Lures

Lures can be changed every 4-6 weeks to get the most accurate results.

Lures handling

Pheromone lures are a very sensitive tool. They can be affected by exposure to elevated heat and direct sunshine. Direct touching by hand may cause cross contamination leading to mixed catches in the trap. Some contaminants such as Nicotine May have repellent effect reducing trap catch.

Lure Storage

Store in a cool dry place.

Shelf life can vary from 3-36 months depending on the storage temperature.
