I live in Oregon and lately, within the last few months, the bed
rooms of my house have been plagued with black beetle-like insects and
what looks like caterpillars that are both found on the beds but
(thankfully) nowhere else in the house. Does anybody know what these
pests are?
Where they come from?-- they just seem to materialize on the beds. And
a way to get rid of these nasty pests?
