How many feet above the ground should solid-state Army miniature (SSAM) traps be located to attract the most mosquitoes?

• A. 2
• B. 4
• C. 6
• D. 8

Answer: (C)

The idea being tested is how the height of a mosquito trap affects how many mosquitoes it catches. Mosquitoes don’t fly at random heights; they tend to move where they expect to find hosts, cues like carbon dioxide and body heat help orient them, and their typical flight height in many outdoor settings is around chest to head level for a standing person. Placing a trap at about six feet above the ground positions it where many host-seeking mosquitoes are flying, increasing the chance they encounter the trap. If the trap is too low, mosquitoes flying higher may miss it; if it’s too high, mosquitoes flying nearer the ground (including some species that bite closer to the ground) are less likely to encounter it. Six feet, roughly 1.8 meters, is a practical, general-height choice that balances interception of multiple species’ flight paths and maintains effective cue reach, which is why it’s recommended to attract the most mosquitoes.
