I laughed really hard when I read that you tried to count the roaches. Definitely something I'd try and do, too!

Do you have a picture of your composting setup?

Mice love compost piles, especially when there's meat, dairy or oily product in there...you have any of that?

Although mice and rats as well as many other types of vermin can be attracted to compost piles if they are not built correctly, in properly built compost piles they are not commonly found. The Community Gardens of New York City and Chicago have compost piles that are not attrracting mice and rats even though they are around and get into the trash that accumulates.

I don't think rodents or bugs mean that the pile isn't built correctly. Often I think undisturbed compost is simply a nice safe, warm, hidden place to find nest material and food and not be bothered by meddling humans.

Frequent flipping of the compost and/or HOT compost might be less inviting. A tight-fitting lid on the bin, as well as hardware cloth on the ground below will help repel rodents.

Do you have mice or rats in there? Flipping alone might chase little mice (worked for me), but I'd be less likely to go chasing 7 rats.

compost nerd. photos below.

still have the mice. If i can't figure out to out the mice i may have to out the compost bin.

Any help is appreciated.

what the bins look like.

The Mice are just tuned into the satellite dish watching television!!

Those bins have mouse-size holes. Get a compost bin that has screening to keep out rodents and flies, or just work the pile loose in the corner against the wall. Very nice corner for that.

My loose piles have only once shown signs of rodents nesting there. The piles do have lots of grubs, worms, snakes, and now and then an ant colony.

I live in Tucson and also had a serious cockroach problem in my compost pile. When I moved the bin and pile, I killed hundreds of the suckers. Now I put a thick layer of diatomaceous earth around the outside base of the bin, to prevent more from crawling in. If they try to crawl through the DE, they will die. When I stir the compost, the few that remained in the compost that I moved try to run out, and have to cross the DE, so those die. Now I have few or no cockroaches in the bin. I got my DE from the feed store. You need the food grade, not the pool filter kind.

If you stir the pile frequently, mice and rats won't want to live in it, either. And of course, it will compost more quickly.

I think hardware clothes & a cat is the best thing.
Nice photo, Lloyd!
I do not care what is in my pile as long as it stays out of my house/bed.
But I know they have always been there, you just could not see them, because they leave at sun raise. It is the whole circle of life thing.

Thanks for the outburst of laughter, Lloyd! Just perfect.
I've never had a rodent problem with my compost, and it's exposed. But I don't ever add meats or starches. Just UCG, fruits, veggies, etc. Is that why?

I've had the occasional rat and mouse but here are some surprises most people don't see in their composting feedstock.

Ah, Lloyd...I see why you have a problem with rodents, albeit only occasionally. You shouldn't be putting whole chickens in. Especially dressed ones.
