An insect trap works by using various methods to attract, capture, or kill insects. Common mechanisms include:
-
Attraction: Traps may use pheromones, light, color, or bait (like food or decaying organic matter) to lure insects into the trap.
-
Capture: Once attracted, insects may be caught in sticky surfaces, drowning in liquids, or contained by barriers that prevent escape.
-
Killing: Some traps incorporate insecticides or electrical grids to eliminate insects upon contact.
Overall, the effectiveness of an insect trap hinges on its ability to attract and retain the target insects.
