Query: These have always worked for me

This is the best product I've found for controlling pantry moths. If the product doesn't work for you, try purchasing a product that uses a different type of lure (these use pheromone lures). The 2-pack is perfect for me. I put one trap in the pantry and one in the open somewhere in the kitchen. Note: For maximum effectiveness, use both traps at the same time. This is because the lures are packaged together and become activated when exposed to the air.
