Another good biological pest control method is the use of pheromone traps.
A pheromone trap is a type of insect trap that uses pheromones to lure insects.
However, it is impractical in most cases to completely remove or "trap out" pests using a pheromone trap.
The way to detect pests and determine the optimum timing for sprays is through the use of pheromone traps.
Some moths, notably Sesiidae are monitored or collected using pheromone traps.
Sticky pheromone traps don't control them completely, but they can capture enough males to make breeding less successful.
Research performed by many US extension service branches has shown pheromone traps attract more beetles than they catch.
These traps are generally known as pheromone traps.
As an alternative, MacNeil suggests using the same pheromone traps to create a "Thrilla in Manila" by drawing the two creatures together.
