Bed Bugs Vs. Mites – How to Tell the Difference
1. Physical Appearance i. Size
Bed bugs: On size, bed bugs will grow to about 1/4 of an inch (1 – 6.8 mm) in length – adults measure 5 mm to 7 mm – an apple seed’s size in length.
Bed bugs are oval-shaped but flat, have six legs, and two antennae. Eggs are pin-head sized (1 mm) while nymph stage measure; 1st stage (1.5 mm), 2nd (2 mm), 3rd (2.5 mm), 4th (3 mm), and 5th (4.5 mm).
Mites: Mites have an unsegmented body, and the length of their body is 0.2 mm – many of these bugs measure under 1 mm. Velvet mites are 6 mm to 8 mm in length and are bright-colored with fine hairs.
Dust mites (0.2 mm to 0.3 mm) have no antennae or eyes and won’t sting, and are not parasites. These bugs aren’t visible with the naked human eyes – use a magnifying glass plus microscope.
Bed bugs: Before taking a blood-meal, adult bed bugs are rusty-brown and mahogany in color – colored reddish to tan. But after they’re engorged, they’ll be red-brown.

Their pear-shaped, rounded, and soft body is covered by pale hairs that’s fine. As noted above, mites (with their unsegmented body) are 0.04 inches.
Due to the tiny body size, mites species may be over-looked – some are parasites, predators, decomposers (living in soil) while are others exist in the water while the rest exist in plants.
2. Natural habitats
Bed bugs will mainly hide in tiny crevices and cracks around human sleeping and living areas. You’ll find them on furniture crevices, upholstery, wallpaper, and baseboards.

Spider mites feed on several plants like house plants & American-elm trees – their juice and soft tissues. Further, species like house dust mites will feed on dead tissue – they aren’t parasitic.
Also, dust mites will eat the dead skin cells that are shed by humans. Further, some mites are predators and will eat other mites. But most aren’t harmful.
