Methods such as pasteurisation and a variety of solutions can be employed to prevent and remove the threat of mushrooms flies.

WHAT ARE MUSHROOM FLIES?

These tiny and dark coloured creatures live very short lives. They measure between 2-8 millimetres in length and sometimes act as pollinators for plant pollen and mushroom spores. Mushroom flies are known to be weak flyers, often choosing to walk over plants and soil. They originate from various different families, which include Sciaridae, Diadocidiidae, Ditomyiidae, Keroplatidae, Bolitophilidae and Mycetophilidae.

Mushrooms flies are hardy creatures and capable of surviving cold temperatures. Female mushrooms flies can lay around 50 and up to 300 eggs into compost. These eggs then become larva, which develop into pupa and then finally reach the adult stage.

HOW DO FLIES HURT YOUR MUSHROOM GROW KIT?

If your magic mushroom grow has been hit by a mushroom fly infestation, several problems may arise. Mushroom flies and their larva will begin to feast off the compost that nourishes your mushrooms, as well as the mycelium networks underneath them. In doing so, mushroom flies may compromise optimal yields.

The regal and majestic praying mantis can also be brought into the grow space to take out the threat in their highly accurate and stealthy ways. These insects can grow quite large and impractical, however, whilst they are still babies they can serve as great bodyguards for your mushroom grow.

Predatory mites can similarly be used to control mushroom fly larvae. Predatory nematodes also attack other insects during their larval stage.

And finally, when it comes to natural predators that help tackle the potential problem of mushroom flies, parasitic wasps can be used.

HOW TO PREVENT MUSHROOM FLIES

Prevent Mushroom Flies - Coffee Grounds

Preferably, growers will aim to carry out preventative measures to avoid an infestation from taking place to begin with. Means such as coffee grounds and tobacco can be introduced into the growing space to deter these pests.

Pasteurising your choice of substrate is perhaps the most efficient way of preventing the presence of mushroom flies. This step will ensure that any pests already present in your substrate will be eliminated before cultivation even begins. To do so, preheat your oven to 93 degree Celsius. Pour some of your compost into a baking tray and use a thermometer to monitor the temperature of the middle of the soil. When the middle of the material reaches 71 degrees Celsius, let it bake for 30 minutes.
