Hi, this evening I went to check on my 6 year old Russian Tortoise Kiwi. I noticed on the wall there was a moving black line. Then I looked closer, ANTS!!! The ants had crawled from the window where the enclosure is under, onto its walls and into the substrate. I spot clean every 1-2 weeks and there had been some left over food. The ants were eating the food and were crawling all throughout the substrate. They were even carrying what I believe to be eggs and placing them right next to Kiwi's feeding rock. There was a huge pile of them. I lifted up the rock and there were even more ants. I immediately took Kiwi out. Then I grabbed a bowl and took the rock outside. I sprayed window cleaner onto tge walls, which kills ants, life hack. No cleaner made its way into the enclosure. I tried to get as many ants out as possible, but I'm still hesitant to put Kiwi back inside. When I built the enclosure, I put a layer of black lining around the edges and bottom. I'm worried that the ants made their way in between that and made a nest. If anyone has any information to help me out, that would be great. I really appreciate it.
