New Evidence Supports Use of Food Grade Diatomaceous Earth as a Solution to Pests

Harvard biologists suggest using diatomaceous earth as a natural pesticide. Chensheng Lu, an associate professor at the T.H.Chan School of Public Health, has published a study on links between the use of chemical pesticides and childhood cancer (2).

Diatomaceous earth has been shown to be effective as well as safe.

Many studies have been performed on the efficacy of diatomaceous earth in controlling pests (3). It’s even hailed as more effective than chemical pesticides (4). For this reason it’s often added to food processing facilities to ward off bugs in stored grain.

How to use diatomaceous earth to combat household pests.

Get bugs before the enter the home. Spread diatomaceous earth around the foundation of your home, if you live in a free-standing house. The tiny rough edges of the diatomaceous earth particles will actually shred the bodies of intruding bugs, according to a Tucson pest control company.

All those tiny cuts cause the bugs’ exoskeletons to dry out and they die of dehydration.

If you can’t get the bugs before they enter, get them where they live and hide. Inside the home, apply diatomaceous earth to the cracks and crevices where bugs (i.e.cockroaches) are hiding.We all suspect that household chemicals may be harmful to children. But now there’s proof that pesticides used inside the home are linked to higher rates of childhood cancer.

A new study out just this month highlights the dangers of using chemicals to fight pests such as cockroaches and ants. Published in the journal “Pediatrics”, managed by the American Academy of Pediatrics, the meta-analysis draws from 277 studies on record in the nation’s PubMed database (1).

The results showed that children who are exposed to indoor insecticides have a higher risk of hematopoietic cancers (cancer related to the blood).

Why household chemical pesticides are harmful to kids. 

Children’s immune systems are still developing and are therefore not as effective as the immune systems of adults. When kids’ immune systems encounter the chemicals present in household pest sprays, they simply cannot provide the protection kids need.

Not only that, but kids also have less fully developed detox systems. When exposed to harmful chemicals, the detox systems of adults are much more adept at flushing out toxins.

Kids, on the other hand, suffer because their detox systems are less developed and because the total effect on their bodies will be greater. Their bodies are smaller, after all, so the same amount of harmful chemicals will have a much greater effect on them than on adults.

Compare it to alcohol consumption: the effects are much stronger on smaller people.

The study recommended that parents take preventive measures to avoid their kids’ exposure to insecticides in the home. There have been other natural supplements out there (forskolin comes to mind) that are safe, and silica can also fall into that category.

So, go natural. It could help you – and your kids.
