this morning i used had a can of sevin-5 to shake my chickens to kill off the lice and mites, i used the other half in the run, with a concentration in thier favorite dust bath spots. Of course an hour later it started to rain, so now my chickens are wet(they like the rain) and everything i spread in the run has soaked in, does that make this treatment bust, or will everything still work right so long as i do it again in 10 days, and what happens to what is obsorbed into the soil???
