Also, they’re sensitive to moving shadows. As with motion sensors, if you move slowly enough, they cannot sense you. Slowly circle behind them and they jump into your death mitts.
Anyway, this has worked out better for me than a Bic lighter and hair spray. But that works too.
Any kind of spray you have lying around should make their wings too laden to fly. Simple Green, Windex, Axe Body Spray, etc. Could probably just be a spray bottle with water too.
Then you can do what you will with them.
