They are as follows: a trusty flashlight ( or torch for the uk readers) a handy clear mason jar with lid, and some rubbing alcohol.
Put a small amount of rubbing alcohol in the jar. An ounce will do it. It creates fumes that knock out the mosquito in about 30 seconds.
Flip on the light and locate the beast. Ruffle your closet to get them out into sight. They also love hanging out right above your bed. Don’t move too fast in on her.
Place the lip of the jar around the skeeter. She knows she is trapped. Let the fumes do their work.
Repeat until your room is free of the blood suckers.
Place the lid on the jar to save cost of rubbing alcohol and to remind you that you should check again tomorrow.
My advanced apologies to any Buddhists or PETA members. This is the circle of life in action.
