This is a photograph of moths that were looking for a good time.
The pink square contains synthetic moth sex hormone, the card is coated with super sticky glue. The moths fly in, get stuck in the glue, and there they stay.
This one is called BioCare, and is made by Springstar.net
I got mine in a big box store in the pest department. It contains nothing that can harm you, unless you happen to be a moth.
One caution: don't think that if one of these is good, four of them would be 4 times as good. Your home could become a moth sex-hormone beacon to every moth in the area who is to have a good time.
Ask me how I know...
