Flour Insect Trap

TNAU Pit Fall Trap is modified to suit trapping of insects in wheat Flour / Maida / Spices Powder.

The top lid with 2mm perforation is fitted to a cylindrical tumbler shaped unit with a sieve of 0.8 – 0.9mm size at the bottom of tumbler.


The insects enter through the 2mm perforation in the top of tumbler portion and get settled over the 0.8 – 0.9mm sieve at the bottom.

Any spill over flour into the trap can get sieved out by gentle shaking of the trap unit or removed and thrown out as only a very very small quantity of flour will be inside and sometimes it may be with the eggs laid by the trapped insect.
