I would recommend that you deal with the ant problem- figure out where they are coming from. I occasionally have ants get into our family room where the bunnies are by our sliding glass door to outside. I just put an ant trap under the rug (so the bunnies, cats or dogs could not get to it) and it cleared the problem up.
So don’t treat the litterboxes- find out where they are coming in and develop your plan on action based on that area.

It seems to be a bad year for ants, I have them as well and used traps in the kitchen(this is where the door to the apartment is and where they were coming in), to kill them off. So far I haven’t seen nearly as many as I was in the last few weeks!

A great way to get ants to leave areas alone is take terro ant bait and place it where the buns can’t get to it – they’ll go for the terro instead. I had a HORRIBLE ant problem this year in our new house – they broke our A/C unit by building a nest, they built a nest in our mailbox (ew!), they infested the kitchen and began invading the living room and no amount of cleaning helped… but put terro outdoor baits and in door baits down and within a few weeks, no more ants \o/ and while they were eating the poison, they were leaving my animals alone.

Be careful with it though if you do try, as it is basically syrup and borax so all types of animals want to eat it if they can get to it.

We’ve had ants in the rabbit pen before. We live in such a heavily wooded area that insects are just par for the course. They were just the standard little black ants and I would suck them up with a hand vac a couple times a day. Eventually, they were gone.

Make sure all treats and dry food is completely sealed to prevent infestation. When we were having our ant issue, I had a bag of dried banana chips by the bunny pen… I thought it was sealed… well that bag filled up with ants. It was a whole lot of “ICK!”
