which is best day to reapply permethrin? 7? 8? 9? 10?

[Jenbirdee]

i’m sorry but the 7 to 10 day suggestion drives me crazy trying to figure out. Should I do it on day eight should I do it on day nine should I do it on day 10 should I do it on day seven like which is the best day since the suggested period is 7 to 10 I’m guessing eight or nine would be premium may be exactly 8 1/2?

I don’t think it’s particularly critical, I applied on the 8th day.

The poultry mite lifecycle is generally 7 days. Severe infestations may require several more treatments beyond 7 days. Alot of folks forget to treat inside the coops and nest boxes as well.
