Yellow sticker against midges

Since our plants are irregularly watered by various wannabe gardeners, those little black mosquitoes have increased in recent weeks. Since we partly have customer traffic in the office is not recommended electric battle with the electric Schröter. On the electric Schröter we lost two good customers. (The customer stayed glued to the electric Schröter)

Now with the Yellow sticker our customers are retained, but the mosquitoes remain at the stickers stick.
