Emptying the bin is only the first step
A kitchen compost caddy can hold the damp food residue that small flies seek. Replacing the liner may leave enough material beneath the rim for the problem to continue.
Start by removing the contents, cleaning the container, and checking nearby sources. Trapping adults alone will not remove residue where immature flies may develop.
Check whether the caddy is really the source
Watch where flies gather before moving the bin. Check the lid seam, handle attachments, liner folds, and any liquid underneath.
Small flies can look similar. Activity around scraps may suggest fruit-associated flies, but appearance and location alone do not establish an identification.
Also inspect overripe produce, recycling, sink strainers, damp mops, and forgotten food. For sink-side activity, read our drain fly guide.
Wash the parts a new liner cannot fix
Transfer scraps into the appropriate outdoor collection or compost system according to local guidance. Remove the liner and inspect the base for leaks.
Wash the caddy and removable lid parts with detergent and water, following the manufacturer's instructions. Brush accessible seams and let everything dry before reassembly.
Wipe the shelf or floor beneath the bin. Clean nearby cabinet edges and replace damaged liners that allow liquid to pool.
Never mix cleaning products. Avoid pouring pesticides into the caddy or compost, and do not treat food scraps with an insecticide.
Change the storage routine
Keep the lid closed between uses and empty the caddy before scraps become a persistent attraction. Shorten the interval during warm weather or when you add juicy produce.
A smaller container can make frequent emptying easier. If practical, keep suitable scraps in a sealed freezer container until collection day, with clear labeling and separation from ready-to-eat food.
Follow your collection program's rules for liners and acceptable materials. Do not assume every compostable bag is accepted locally.
Use adult traps as a supporting tool
Choose a trap intended for the insect you are dealing with. A fly strip may catch some adult flies but cannot clean the caddy or resolve every type of small-fly problem.
If you use Sulguy Fly Strips Glue Traps, follow the placement instructions. Keep strips away from exposed food, preparation surfaces, children, pets, and routine head-level traffic.
Our fly-strip placement guide explains how to think through a suitable location.
Track whether activity is declining
Record sightings in the same area each day after cleaning. If the bin stays clean but flies continue, expand the search rather than adding more traps around food.
Check behind appliances, under recycling bins, and around inaccessible leaks. Persistent activity or an unclear identification is a good reason to consult a qualified pest professional.
