Wait until nighttime and turn the lights off. Use a flashlight with a red lens and scoop up the damsels while they are sleeping.
ps-if you don't have a red lens, get a red marker. Don't color the lens like you are coloring on paper, rather use a pecking motion to place dots on the lens. This way you get a thick coat of red marker on the lens instead of wiping off marker everytime you make a stroke.
