Outdoor trapping, making it work for you

Outdoor trapping, making it work for you

Outdoor trapping can be one of the most important, and most overlooked elements of your pheromone program. Read on to learn why it is important as well as some common misconceptions, and how to set up a program.

Knowing the pest pressure coming from outdoors can explain interior trap catches that don’t seem to relate to an infestation indoors..  Several types of common food pests can exist in large numbers in the wild and may just be waiting to come inside. The most common source for some of these insects in residential areas may be from nearby trees that have dropped acorns, walnuts, hickory nuts etc, in the autumn months. Another common source is bird seed in a neighbor’s garage that becomes infested. In industrial settings, infestations can come from nearby food manufacturing facilities, spilled grain on rail tracks, spillage from grain bins, or from grain that has fallen on the ground in agriculture fields.

It is common and perfectly reasonable question to ask “If I’m putting pheromone traps near my facility, aren’t I attracting insects to come in?!” The short answer is “no.” Pheromone traps attract only males who are incapable of infesting product. Also, if you are catching insects in your traps you know that the insects are ALREADY THERE If you know you are catching males in your pheromone traps, females are present as well but are not drawn to the trap. The information you are gaining from your outdoor trapping program can be used to enhance your pest program as well as reduce infestations

Warm months are the best time to monitor your outside insect pressure. The most common food insects found outdoors are warehouse beetle, Indian meal moth, and cigarette beetle. Your goal is to create an outdoor perimeter by placing traps 30-50’ away from the building being monitored. Place the traps approximately 50’ apart if possible, larger facilities may require 75-100’. Tie off the traps on existing fences, trees or onto stakes placed into the ground. Doorways and outdoor loading docks are one of your biggest sources of infiltration meaning that these areas should have a greater concentration of outdoor monitors. Aim for 20-30’ spacing in these high-risk areas.
