Diatomaceous Earth Food Grade (DE) to kill fleas is a very effective way to get rid of fleas and ticks that are on your household pets. This method of removing fleas will also work on pets outdoors, but you must be sure it doesn’t get wet. Diatomaceous Earth Food Grade can kill fleas instantly by taking away the natural oils from their body. The flea will dry up and die due to dehydration.
Naturally, this is a pleasant way of killing pests compared to other methods like sprays or wearing toxic pyrethrin-based clothes to bed. Diatomaceous earth food grade is the most effective method for killing fleas on pets. The fleas lose their protective outer shell, dehydrate and die. This process is virtually painless for your pet.
Fleas are nocturnal. While you are sleeping they make the most of your dog or cat. They secrete saliva into their host’s skin which induces paralysis in them so they get free reign over the host’s body. It is this saliva that toxins enter their bloodstream and weaken their immune system, making it easier to transmit diseases such as FIV (feline immunodeficiency virus) or FeLV (feline leukemia virus.) Diatomaceous Earth Food Grade is a good alternative flea control treatment for cats & dogs. It breaks down the exoskeleton of pests, which dehydrates and eventually kills fleas, and ticks and prevents larvae from developing into adults.
Does Diatomaceous Earth Kill Fleas?
The answer to that question is YES. Diatomaceous earth is a non-toxic product and it’s made from the fossilized skeletal remains of diatoms, tiny aquatic organisms. Because it’s made from natural ingredients, it has no effect on humans or other animals.
Diatomaceous earth works by cutting the exoskeleton of pests like fleas and ticks which dehydrates them so they die. When you apply DE powder around your home, it becomes an abrasive surface that can cut through their exoskeletons causing their death without harming you or your pets.
What You Need to Know About Food Grade DE
Food grade DE is a naturally occurring, non-toxic substance made from the fossilized remains of diatoms (tiny algae). These organisms have been around for millions of years, and their silica skeletons were preserved on the earth when they died. It’s this silica that helps make DE such an effective natural pesticide.
There are many different ways to use DE, including:
- As a flea killer in your pet’s bedding or other areas where they spend time (such as carpets)
- In lawns to control grubs and other insects that eat grassroots
Food grade DE vs. Pool grade DE
Many people use diatomaceous earth for human or pet flea control. To be clear, there is a difference between food-grade diatomaceous earth and pool-grade diatomaceous earth. Food-grade DE is safe for both humans and pets; however, pool-grade DE is not safe for either. It’s important that you understand which type of DE you’re using so you don’t accidentally make your pet sick or yourself ill.
There are two types of DE: Food grade and pool grade. Pool grade is used to keep water clean in swimming pools, and it’s not safe for humans or pets. Food-grade DE can be found in most grocery stores and is safe for both humans and pets. The only time you should use the pool-grade type is if you want to kill fleas, ticks, and other pests outside your home, you should never put this type on your dog or cat.
Food grade DE is more expensive than pool grade (sometimes twice as much), but it’s worth it since it works better at killing fleas and ticks on your pet than regular diatomaceous earth.
How To Use DE To Kill Fleas and Other Pests
Diatomaceous earth is a natural product that is safe for humans and pets. It is made from fossilized diatoms, a type of hard-shelled algae. The fossilized remains of these diatoms have been mined and ground into a fine powder. DE acts like tiny razor blades to slice through the exoskeleton of insects, drying out their bodies while leaving them unharmed. This makes it an all-natural and humane way to kill fleas, ticks, and other pests in your home or yard without the use of harmful pesticides or chemicals.
Diatomaceous earth does not leave any harmful residues behind after use because it’s not actually a pesticide; it’s simply made up of food-grade silica (glass). This means that you can safely use it around your pets without any worry about putting them at risk for illness or poisoning, and since they’re naturally attracted to food grade DE’s chalky taste and crunchy texture while grooming themselves on its surface, they’re likely going to get plenty consumed anyway.
Is Diatomaceous Earth Safe For Humans?
Fleas are a common pest in households, particularly in the warm summer months. They can be notoriously difficult to get rid of, however, especially once they’ve taken residence in your pets’ fur or on your furniture. There are many products on the market that claim to kill fleas and other pests, but few people know about one of the oldest and most effective remedies around food-grade diatomaceous earth (DE).
Diatomaceous earth is considered safe for humans, plants, and animals. It’s not a chemical or compound like many other insecticides; it’s made from natural sedimentary mineral rock that crushes into talc-like powder with sharp edges that can pierce an insect’s waxy outer coating, resulting in its death by dehydration. Diatomaceous earth is extremely effective against flat or crawling insects such as fleas, ticks, and bed bugs. It also effectively kills cockroaches (and their eggs), silverfish, spiders, ants, and mites.
List Of Diatomaceous Earth To Kill Fleas
While there are many different types of diatomaceous earth available for sale today, only certain types are effective at killing flea infestations. It is important that you choose the right type of diatomaceous earth so that it will work effectively against these pests so that they do not return again later down the road when they feel like coming back again.
