Description The original and still the best! This is a simple-to-use, disposable, outdoor fly trap that catches up to 20,000 flies per trap. Extremely effective, one regular trap can catch up to 20,000 flies in just 3 days.  Economical, low cost and requires no electricity.  Environmentally friendly, food-safe and disposable. Very easy to use. Flies cannot build up resistance to the trap. It’s particularly attractive to female flies which stops the reproductive cycle. This fly trap doesn’t attract bees or other insects. It can be used to attract flies from inside the house, business, farm or any other area with flies. It catches fruit flies and pesticide-resistant flies 10 times faster than alternative products. This trap can be used to prevent flies from entering your buildings. To use this trap simply fill it with water which mixes with the non-toxic powder to bait. Then hang it up 10-15 metres from the area you wish to disinfect, ideally in a sunny position as the red top fly catcher requires some warmth and sunlight to set up. The trap lasts up to 12 weeks and uses a non-toxic bait for safety.
