What do I do about flies in my wormery?

With regard to flies, you need to keep your food waste covered up. All flies lay their eggs on the surface of the food waste, but will not burrow. Make sure that you keep your moisture mat in place at all times (or you can use clean newspaper) to restrict access. In addition, you will need to keep any kitchen collecting bin (if you have one) covered, otherwise it is likely that you will transfer fly eggs into your wormery.

To break the cycle you can cover the top of the food waste in your wormery with a thin layer of garden soil or clean newspaper and refrain from adding waste for 2-3 weeks.

Flies prefer acidic conditions, so it is important to sprinkle a handful of the anti-acid lime mix over the surface of the food waste on a regular basis, for example, once a week. You are trying to achieve as neutral a pH level as possible so it is important to use equal quantities on a regular basis.

The other fantastic product for sorting out flies is DE Powder which is available on our website. It's non-toxic organic powder that helps control all crawling insects including flies bed bugs, fleas and ants.

The powder works by cutting the exoskeleton of the insect and killing it via dehydration.
