Field Tests

Scientific testing has been done on the Thermacell® Mosquito Repellent unit for effectiveness against mosquitoes and other biting insects. The following entities carried out field tests on four continents in areas of high infestation:

  • The Department of Defense, Armed Forces Pest Management Board in Costa Rica
  • The Department of Defense, Walter Reed Army Institute of Research in Korea
  • Hacettepe University – SE Anatolia of Turkey
  • Scientific Coordination, Inc., in Maine, USA

Key Findings for Mosquitoes, Sand Flies, and No-See-Ums

  • Thermacell Mosquito Repellent is very effective at protecting people from mosquitoes, sand flies, and no-see-ums.
  • Protection extends up to 25 feet away from the unit.
  • Protection is greatest 7.5 feet away from the unit (15 feet in diameter) and the unit is 95 to 98% effective at this distance.

Key Findings for Black Flies

  • Thermacell Mosquito Repellent also works remarkably well against black flies.
  • Protection is greatest 3.75 feet away from the unit, where 79% protection was provided.
  • The test conducted by Scientific Coordination in Maine was done under windy conditions.
  • The report states that in no-wind conditions, the protection level would most likely have been higher.

Specific Findings from Field Tests

  • The Department of Defense, Costa Rica
    • “…96.7% of protection from mosquito attack, and 95.8% from culicoides attack in the Brenon area of Costa Rica.”
  • The Department of Defense, Korea
    • “Thus, the area repellent systems gave 98.6% protection from mosquito attack in the military bunkers.”
  • Hacettepe University, Turkey
    • “These results indicated that reduction in sand fly and mosquito biting rates in treated groups ranged from 87.5 to 97.7%.
