As the weather warms, more of you have been eating your WFD on your patios. We have a lovely 2nd floor deck with a lovely view, and we rarely if ever dine on it anymore because it is a wasp/yellow jacket magnet. Funny thing, there is not foliage up there. But the metal rails holding our glass panes together have just a little opening in each “T” intersection that the pests love to fly into. For what reason escapes me entirely, since we’ve done tests and they are really no bigger openings than maybe 2x the size of a thimble.
We bought these yellow pear shaped wasp traps last year and had decent luck with them. This year, we are catching zero. I’ve googled wasp bait recipes, and am curious about your failsafes. And also, if you put up traps regularly, are there seasons/times when the same bait just doesn’t lure them, and do you have any idea why?
We’ve used this year (and I think last year too when it actually worked) - lemonade or apple juice both fortified with some extra sugar and a bit of vinegar (to keep the bees out). Also honey water. The traps have caught 3 wasps over a 3 wk period. Ish. I haven’t tried to put out tuna or anything, because I’m afraid it will start to get disgusting fast, and we’ll have to clean the traps more often than I’d like or realistically could get to.
