Hi, we recently adopted a Russian tortoise from my friend's daughter who could not care for him. He is a little over a year old. I am quickly learning about our new pet and this forum has been very helpful. I have to admit I'm a bit overwhelmed with 3 teenagers, 3 cats, a dog and now a tort! We are in Texas (HOT & humid) and he lives in an outdoor enclosure. Recently, I have noticed more ants in his enclosure, which tend to be plentiful here this time of year (yes, we have red ants, fire ants, black ants). I need to find something that is safe to put in the enclosure because there are some tiny mounds actually in his pen. I have looked on this site, but I haven't found anything that's safe to use.
