Let them know you are using the latest technology to minimize pesticide use. A visual attractant trap often resembles a food source or an egg laying or resting site used by the insect pest in nature. An example of this is a trap that looks like a large, ripe red apple that fools apple maggot flies into thinking they have found a prime egg laying site. Instead, they are stuck fast to the nondrying sticky adhesive on the surface. Another example is the yellow sticky trap, which resembles healthy plant foliage, a common feeding site for many insects.
Many female insects release an odor to signal their readiness for mating.
These odors, or pheromones, can be reproduced in a laboratory. This material is then applied to a rubber cap or other device and releases slowly over a period of several weeks when used in a trap. Trap and lure recommendations often vary by region. Check with your local Extension agent. When determining your costs, be sure to also figure in the cost of your time.
