Ah ha. Chickens! Now I understand. Your best long term bet is to cure the chickens of external parasites. If you’re that uncomfortable, you can bet your biddies are too, and egg production is probably down, and they are going to be susceptible to a lot of other diseases. Here’s a good, non toxic way to control external parasites in fowl. http://naturalchickenkeeping.blogspot.com/2012/12/natural-way-to-rid-chickens-of-lice.html
As for tea tree oil, go to a health food store (if one is nearby), and don’t get the cheapest oil, which is usually Now brand. You can pay a lot of cash for essential oils (such as Young Living brand), but in this case, anything in the middle price range should work. The last time I priced tea tree in a health food store, a ½ oz bottle ran around $10— $12 US. If you’re too far from a health food store, PM me, and I’ll help you buy it from a reputable source online.
This is a really strong oil. Test a little on your skin before you use it. A little goes a long way This article below says to use tea tree AND lavender, and that it’s effective with only 2% tea tree (much less than I recommended ) I’ve never used the lavender, but do what you think best.
Here’s an excerpt from this site: http://m.wikihow.com/Remove-Lice-Using-Tea-Tree-Oil 1Purchase pure tea tree oil. Tea tree oil has natural antimicrobial, anti-bacterial, anti-inflammatory, anti-fungal, and anti-viral properties.[10] Although the exact mechanisms are not yet understood, tea tree oil has been shown to be effective in killing lice nits and reducing the number of live lice. It may also have lice-repelling properties.[11]
A combination of tea tree oil and lavender oil has been shown to kill lice eggs and live lice.[12] Look for pure lavender oil.
While many shampoos and conditioners have tea tree oil in them, they are unlikely to have a high enough concentration to be effective. A minimum concentration of 2% tea tree oil is required to kill lice nits.[13]
Look for “steam-distilled” tea tree oil from the Melaleuca alternifolia tree.
Another option is to use raw unfiltered apple cider vinegar (if you can, pay the extra and get organic- it’s worth it). This article says ACV works on external parasites, but you put it in their water. http://healing ponds.com/apple-cider-vinegar-for-horses-etc/ It will help you too. I have sprayed regular grocery variety apple cider vinegar on horses to keep off flies.
I’m not sure if it would work, but you could try rubbing ACV all over your skin (like I did for my horses) to see if it discourages your little lodgers. Or try rubbing ashes all over. If it works for the chickens, it should work for you too!
PM me if I can be of encouragement to you, and let us know how it’s going please.
