Hi Florence, I'm no expert with pheromone traps but I can speak to them some because we implemented them last year. To your question if the pheromones attract other species: I think this is possible. I've noticed that silverfish in particular seem to be attracted to bait for dermestids. Based on our records, I don't believe it's possible for any insect to be discouraged by the presence of pheromones. For instance, this time last year we had about the same number of silverfish logged in one particular area as we did the year before, when we were not using pheromone traps. The presence of the pheromones did not have a repellent effect on this non-target species and the numbers remained consistent.
Not sure where you're purchasing your traps but perhaps the experts at https://www.insectslimited.com would have more insight to your particular concerns? Best of luck! -Josie ________________________________ From: 'Florence Fleury - Artena Heritage Preservation GmbH' via MuseumPests <[email protected]> Sent: Wednesday, June 25, 2025 1:12 PM To: [email protected] <[email protected]> Subject: [PestList] pheromone traps Hello, I have a question regarding pheromone traps: These are designed to attract a specific insect species (for example, clothes moths or carpet beetles). But is it possible for a pheromone trap targeting one species to also attract other insect species — or, on the contrary, to have a repellent effect on them? In other words, could a pheromone trap specifically designed for one species distort monitoring results by discouraging or failing to attract other insects that are actually present in a collection ? This would mean that targeted trapping doesn't necessarily provide a representative overview of the actual insect biodiversity in a space. Thank you in advance for any insights you can provide!
