Lice Treatment Questions

post #1 of 3
Thread Starter 
I have a flock of 30. About half had a few lice on them in my last inspection. Only a couple were infested. I treated everyone with a thorough DE bath which did nothing--to my disappointment. I then resorted to Permectrin ii spray. I sprayed everyone. It has been 14 days. I do not see any leftovers.

I understand that with some treatments that reapplication is needed due to the hatching eggs. I have waited until today to consider another application because the instructions clearly say not to reapply for 2 weeks due to the residual. So, are the eggs dead with this chemical? Should I reapply?

Also, how long do you pull eggs for? I know technically you do not have to, but I only use medications or chemicals as last resort for my organic flock. I am in medical treatment and would not want any outside chemicals coming in.

Lastly, I have 3 ducks that live with my flock. Should I treat them too? I do not see any signs.

Thank you!

Not sure how long to pull eggs.

Only thing I can find is not to ship swine for 5day to slaughter after treatment.

There is a customer service phone # for the manufacturer, perhaps they may be able to give you a clear answer.

My understanding is Permethrin spray and dust doesn't easily penetrate the skin to become systemic like Ivermectin does. It is considered a topical treatment. You would have to eat the Permethrin, bathe in it, or feed it to your chickens to get any substantial amount into your system or your bird's...and then it is still very low toxicity as mammals and birds eliminate it easily. It is only highly toxic to aquatic fish.

 

Unless you spray directly on the egg shell, there is no contamination to the egg. Likewise with eggs sitting in bedding with dust sprinkled. (After all, it is used as garden dust with instruction to simply wash most vegetables before eating.)

 

Just wash the eggs in case of residue on the outside shell. The insides will be fine as long as the egg didn't sit in a pool of spray (which they wouldn't have).
