Wood for enclosures ?

[Alisha OK]

Hey everyone
I just went out and found the perfect piece of basking wood on the farm, there were bugs in it and i got those out, it's baking as I type ! There is a split in the wood that I'd like to fill in so crickets can't go hide in there haha anyone know of anything safe I can fill it with for my dragon ?
Thanks a bunch

I use 100% silicone to fill my cracks for that purpose, under rocks & holes in ornaments, but you must leave it cure 24-48 hrs.

We used Wax. Filled it in to were the critters cant get in, and either can Spazz, but this is on the bottom of the wood so there wasn't a way for him to get to it any way
