The first step for a successful control of moths in the household is a so called „monitoring“, usually the catching of the moths with pheromone traps.
By means of specific acting sticky traps that bear the attractant of virgin female moths, it can be determined if and which moths are being active.
With a pheromone trap no female moths are caught and only a part of the existing male moths! Traps are a mere measure for monitoring moths. If male moths fly around, then the egg laying females are also around and Trichogramma parasitic wasps should be used for control.
The pheromones for the different kinds of food moths (Indian meal moth, Mediterranean flour moth, warehouse moth) differ from the ones for the moths that damage textiles (clothes moth, case-bearing clothes moth). If they stick on a trap for food moths, there is an infestation in the kitchen or in the storeroom, as food moths do not eat textiles and clothes moths in turn do not eat ceral products.
New kinds of pheromone traps, like our combined trap, catch both food moths and clothes moths, depending on occurrence. Moths can be distinguished by pictures on the trap.
Pheromone traps: easy to use and nontoxic!
The pheromone traps for the household are simply opened and positioned. They are immediately ready for use. Per room only one trap should be used so that the moths can orientate themselves to the scent. Too many traps have the opposite effect: they impede each other as the male moths loose orientation in the fragrance and do not find the sticky traps.
Places in which moths have already been observed are especially suitable as locations for traps.
While food moths also sit on open surfaces, clothes moths stay more in the wardrobe or near the ground (e.g. carpet). The traps should not be hidden from the moths and should not be positioned too hidden.
Control the traps and document the catches!
During the control or afterwards: it is always important to control the trap regularly and to document the catch. 1-2 times a week one should take a look at the trap and make a note of the number of new moths in the calendar or the enclosed recording sheet.
Combinable with the use of parasitic wasps
The pheromones last up to half a year, but should be replaced after approx. 3 months, in order to obtain a constantly good catching effect. The attractants for moths are completely nontoxic and are also of no interest for the Trichogramma parasitic wasps.
Pheromone traps bought ahead should be stored in a cool place, e.g. in the fridge or in the cellar, so that the attractant does not vanish prematurely.
