Re: the lowest power laser can kill the Mosquito
Swatter beats laser any time. Electric swatter beats anything. Well .. it has little effect on hornets, sadly, but it owns mosquitoes. Especially because it's easy to kill them in flight with it.
Laser has many problems. For example it is rather bright. If the mosquito sits on white wall, any laser able to kill the bloodsucker would dazzle you, and if you use protection goggles (as you actually should), you would have troubles spotting the poor bastard. If it sits on furniture, any laser able to kill it will damage the furniture. I mean yes, I too tried it .. but its just not practical.
Other insects I simply catch and release outside.
As for hornets .. sometimes they swoop into my room in the middle of night ! I just sit at the computer, killing zombies or something .. and boom, in a moment 5cm hornet is sitting on the screen.
I don't have the nerve to catch THAT alive ! And electric swatter just makes them laugh. I bought freezing insecticide in spray can after my last 'encounter' .. but haven't had the opportunity to test it yet. Not that I miss it ..
