As composting is a natural process involving natural tiny bacteria, heat and moisture it only makes sense that insects arrive too, right? Well, yes and no! If insects appear and are bothering you or disturbing, it is easy to get rid of them! Luckily, if they do appear it is rare for them to be anywhere near the inside bathroom toilet.

How they get in
Insects normally enter the system through accidental entry into your home or cottage (through a window, un-screened area, or door). They can be present in organic products (peat moss) or kitchen waste added to your system. One insect entering your toilet can multiply rapidly. Insects or eggs can be present in peat moss.

Add Diatomaceous Earth or any other organic pesticide to the system, which can be purchased from most pool supply stores and garden stores. It is a yellowish-white powder. Too add, sprinkle a generous amount of Diatomaceous Earth on top of the solid waste in your composting unit for 3-5 days in a row. The insects should disappear by day 2 or 3. House and Garden Raid or any other indoor/outdoor spray pesticide may be more effective in killing fly insects, if required. Spraying a small amount of insecticide will not harm your system, but do not add too much as it may disrupt the composting process.
