Yes bedbugs are visible to the naked eye. Adult bedbugs are about 5 millimetres in length, and very flat looking and reddish brown in color. Bedbug nymps are smaller in size than the adults are, but are also visible to the naked eye. If you have bedbugs infesting a bed, you are very likely to see them if you turn or move your mattress around in the daytime, as they do not like daylight and if you disturb them they will move quite quickly to try to find somewhere dark again. They normally only come out when it is pitched dark to climb on to feed off the blood of a sleeping human for about 5 minutes most usually just before sunrise then return to their hiding place, which may be in the bed or nearby.
The most usual place you will find bedbugs in the day time hiding is in the folds or crevices of mattresses, but they may be anywhere in the bedding, or in cracks or crevices in the furniture or walls near to the bed. Unhatched bedbug eggs are more difficult to see, as they look like a grain of salt stuck to a hard surface, but they too are visible to people with normal eyesight. However some people get confused between bedbugs and dustmites. Dustmites are very much smaller than bedbugs and so are not visible to the naked eye. Almost all beds will have dustmites, but only a few people will have a bedbug problem in their bed which is much more unpleasant.
If you see critters in the bed, immediately change the bed linens! Spray the mattress with Nix or other spray for lice available at your pharmacy. Regular bug spray won't do the trick. Wet the mattress lightly with the spray, and allow the mattress to dry completely. Vacuum the bed and throw the vacuum bag away OUTSIDE. Wash the bed linens separately in hot water with bleach and detergent. Dry the linens thoroughly, absolutely hot dry. Sorry about the bed pillows, they need to be discarded.
This treatment works for most critters, visible and invisible. It is wise to carefully inspect the person sleeping in the bed for signs of bites or active critters.
