Body divided into 3 distinct segments viz. head, thorax and abdomen
Air taken in through spiracles [small holes along body] and circulated through tracheoles to the body organs
All have 3 pairs of legs and many have 1 or 2 pairs of wings and

Fast breeding [ insect populations can increase 60 - 1000 x in a month]
Adaptable to changing environments and can survive adverse conditions
Cosmopolitan food consumption [ e.g. Tobacco moths eat spices, pasta, petfood, cereals and dried fruit as well]

Sexual attractant for male insects only. Pheromones naturally produces by the female. Often very specific i.e. red flour beetle
pheromone will not attract moth species. Act as a monitor – not a control measure Only trap some males – not all Should be replaced 4-6 weekly Do not place where they attract insects in
from outside e.g. by open doors Attract within a small range ~ 10 metres
