I will be the first to admit, when it comes to squirrels, I know very little in comparison to most everyone here, but I figured I would post this little alternative that works beautifully. I have used it on many small mammals I have had, and even my bigger mammals. In fact, I use it everywhere.

Diatomaceous earth is an amazing product. It basically acts as little shards of glass, so when bugs (pretty much everything except for earth worms) crawl through it, they die. There is no harm at all to any of the animals I have used it on. In fact, I have mixed it in my own healthy green smoothies and have consumed it, to rid of bacteria and whatnot.

There are several different types on the market, all of which pretty much differ from each other. There are ones for swimming pools, and then there are food grade. There are also ones specifically for treating bed bugs or fleas. However, I ONLY use the food grade, due to all the extra chemicals in the other types.

I bought a 24 lb bag of Red Lake Food Grade DE (it has extra calcium in it) for 12 dollars at my local Tractor Supply Co.

Basically what you want to do is you want to very lightly dust just a little bit on your squirrels (or any animal who has fleas on them). You want to make sure you keep it away from their faces, but dust them lightly with it. You may have to do this a couple of times before they are all gone depending on the severity. It's also a good idea to dust it around your house and on other animals you have.

I have also used this to get rid of bacteria and parasites from within, by mixing just a tiny tiny bit into the formula and then feeding the baby mammals. I have used this on mice, rats, rabbits, my dogs, cats, chinchilla and myself. It's a wonderful all natural way to rid of icky things you don't want inside or outside your critter!

I haven't had any issues with using this. Aside from dry hands after, this product, I swear by it. I even used it in my garden this year, and had very very little issues with bugs. For someone who is terrified of using chemicals on such sensitive animal skin...this is a godsend.

Just thought I would share!
