Help with Chicken Lice, tried Elector PSP

[lolobearleo]

Hi there!

I have 43 chickens total, 9 of whom are from my original flock and are about 1 1/2 years old. All 9 of them have what I'm 99% sure is chicken lice. I haven't seen the lice per say but all of them have the eggs around their vents. I found a picture online and am attaching for reference, this isn't my hen but this looks exactly the same.

My husband and I did Elector PSP in a pump spray bottle (like you spray weed solutions, attached a photo, not the same exact one but that style) and did the recommended dosage. We did all 43 birds to be safe and cleaned out the bedding and sprayed the two coops thoroughly. We did this all a week ago. We just checked one of the hens and she still has a ton of lice eggs around her vent area.

What should we do? Thank you for the help!

Those are like mite eggs, they won't come off right away

Should we wait then at this point? I read that elector PSP kills lice and the eggs. Do the eggs stick around for a while and then eventually fall off? Thanks for any help .

They're more or less glued on, they should fall off eventually.
