Yellow for bug traps?
My neighbor is collecting yellow plastic dishes and bottles to make insect pest traps for her garden in the spring. She saw on a gardening blog that insect pests, particularly squash bugs, are especially attracted to yellow.
Now I am skeptical, but on the other hand this same lady told me about making a fruit fly trap by putting a quarter-cup of apple cider vinegar with a few drops of dish-washing soap in a mason jar with a paper cone as a funnel in the top to encourage them in. That worked wonderfully, so I am not ready to dismiss her yellow plastic trap idea out of hand, especially if there is any hope of winning the fight with squash bugs.
Has anybody tried this, to know if yellow is any more effective than any other color for garden pest traps?
