Lol I think a Sulcata would have to be one of those giant mundo burgers from Man vs Food. Fish and veggies are boring. ;) But NON tortoise/turtle inspired foods are better (All those who eat these poor creatures. Smh)
I can't see the pics posted. I'm basing my opinion on my knowledge Russian Tortoises. I'm sure the real experts will see this and pop their heads out of their burrows.
Bushes, fences, rock areas, tree lines, large holes in the ground, digging areas, ask neighbors...those are where I would start with. Search high and very low. Hope you get it back. I feel yeah.
Just remember to make sure whatever you use cannot hurt your animals. Plenty of stuff out there, Google is your friend but also can be your enemy. Paranoia is always my friend. Lol
Windex kills ants on the spot and can help wipe trails. No real fix. Balsamic Viniger and Lemon Juice a 50:50 ratio is known to be one of the best natural organic insecticides. I wouldn't spray it in the pen but around the entire perimeter is alright. You have to reapply appromix every 3...
