Could this be tubes for snake dens?

I was on an inspection the other day and a snake got into the garage (a baby one) The snake was spotted and lifted it’s head if we got near it…sorry, I don’t have any pictures of the snake (quick little guy). I saw this below a workbench in the garage. The majority of the material a spray foam to seal exterior holes, but, I am curious if the tubes could be for snakes to access their den? I saw additional holes in the backyard which also looked like snake den tubes…

Thanks in advance
