Can't use any pyrethrins because of the Ibizan Hounds.
Sight Hounds can't abide that stuff and a lot of other normally harmless chemicals....
What is lice bedding spray?
Which department would it be in?
I also have a very small piece of Hartz flea collar taped inside of their tub.
If all else fails, I'll wait a week and feed them to Leah and start over.
Keep the dog away for few days from that room. Also dont have the collar inside the tub, The mice/rats will chew it and end up dead, keep it outside to stop the spread from one tub to the next.
The lice spray is found at pharmacies in first aid usually
