Frequently Asked Questions

How do I keep tunneling rodents out of my compost?

We sell a soil fences/grates that are designed to keep rodents out and allow micro organisms and worms from the soil to access your bio mass to speed composting. Made for any open bottom composter. They are 32″ x 32″ and 38″ x 38″. Or you can put hardware cloth or a wire mesh underneath the composter to keep the rodents for tunneling into the composter.

A critter chewed a hole in the side of my composter, what should I do?

We sell replacment parts for the composters. Contact our customer service (512) 407-8500 or fill out the “Contact Us” form on the bottom of this page. If rodents are a problem you can wrap hardware cloth around the bottom and sides if you need. Putting the Aerobin on a solid base also prevents the rodents for getting to the bottom edge where they can start chewing.

The material in my composter is not breaking down.

When adding material to your composter, premix your brown and green material together before adding it to your composter. This way you have a diverse and balanced mix of organic material. Nitrogen rich items such as green grass clippings, coffee grounds and chicken manure can be a catayst for composting.

Can I compost human waste or dog waste?

No, the average backyard composter does not get hot enough to kill pathogens that can cause disease. Feces from grass-eating animals, such as cows, chickens, or rabbits, is ok, but it has to “cure” for several months, or they will burn your plants.

There are a lot of fruit flies/gnats in my compost is there anything I can do?

Insects in and around your compost are considered normal. The help breakdown compost. Fruit flies/gnats have a 1–3-month breeding season and are attracted to compost for a food source and breeding environment. They will disappear after that. It’s a normal part of aerobic composting. You can make the compost inaccessible to fruit flies/gnats by covering the top layer of compost with about 1″ of grass clippings or by using some old towels. Leave the cover off for 10 minutes or so to allow them to leave because they can’t access the food source.

Do I need to turn the compost?

Turning your compost is not strictly necessary; however, it will speed up the decomposition and ensure an even breakdown of material. If you have a tumbling composter like the Mr. Spin or Ms. Tumbles, rotate the tumbler a couple of times a week.

What are the GRAF composters made of?

Material is 100% recycled polypropylene (post consumer polypropylene) – High quality polypropylene that is extremely rigid and impact resistant.
