Fleas are awful, little blood sucking monsters and they can destroy your cat’s health in no time. With more cats in a home fleas can become serious disaster. They can carry worms eggs and be health hazard even for humans.
What is the problem with the commercial flea control stuff? Its pesticide and it can be a risk for developing cancer later in life.
Diatomaceous earth is pest control and although some sources claim its natural and safe, it can be a problem too.
What is Diatomaceous Earth?
Diatomaceous Earth (DE) is a powder, the microscopic remains of fossilized microorganisms. Its made of silica and its used for years as insecticide to control fleas and other insects. The insects has exoskeleton and for that reason they are susceptible to the sharp edges of the microscopic shells. Its like shards cutting through them.
Diatomaceous Earth is non-toxic to humans and animals, it can be ingested (food grade DE) and there are even some food supplements with DE. That said, it can irritate eyes or throat. Its recommended to wear face mask when applying DE. And its totally not recommending to breath these small particles as they can create some health risks. Also the DE that is used for pools is not good for flea control as its particles are even smaller and are very dangerous to breath in.
