Maggots attract flies

Tips against maggots in the organic waste bin

Maggots in the organic waste bin are a problem, especially in summer: the warmer it is, the faster the fly larvae will nest in it. Anyone who then lifts the lid of their organic waste bin will be in for a nasty surprise - maggots cavort on the organic waste and the adult flies buzz around in alarm. This is not only uncomfortable, but also unhygienic - because maggots and flies can transmit diseases and multiply at breakneck speed.

The maggots that cavort in the organic waste bin are usually the maggots of house flies, blowflies or fruit flies. The flies find perfect conditions for laying eggs and an almost paradisiacal food supply in the warm and humid organic waste bin. The digester gases and odorous substances that are produced when the organic waste is broken down attract the animals in droves. While fruit flies are mainly attracted by the alcoholic, vinegar-like smell of rotting fruit, hydrogen sulfide and butyric acid - typical vapors from rotting meat and other animal foods - magically attract the other types of flies. A fly then lays an average of 150 eggs every few days, from which maggots hatch within a very short time, which in turn develop into flies only a few days later and become sexually mature, i.e. they lay new eggs themselves - a vicious circle that must be interrupted immediately .

To combat maggots in the organic waste bin, you can either use home remedies or suitable products from specialist retailers. The maggots can be fought very well with a special organic barrel powder. High-quality organic bin powder is free from insecticides and contains only natural ingredients. It binds moisture and also prevents rot and mold. This also significantly reduces the development of unpleasant smells. In addition, the organic bin powder is very economical: one bottle is enough for an average of 800 liters of organic waste. The powder is scattered directly on the bottom of the bio bin and given over each new layer of waste.

Slaked lime or rock flour are efficient alternatives to organic bin powder. Both are available in hardware stores or in specialist gardeners and can be used to control maggots in your own organic waste bin. There are also some home remedies that can be used successfully against maggots in the organic waste bin. Table salt, for example, that is sprinkled directly on the maggots kills the animals - but it also pollutes the later compost and should therefore not be used. Vinegar water, a mixture of vinegar essence and water, also drives away the maggots. It can either be applied with a cloth or sponge on the floor, the edge and, not to forget, the inside of the lid of the compost bin, or it can be spread with a spray bottle. After that, the organic waste bin must first dry thoroughly, as moisture must be avoided in any case. Essential oils, which have been shown to have a deterrent effect on flies, are more pleasant in terms of smell. These include citrus oil, lavender oil, and tea tree oil. The scented oils are dripped onto a cotton cloth - for example an old tea towel - which in turn is then placed over the opening of the organic waste bin and held in place by the lid. The disadvantage: it has to be renewed and replaced more frequently, as the smells evaporate quickly.

Basically: Never use chemical agents to fight maggots in the organic waste bin. They can develop harmful vapors, attack the material in the organic waste bin and generally have no place in the compost. They get into the groundwater and are often still detectable in the humus that arises from the organic waste.

Unfortunately, maggots cannot be completely avoided in the organic waste bin - but precautionary measures and strong infestation can definitely be prevented.

At a glance: The most important measures against maggots in the organic waste bin
  • Only buy organic bins with a well-closing lid.
  • Place your organic waste bin in a shady and cool place.
  • Only dispose of suitable kitchen waste in your organic waste bin.
  • Empty the compost bin often.
  • Clean your organic waste bin regularly and thoroughly.
  • Keep your compost bin as dry as possible.

To prevent maggots, you should only buy organic bins that close properly. Ideally, the lid has an odor-proof and flyproof rubber seal. Existing waste bins and garbage cans for organic waste can also be retrofitted with special organic bin lids or organic filters that keep maggots away in a natural way. The right location for the organic waste bin can also prevent maggots. As a precaution, always place your organic waste bin in the shade and ideally in a cool place all year round. Correct use is also crucial: no animal products such as meat, sausage or dairy products belong in the organic waste bin. Only kitchen waste such as eggshells, leftover fruit and vegetables, coffee grounds or the like can be disposed of in it.

The waste should also never be stored in the organic waste bin for too long to make it difficult for flies to lay their eggs and to give the maggots no time to hatch. The organic waste bin should be emptied every three days at the latest, preferably daily in summer. You should also clean the organic waste bin at regular intervals - all you have to do is spray it out thoroughly with a garden hose or high-pressure cleaner. At least as important: let them dry completely before using them again. Drought is the top priority to prevent maggots in the organic waste bin. Always wrap your biowaste in newspaper and also put it on the inside of the bin, because it absorbs the moisture. Sawdust or cat litter have the same preventive effect.
