The question is – how do these features fit into your needs? To further explore your options; here are important factors and features to look into when choosing the best tool for your fly-killing mission.

  1. Killing Method. Some of the most common include disposable traps, electric zappers, sprays, and foggers. Some method requires effort and action in the killing while others are set-and-forget.
  2. Type of Premises. Is it in a more sensitive area (i.e food eatery, hospital) or can you afford to use more lethal options (i.e outdoor, in the yard).
  3. Coverage. How wide do you want the protective coverage to be? Will you need it to take down only flies hovering near you or do you have a very wide area to cover?
  4. Energy and Cost Saving. Does the product come with everything needed? Or is there a need to buy the parts separately? Is it reusable or disposable? In the long run, what parts will need replacing and will you be able to do the replacement yourself? How is it powered and what is the power consumption of the unit?
  5. Ease of Use. Most of these products have been designed for use straight from the box. If there are things to be installed or setup, it should be minimal and straightforward. It should be easy to clean and maintain. Also, check mounting options.

For a quick solution in dealing with a handful of flies indoors or outdoors, a zapper racket will do the job.

In an environment where the use of chemical or pesticide based product is not an option, consider an electronic zapper trap for indoor and the fly bait trap for outdoor application. Foggers work best in outdoor area where there’s a need for application to have a wide coverage.
