Moth traps can only establish that you are infested by pantry moths or clothes moths.
Attention: moth traps lure in only a few males, never any females only attract male moths.
Many female moths are most certainly impregnated and therefore continue to lay their eggs. A single female lays up to 300 eggs, distributed one by one over a period of a week to 10 days.Pheromone traps have a very specific effect: one kind only works for food moths, the other clothes moths. By using the trap you can establish which pest you are dealing with.
When buying moth traps please let us know against which kind of moths you will use the traps: pantry moths or clothes moths.
