I didn't need to try it because I found a better solution. For a very long time, I suffered from mosquitoes or other insects in my bedroom that bothered me immensely and wouldn't let me sleep. All night they would hover around my face. I used a device with evaporating liquid that I bought from the supermarket and that was it. From the very first night, no mosquito bothered me. At some point, I stopped turning on the anti-mosquito device but still zero mosquitoes. They probably had made a nest or something like that in my bedroom and the device either killed them or forced them to... move out.
