McPhail trap is a plastic trap of two interlocking sections -an inverted yellow funnel base with a small entrance at the bottom for insects, with a transparent, clear upper cap and a basket or cage to hold the pheromone dispenser. This is very effective for all kinds of fruit flies which enter into the trap thru the bottom entrance, are held in the funnel base due to light falling from the transparent upper cap and get killed due to lack of food & exhaustion.
