Centipede

6402  I’m wanting to know what the prominent bugs are on the glue strip that was left under the couch. I think they are the culprits that bite us and leave giant welts. I also have a photo a what appears to be the same bug, only 10 times bigger. thanks, Rod. Sycamore Ridge Drive, Simpsonville, SC 29681 United States

 

Number 6402. The largest critter at upper right is a centipede, possibly a house centipede (Scutigera coleoptrata). These are venomous, but will not bite unprovoked. Most of the insects on the strip appear to be flying ants or gnats; certainly nothing that would be responsible for any bites.

Duff millipedes

6337 These are tiny (approx 1-5mm) black worm-like but crawl like caterpillars. They’re inside my walls and climb up windows and walls and are spreading through the whole house wherever hasn’t been sprayed. I think they’re carpet beetle larvae but they’re not in my carpets. I’ve killed over 200 myself and pest control has been 3 times, I was told 99% of carpet beetle larvae don’t behave like this. This has been going on for 4 weeks and I am going crazy. Please help confirm what these are, they look like your recently posted photo but somewhat different. Thank you. From Victoria, BC.

Number 6337 These are duff millipedes (Diplopoda: Polyxenidae; Polyxenus sp.), sometimes also called dwarf or bristly millipedes. Normally found outdoors where they feed primarily on lichens and algae, they cause no harm and do not need control. Visit Click here for more detailed information.
