Diatomaceous Earth is a fine white powder made of the ground up fossilized remains of diatoms (a type of algae). It's 100% natural and it works because at a microscopic level the powder is very absorbent and effectively dehydrates parasites it comes into contact with causing them to shrivel up and expire. It can be used to control both internal and external parasites. Added to poultry feed - daily use can result in fewer worms.

Diatomaceous Earth can be used in your chickens dustbath if you suspect they have lice or mites. It can also be mixed with their feed - a good tip is to add a bit of vegetable oil to the layers pellets before mixing the powder in as it makes it stick to the pellets.

Diatomaceous Earth is also useful if you have a wormery, as it helps to control flies. Just add a light dusting to the top of your Hungry Bin or other wormery contents to help keep flies away.

Diatomaceous Earth is an approved E.U. Feed Additive (Silicon Dioxide) E551C and has been used for over 25 years for controlling parasites naturally.

SO good for my dog and myself ... - Eril,

Our lovely border 4 year old black Lab Holly has had 2 summers of fleas and has suffered badly. This time the vet recommended putting their powder down all over the house. This was something that I did not want to do as I live with MS and react particularly badly to chemicals. Found this product on the 'Net. Used it for Holly and noticed that it can be ingested by humans safely. Many of the symptoms that were mentioned are ones that I experience, eg tiredness, so I've been giving it a go for 3 days now and have seen a great benefit already ...


Very satisfied - Mike,

This powder is a treat to use, and very effective. This is something I would strongly recommend to everyone who keeps animals.
