Duff millipede

7269.       Hello, I live in Kelowna BC, it is currently the end of July 2021, and I have been stressing out over these bugs for at least a month now. They seemed to show up in large quantities out of nowhere and no amount of vacuuming and cleaning helps, they just come right back. Majority is always found around windows on the 1st (ground) floor. They congregate around AC vents, and can sit on the ceiling or walls for hours without moving. I’ve searched your website far and wide, and discovered a pest called duff millipede. Is this it? Kelowna, BC. Canada

 

Number 7269. This does appear to be a duff millipede. Although they often come indoors, they do no harm there.  duff millipede detailed information.
