Tortoise-sitting

Howdy

Have a relative in medical care, I'm trying to look after tortoises. One's a larger Sulcata, the smaller is maybe a Russian. They each have their own box.

Please understand I know next to nothing about tortoises, and sincerely hope to relinquish care back to the owner as soon as medically feasible.

Considering temporarily relocating to my house, but I don't want to disturb the totes and lamps where they live now. I would have done this already but I'm worried about temperature.

Reasonably - what would be recommended for temporary housing (and warming?) I've seen some nice items on Amazon, but we're probably talking 8 weeks or less, so budget makes sense.

Also - I've noticed a few very tiny flying bugs near one of their current containers. I don't expect that's normal.

Advice / recommendations?
