Mosquitoes Are Back: I Tested 8 Repellent Methods—Here Are the 3 That Actually Work

Last Friday evening, I was reading on my balcony and got three mosquito bites on my right ankle. Three. I counted. Three bites in a row on the same ankle, like they were mocking me. I live in Chengdu, near a small park with decent greenery—and decent mosquitoes. From mid-April onward, the balcony becomes uninhabitable after dark. I’ve tried 8 different mosquito repellent methods over the past couple weeks. Here’s what happened. Completely useless: Mosquito repellent wristbands. Bought two—one for myself, one for the cat. Wore both for a week. Still got bitten. Mosquito repellent apps. Phone emits ultrasonic waves meant to repel mosquitoes. I ran an actual experiment: sat on the balcony with the app on, got two bites. Sat in the exact same spot with it off, still two bites. Pure placebo effect. Actually effective: First: DEET-based repellent spray. About 30% DEET concentration, applied to ankles and arms, lasts roughly 6 hours. Second: mosquito net. Physical barrier, most primitive but most reliable. Third: electric liquid mosquito repellent. Plug-in device with controlled heating, evenly vaporizing the repellent chemical. Works better than traditional coils, no smoke.
