These are gathering all over my house – inside and outside. Just checked the guest room and they look like a wallpaper pattern on the wall – is this like the ladybug’s attraction my house – something about pheromones or something? Thanks – I’m a fly fisherman and have book marked your site.

Western Conifer Seed Bug

Hi Marc,
This is a Western Conifer Seed Bug,
Leptoglossus occidentalis.  Since the 1960s, they have greatly expanded their range from the Pacific Northwest to include much North America in the northern latitudes.  They have also spread to Europe.  Western Conifer Seed Bugs will enter homes to hibernate when the weather cools.

If I never expressed my thanks to you for helping the ID of those Western Conifer Seed bugs in my house, I do so now.
Much easier to handle a household pest once you know what they can and cannot do.

Thanks so much for writing back Marc.  We had a tough day and your kindness is much appreciated at this point.

  1. I live in Strafford County New Hampshire. We live on a river and are surrounded by pine trees. This year, much more then past years, we are experiencing a pest problem with the Western Conifer Seed Bug. What is effecting them this year particularly, AND what is that pungent smell they emit when you disturb them?
    Thanks ahead!

    • Insect populations move in cycles. This is just a year when the Western Conifer Seed Bugs are plentiful. Many Hemipterans, not only Stink Bugs, can emit odors.
