frontline use

my guys have lice again by the looks of it and i am wandering if thats what is making one of my girls seem poorly again .

i did have a website that i use to get the frontline from but i cant find it but before i go hunting for it do i buy the drops or the spray { drops would be easier } .

thanks auntie , maybe it would be better for me to pick up some more diatom an poulty shield instead . i blame this weather for being them back again  . one good thing though i have never noticed anything in the house and thats jeyes completely once a week so it seems its only the girls i got to deal with , but is it ok to use diatom on the babies they must be about 11 weks old now .

i will track down the site i have used before then and order some tomorw . i got to get even with this nasties once and for all .
