Compared to bed bugs, bat bugs have longer fringe hairs that are placed under the head. Further, bat bugs are primarily found on attics and feed on the bat’s blood.

Cockroach nymphs physically look white when they hatch and molt but will become reddish-brown – just like bed bugs. They love moist, warm areas with food, including crevices and cracks. 

On the shape, cockroach nymphs are cylindrical and longer before molting (skeletal shedding), while bed bugs look like an apple seed or are oval-shaped and short in length. 

Cockroach nymphs will mainly be active at night time while bed bugs are active all the time. Further, you may get asthma if you get near cockroach nymphs, while bed bugs will lead to anemia. 

Cockroach nymphs will molt into adults to mature adults, but they’re wingless and sexually inactive before this. For example, the Oriental roach nymph may require about two years to molt into adults. 

Further, nutrition and environmental factors – besides species – may influence how fast the roach nymphs will molt into adults (maybe within months or years). 

After molting into adults, the roaches will retreat to a cool and dark place to allow their outer shell to thicken and dry. Controlling these bugs requires you to target the roach eggs – use boric acid or roach killers

Ensure the environment is clean and dry – avoid poorly disposing of any food waste as they may attach to the cockroach nymphs.  Further, seal off all holes and cracks the bugs may use to get into your house.
