How a Disposable Fly Trap Works

The above image shows how a  fly trap works.

A disposable fly trap basically consists of a plastic bag which contains some attractant, the attractant acts a bait that flies find irresistible. The attractants generally comprise of food and feed ingredients, and some food flavoring agents which are recognized safe.

By default the attractants are in dormant mode, to activate the attractants you need to add some water to the bag and keep it in direct sunlight. When these traps get warm in the sun, the food flavoring agents release a scent to which flies get attracted.

Tempted by the scent, flies enter the trap, are trapped inside and are drowned in the water.
