I found 2 box elder bugs in my grow room. is this a problem?
Although they specialize on Acer seeds, they may pierce plant tissues while feeding. They are not known to cause significant damage and are not considered to be agricultural pests. However, their congregation habits and excreta can annoy people; for this reason, they are considered nuisance pests. Removal of boxelder and other Acer species can help in control of bug populations.
So, no, nothing to be concern, however, get rid of them
