There’s a piezo electric mozzie zapper device which is the same thing as the click-starter on a bbq or gas hot water system. Gas stove’s have them too but they’re often mains powered. If you see an old gas hot water system on the nature strip you can extract the clicker/zapper without tools. Then you zap the mozzie bite to help with the itch. Or, and maybe TMI, zap your partners bits while blindfolded but consenting. It’s a pretty mild zap, as young teens we’d collect them to torment each other.
