Mis-using pesticides (including "off-label" use) can & has injured or killed reptile pets...so please refrain from making a comment like this, or at least be very specific as to what & how it was used- otherwise readers may assume that any & all "bed bug spray" can be used this way with no harmful effects. Okay?
Just because something effectively kills bed bugs (or other pests) doesn't make it safe to use for pets of any kind, much less our sensitive & defenseless reptiles. Long term residual exposure can also do damage, even if nothing is obvious for a while (& that's true even of products designed for snake mites). I also suspect that not all "bed bug sprays" are created equal (ie. they don't all contain the same things).
