ATFE – Active Trap Field Entrance

Comparing different brands of Spider and Insect traps is complicated by the number of traps and claims of large active trap surfaces.
The key to an effective trap is the entrance an insect will use to enter the trap. The size of the trap beyond the entrance determines how MANY insects a trap can hold, but getting into the trap is all about the entry zone.
ATFE – Active Trap Field Entrance is the length in inches that a insect can enter the trap from either side.
Written as a # followed by ATFE (or sometimes ATFe) you can compare multiple brands based on the size of the entrance. For example a 13 ATFE is over TWICE as effective as a 6 ATFE trap.
