA! I was drinking coffee when I read that, and now my keyboard is, too. 

    Death to 18 Wheelers!
