I personally do not use it at all and my dog is clear of fleas, I am not a fan of any chemical to be honest.
When I had a flea issue with my dog (many years ago) I planted penny royal mint and used that dry in beds and collars, infused made into a spray to mist them and items with, fresh wrapped into collars, rubbed over their fur, chucked into their beds etc- got rid of the fleas and I honestly have not had an issue with them since.
That was so many years ago that my youngest dog (who turned 4 last week) has actually never even experienced fleas. God help me if she does.... I will have to find some more penny royal mint to grow and use as I have moved and no longer have any.
My dog and cats used to actually lay in the mint when ever they came home from being out and about on a walk, the fleas would jump off them faster than ever! The town we lived in at the time had a whole block (the one I lived in
) that was infested thanks to one really over grown and run down hoarders property- our house ended up being the only one in the block whos pets, furniture and carpet did not have a flea problem.
Get the penny royal mint growing- It works better than any essential oil flea product I have ever tried in the past and it did not make any of my pets uncomfortable or unwell like most of the treatments do.
The treatment you mention may be ok depending on how close to your birds you use it, I am not familiar with it and I really set myself very fail safe standards to live by for my birds safety- I take no chances with him ever as I would never be able to live with myself if I harmed him even if it was accidentally...... The use of EO's is just something I read up on and decided I personally would never use around my house while my bird lives in it, just not worth the risk to me.
