About Ed Saugstad
Expertise
Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management.
If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.

21 years in the U.S. Army as a medical entomologist; duties varied from surveillance of pest populations (including mosquitoes, cockroaches, ticks, and stored products pests) to conducting research on mosquito-virus ecological relationships and mosquito faunal studies. Ten years as a civilian analyst for the Department of Defense, primarily on distribution of vector-borne diseases worldwide. Limited experience on surveillance of agricultural insects in North Dakota and Indiana.

Expert: Ed Saugstad - 11/7/2009
Question
Hi,
Recently there is plenty of dust like insect in my room, they usually hanging on the wall and ceiling. They move really slow as we did not notice any movement from it by monitoring it for 5 to 10 minutes. Please help to identify what is this insect and any method of get rid of it.
Many thanks....
Answer
Dear Ty - These most likely are nuisance pests known as household casebearers or plaster bagworms - see http://tinyurl.com/ykbhp9y for an image. These cases are constructed by larvae (caterpillars) of moths in the family Tiniedae, to which clothes moths belong. However, these caterpillars seem to prefer to feed on old cobwebs and the like, rather than munching down on your fine woolens. See http://tinyurl.com/yazjef7 for more detailed information; about the only control necessary would be to vacuum them up and dispose in the trash.
Hope this helps,
Saugy
