Sales barrow makeover

Sales are slow but then there aren't many holiday makers looking to take home a few veg plants   . I've had to remove the bird boxes that bob made, from the Barrow.  Mrs. Wasp decided a nest box was a perfect place for her to raise her offspring.  Mrs. Wasp's nest was relocated as best I could , while she was out. Hopefully she'll think the money box to small to build in.

Could you put a cork/plug or some sort in the hole? Maybe just a "Buzz off" sign would warn Mrs Wasp off?

We did consider putting tape over the holes with a note explaining. We might do that yet. I like the buzz off idea    .
We’ve managed to sell a couple of them. While they were still on show   .
