Red mite

[Donna et]

Hi everyone
I wondered if there is a spot on treatment for red spider mite.
I have 20 bantam hens and this is the first time i have seen them. I have had them 4 years.
Thank you

Spray every bird and your entire coop today, then spray everything again in 5 days.
Continue the treatments of everything every 5 days for at least three treatments.
Mites are extremely hard to get rid of and you must not skip a treatment in order to break the life cycle.
