Insect Bait and Lure Types

Forestry Distributing supplies many kinds of insect baits and lures, each designed to release a pheromone or other message-bearing chemical at a desired rate. Each type of lure is tested in the field against specific insects. To purchase a specific bait or lure, please explore our online inventory and contact us today.


Rubber Septa

• Used primarily for volatile moth pheromones, which are attractive to adult males.

• Used mainly for detection and monitoring of moth pests, such as codling moth and spruce budworm.

• Can be placed on the sticky surface of delta or other traps, but pheromone dispersion can be improved if hung from the roof of traps using a plastic tab.



• Made by adding a volatile semiochemical to a liquid plastic, which then hardens.

• Release rate determined by cutting lure to desired length.

• Semiochemical releases from walls and end of lure.

• Used for many types of pheromones, including nun moth sex pheromone, lineatin (an ambrosia beetle aggregation pheromone), and honey bee queen mandibular gland pheromone.



• Used to release large amounts of semiochemicals.

• Provide constant release rate until the material is gone.

• Typically used to release large amounts of host-plant volatiles like ethanol and alpha-pinene.

• High- and low-release ethanol sleeves available.

• Wide sleeves should be suspended on the outside of Lindgren or panel traps.


Bubble Caps

• Contain liquid lure in a reservoir with an impervious backing and a thin plastic membrane heat-sealed over the bubble.

• Used for release of pheromones at the milligram level at a constant rate over many weeks.

• Often used for bark beetle pheromones.

• Typically suspended within central column of Lindgren trap.


Polyethylene Bottles

• Used to provide intermediate release rates (between sleeves and bubble caps).

• Used to release small amounts of tree volatiles like alpha-pinene or myrcene.

• Used in Lindgren and panel traps. If used in Lindgren trap, should be placed to rest within the open central column.


Eppendorf Tubes

• Provide slightly lower release rates than polyethylene bottles.
