How to test if it is mosquito repellent

My group in reserach are currently doing a study about using candles as a mosquito repellent. My question is, how can we know if our study works. Do we have to go to a testing center? If this the the choice, can you please suggest some huhu. Or do we have to try it by ourselves?
