How to make?
- Make 10 to 12 holes into an old 1 liter plastic bottle or 3 holes on each side of 1 liter ice cream container, to allow moths to enter.
- Heat a small piece of metal to make the holes easily.
- Put a wire from the cover to suspend the bait.
- Secure the pheromone dispenser align with the entrance holes inside the trap.
- Make a rectangular opening into the lower part of the container for removing the moths caught.
How to use?
- Half-fill the trap with soapy water.
- Put bait in the pheromone dispenser or suspend the pheromone capsule from the lid using string or wire.
- Close the container.
the trap to a bamboo or wooden stake or hang on branch of a tree.
- Place traps for different pests at least 3 meters apart. If traps are used for monitoring the pests, 2-3 traps are enough for 1 ha field.

Reminders while using pheromone traps
- Buy the pheromone that lures the pest you want to control.
- Always label the trap. The name of the species you are trapping, the date the bait was placed, and the name of the bait if you are using several.
- Change bait according to manufacturer's recommendation.
- Dispose properly the bait wrappers. The tiny amount of pheromone left near the traps will compete with your bait.
- Wash your hands between handling baits. Minute traces of other chemicals can render the baits completely ineffective.
- Always remove all captured adults during each visit. Discard them away from the field. Put live ones into a bucket with soap solution to drown.
