The effect is better in uninhabited environment, because people’s body temperature and smell are more attractive to mosquitoes. This product uses the physical way to kill mosquitoes, it can't kill a mosquito when just turning it on. Do not open the bottom tray immediately in the morning because the mosquitoes trapped inside the tray may fly out. Keep it running for 2 more hours so that the mosquitoes suffocate to death.
