HELP! I lost my baby albino wesetern hognose!

[Jordy]

So my hognose is about 6 months old and I lost it yesterday.
The moment I noticed he was gone was about 6 hours after he was able to escape ( i accidentally left my cage a little bit open). When I noticed he was gone me and my family looked over the whole house from in and outside, still we have not succeeded to find him and we are afraid he is hiding in the floor or something.
I have placed multiple pinkies and water places around the house but no success yet. A day has been passed so far.
Also, I have 2 dogs but they are downstairs while the snake escaped upstairs.
Does anybody know some more tips I can use? i already checked all the warm places with no luck.
