To sanitize or not to sanitize topsoil.

I’ve finally pulled the trigger on all new adult enclosures for my snakes and am going bioactive. I have two smaller bioactive tanks set up for some toads and with those I sterilized everything. It was easy because they were small set ups.

However the snake tanks are quite a bit larger. 5’x2’x2’ being the largest and there are two of those. I simply don’t have the ability to sanitize that much top soil. Harvested wood will be sanitized though.

Anyway I’ve read opinions on both sides about whether or not to sanitize and I’m hoping some of y’all that went the non sanitized route can weigh in. Thanks in advance.
