Flies, Maggots and Mould

FlyYesterday I opened my green bin and a cloud of small flies gushed out. Eager to be free of their plastic prison they swarmed past my shoulder and hovered at shoulder height. I peered inside the bin. On top of grass cuttings lay a galia melon, shrivelled and shrouded in a foam of white fluffy mould.

The weather recently has been unseasonable warm. The decaying contents inside your bin can reach a core temperature of 70 degrees; the perfect breeding conditions for maggots. Flies are vulnerable to changing weather conditions, a small increase in temperature can lead to a rapid growth in the density of the housefly population.

The life cycle of a fly is made up of four stages; egg, larva (maggot), pupa and adult (fly). The length of this cycle is variable but in high temperatures an egg can turn into a wiggly maggot in as little as 8-16 hours. Each female fly can lay approximately 500 eggs in several batches of about 75 to 150. So before your kitchen waste makes it to the bin don’t leave it lying around uncovered. It just takes one fly to create a lot more flies.

Keeping your bin out of direct sunlight will not only help your waste to stay a bit less stinky but will slow down the fly breeding cycle. Lining your bin with newspaper will soak up the vile pungent sludge lurking at the bottom.

The majority of maggots found in wheeled bins usually originate in the kitchen. Eggs are laid on food that has been left uncovered, and this waste is then transferred to the bin where the eggs then hatch into maggots. The best method of controlling the fly population is to break the breeding cycle by limiting the areas where they may lay eggs.

Fitting an electric fly killer is an effective means of reducing the risk of contamination from flying insects.
