Wasp invasion

Wasps started invading my apartment this week. They are getting in through my balcony somehow. And it is closed. Between the cat and myself we must have killed at least 50 in the past few days. I've never been stung and I don't want the cat getting stung.

So I started researching DIY wasp traps. And using some tips from WikiHow and and  an old 2 liter I made this:

As you can see, Sophie didn't want to be left out of the action. Especially when one of my tools was some leftover Peaches and Cream yarn. The trap is now on my balcony. I'm hoping this works. If it does I'll make 1-2 more.
