How We Decided

To help narrow down to the above list, we first ensured that these products excelled with the killing of a wide variety of flying insects, including disease carrying mosquitoes, flies, gnats and wasps. We also liked formulations that worked with crawling insects in addition to their flying counterparts, including ants, roaches, ticks and, on occasion, bed bugs.

We populated the above list with a variety of different formulations to suit both indoor and outdoor use, which included foggers and contact sprays, among other disbursement methods. We also preferred products that did not leave much of a chemical odor, preferring items that did not leave much of an odor at all or left behind a pleasant cinnamon or outdoor scent.

We made sure to include one formulation that was certified to be non-toxic and safe for pets and children, since many of the above products are filled with toxins. Finally, we did our research to pick out budget-friendly multipacks, some featuring as many as 12 units for one lower-than-average price.

Best Flying Insect Killer Buyer’s Guide

The Most Important Features to Consider

  1. Contact vs Residue
    Flying insect sprays come in two basic variants, contact formulas and residue formulas. Contact formulas kill on contact and do not typically leave a residue. These are especially effective against mosquitoes, wasps and hornets, though less effective against insects that tend to infest the home, such as gnats and fruit flies. Residue formulas leave behind a residue in their wake which continues killing for up to 12 weeks. These types of solutions can be perfect for flying insects that have infested your home.
  2. Wasps and Hornets
    Wasps and hornets occasionally require special care, especially if you are dealing with an infestation. Formulations that specialize in the eradication of these insects, such as our number two pick, use an innovative technique that, essentially, wraps the wasps in a type of foam, which kills them. It can do the same for their nests, making them particularly effective. Be careful when dealing with wasps and hornets.
  3. Odor
    If you are angling to use an insect spray indoors, you are going to want to make sure that the product does not leave a foul odor in its wake. To that end, many of the above items eschew chemical-based odors in favor of pleasant aromas that recall the outdoors or food ingredients, such as cloves or cinnamon. Before purchasing, make sure to read reviews and note if bad odors have been a detriment to any consumers.
