I started my compost pile in November. It is inside of 4 wooden pallets that I attached together. Anyway, I went to turn it this weekend and noticed a ton of little, orange ants in one scoopful. They are not fire ants. I've only added shredded leaves, grass, coffee grinds, and green kitchen scraps to my pile. I don't know where they are coming from (other than maybe the pallets themselves?) as I've not added any wood to the compost pile. I poured some hot, not boiling, water on there but it didn't seem to do much to hurt them.
The interior of my pile is always over 100 degrees a few days after turning, so I thought that would not be hospitable to ants. Should I be concerned or just let it go?
Richmonder - as long as they are not fire ants, or termites, I would leave them alone. Ants are considered "beneficial insects" - some plants are pollinated by ants. They are probably enjoying the heat from the compost pile to keep their nest warm.
