I captured a mosquito once and tried to bother it by slowly sweeping across the whole spectrum from a couple of Hz to ~300 kHz, using various speaker designs. The mosquito was unfazed.
The only repellents that actually work are chemical ones, but they're not efficient outdoors when it's windy, with the exception of the ones you apply directly on your skin.
