Really never heard of squiiels in the drainage system but roots can be a problem...If you have the old clay style drainage pipes you will need to have Roto-Rutter or a company like that grind out the roots and stat using a product like Rid-X which helps prevent this...If squirrels are getting in your pipes then there is a bigger issue of open pipe in your line and this has to be replaced...Roto-Rutter can help in tha too, but get a bid from atleast 3 companies, the price can vary a lot
