The article is not actually describing bedbugs.
Bedbugs (Cimex lectularius)
Do not live in gardens
Are not green
Are not attracted to plants, humidity, or radiators
Are mainly spread through luggage, furniture, and bedding
Feed on human blood and hide in mattresses, bed frames, and cracks
Palomena is a green stink bug, not a bedbug
These insects do come indoors in fall
They are attracted to warmth
They do enter through cracks and windows
They are commonly repelled by strong scents (mint, lavender, vinegar)
So your article is actually about stink bugs, not bedbugs.
