The eco-CLM trap consists of a rubber plug impregnated with a pheromone and a sticky paper trap. Simply open the trap, throw the plug inside (it will stick) and hang in your tree. For small trees use one trap. 
 
Female citrus leafminers only lay eggs on flushes of new growth so hang the trap when new growth commences.
 
Replace every 2 - 3 moths or sooner if the sticky trap is full,
