Deep litter smell?

[Ted Brown]

Best not to, can create resistance.

I would guess that creating resistance would occur through successive use through multiple generations of whatever pest one is dealing with?

Using permethrin, which I understand to be a broad spectrum pesticide, once per year to clear out any insect populations should not create this circumstance?

I am very far from being an expert and do not want to reduce the effectiveness of permethrin or any other pesticide I might choose to use.

Can anyone provide clarity here or point to some authoritive source of reference.

Thanks

In theory, @Art is correct. In practice, resistance to Permetherins has been much slower to develop than might be anticipated. Permetherins are active on the sodium channel, and its so critical to so many life functions that mutations offering Permetherin resistance but also not fatal to the lifeform are rare.

That said, spray often enough, and it will happen.

and of course, the less complex the life form, the more likely a successful mutation won't have negative consequences elsewhere - there's simply fewer elsewheres to have consequence.

Bird Mites are close enough to Scabies that I think we can draw some reasonable assumptions as to applicability of permetherin-resistant scabies-causing mites in humans studies to our birds. I treat only as needed. Not as a prophylactic.

You're probably correct, once a year might not create any resistance, but I figure why spray poison if it's not actively needed?

...but I figure why spray poison if it's not actively needed?

@U_Stormcrow makes the same point.

He also provided two authoritive sources that demonstrate resistance development through use of permethrin. They were a chore to get through, both cases cited repetitive use, I did not doubt that resistance can develop given the proper circumstances.

I will no longer use permethrin or other insecticides unless I have an infestation.

I have also completed an expanded covered and fully HC enclosed run space and no longer free range my flock.

As always I appreciate your input and guidance.

Yeah, @U_Stormcrow is good at that, I am not.

You are too kind, and more, your value to BYC is not in your ability to link to the works of others. I'm still learning.

Great discussion! Actually learning a bunch lol So I am really just asking about in the hen house. I am going to build a carolina coops knockoff and am planning a deep litter where they use the hemp and such. But would like some feedback on that as I know nothing about in the hen house. I have deep litter in the run for sure. Just with clippings and shavings.

Inside the coop where it's dry you have Deep Bedding rather than Deep Litter.

The key is to keep it DRY -- which means generous ventilation and no over-crowding.

Thank you

As @Ted Brown said, there is a difference between Deep Bedding and Deep Litter.

Here is my article on Deep Bedding: https://www.backyardchickens.com/articles/using-deep-bedding-in-a-small-coop.76343/

Both are low-maintenance if done correctly and both are problems if you have too many chickens for the amount of bedding/litter, poor ventilation, etc. My article discusses pros and cons.

Your article is very informative - thank you! I am just starting out with a fairly large (inherited) coop in a barn (13’x10’) and 12 chickens. I haven’t cleaned out the coop yet, but will once the weather warms up here. I’m also not sure about the floor (think there is some kind of mat on top of earth). I may have to install a 2x8 at the entries to prevent spillage. May I reach out to you with questions? Thank you!
