Query: The best way to use pest traps

Yes, the moth pheromone wafers are very effective at attracting moths. No, the traps are not very good at catching them. I have tried these, and many similar brands, all with the same problem. Here's what you do: Buy the pest trap. Take out the pheromone wafer and throw away the rest. Buy a fly paper ribbon (maybe fifty cents) and hang it up. Stick the two pheromone wafers on the fly ribbon, about a foot apart. This will catch meal moths for weeks, and will stay sticky even with dozens of moths on it.
