Nymphs of the elm seed bug
7243. Hi, just purchased a house in Vernon BC and noticing these bugs everywhere outside our sunroom door and even in the sunroom. They’re tiny, like 3 cm or less. The babies seem to have a rounder body and reddish bottom. TIA. Vernon, British Columbia. Canada
Number 7243. These could be nymphs of the elm seed bug (Arocatus melanocephalus; Hemiptera/Heteroptera: Lygaeidae), a recently introduced species which has become quite a nuisance pest. Elm Seed Bug Detailed Information
Yes! They are elm seed bugs. We ended up calling an exterminator company. They used a non-toxic spray for around the windows and doors as well told us to keep all wood and debris cleaned up around the yard (the adults overwinter in wood/bark), as well clean the seeds from the elm trees when they fall (which hadn’t been done in years!).
