Sticky traps are apssive and anything that flies into them will get stuck. The prinmary use of sticky traps is to monitor what is in the garden. Yellow is supposed to be a color attractive to spotted cucumber beetles, but whether they will fly to and get stuck on any of these traps depends on a number of things.

I never, ever use them outside in the gardens. In cold climates, they can be used in greenhouses unless beneficials have been released. I stopped using them in my plastic houses (in the South) because the little green anoles kept getting stuck.

Many Integrated Pest Management people suggest using sticky traps, outside, as monitors to see what insects are flying around your garden, orchard, etc.
As long as people understand the sticky traps are a passive insect control measure and that they can also trap beneficials and they are willing to live with that, there is no reason to not use them outside.

yep that's what happens a non specific bug controller, we had a bug trap for mossies that uses oil in a tray works wll but on inspection caught every other non annoying bug but mossies.

used to use those blue light zappers same thing killed heaps of mossies very few flies but lots of other insects as well. we used sticky boards for tropical fruit fly again every other bug but the TFF. we net our susseptable fruits now old mossy nets or similar curtain material works well.

I thought you were supposed to use a scent lure on the sticky traps. Johnny's sells the traps and the lure. I can see not using the lure if you're looking to monitor what's going on. Is the lure affected by temp? Could that be the problem because your traps probably came with a lure?

no lure came with ours and no lure was ever mentioned. the traps were of paticular colours, ours was yellow and the colour was supposed to be the atractant, which it was or a good many bugs.

I got the trap from Garden's Alive; it was called sure-catch cucumber beetle trap and came with a lure.

Thanks for all your advice. I'm headed out to take it down.
