Ah! I see it worked getting them in here to offer suggestions. GREAT! We got to get those baies clean! You do not have to hold the Mom to treat her.. Just catch her resting in the condo where you can quietly sneak you hand in there and squirt it quicky between her shoulders. I have to sneak up on mine while they are sleeping or they RUN!! (I swear, they can smell that stuff a mile away!)

I would change the bedding whenever you catch the Mama out of there. It'll do no good to treat anybody when they are laying in a nest of fleas.
