Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed. Dark spots (about this size: •), which are bed bug excrement and may bleed on the fabric like a marker would. Eggs and eggshells, which are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger.
They are visible to the naked eye. Adult bed bugs are usually brown in colour. When filled with blood, their colour ranges from red to dark brown. They are oval in shape and about the size of a flattened apple seed, 4 to 7 mm in length.
Adult bedbugs are indeed visible to the human eye — although some of us may need to put on our prescription glasses. Bedbugs are usually about the size of an apple seed, which is about 5 to 7 millimeters long, according to the Environmental Protection Agency.
Check Common Bed Bug Hiding Spots
Using a flashlight and a stiff, flat-edged object like a credit card or paint scraper, check around beds, mattresses, and other areas where you suspect you might have bed bugs. Look for actual bugs, eggs, feces, or molted skin as evidence of an infestation.
Signs of Infestation
Blood stains on your sheets or pillowcases. Dark or rusty spots of bedbug excrement on sheets and mattresses, bed clothes, and walls. Bedbug fecal spots, egg shells, or shed skins in areas where bedbugs hide. An offensive, musty odor from the bugs' scent glands.
Bed bugs live throughout the year, but there is a particular time during each year when bed bug infestations become more common. In normal years, bed bug “season” peaks in the months of August and September when most families have returned from their travels, and bugs have a chance to gain a foothold.
Of all the signs related to a bed bug infestation, bites are probably the most obvious (and most common). Bed bug bites can be flat or raised, and are characterized by itchy, red spots that tend to show up in a zigzag or cluster. They'll often appear on the chest, back, neck, feet, face, and hands.
They can come from other infested areas or from used furniture. They can hitch a ride in luggage, purses, backpacks, or other items placed on soft or upholstered surfaces. They can travel between rooms in multi-unit buildings, such as apartment complexes and hotels.
Adult bed bugs have a flat oval-shaped body, which is light brown in colour and may become red and engorged after a blood meal. Ranging in length from 1 - 5mm, fully-grown adults reach a similar size to an apple seed. They have six legs, long antennae and large mandibles (mouth parts), which can impale human skin.
Bed bugs are shifty pests that typically like to hide no further than a few feet away from their hosts. Therefore, cracks in bed frames, headboards, box springs, mattress seams and even your dresser are all places bed bugs will reside during the day.
small red bumps or welts in a zigzag pattern or a line. small red bumps surrounded by blisters or hives. papular eruptions or areas of skin with raised or flat patches that may be inflamed. small spots of blood from bites often dried or stained onto sheets or bed clothing.
Bed Bug Feeding
The bugs can bite several times in a night to become full but only feed about once every one or two weeks. People that have only small numbers of the bugs in their homes may not experience new bites every night.
When bed bugs infest, they will leave blood stains on sheets, pillowcases, blankets, mattresses, box springs, furniture, carpets, molding, and more. These stains may be red but, most of the time, they appear tan or brown. Significant staining is associated with areas of infestation.
There are many smells that bed bugs don't like. If you're spraying your luggage, clothing, or bedding, use a scent that you like. Lavender, peppermint, or lemon can do the trick. There are many essential oils to choose from.
Pyrethroids are synthetic chemical insecticides that act like pyrethrins. Both compounds are lethal to bed bugs and can flush bed bugs out of their hiding places and kill them.
Mattresses and pillows make potential habitats for bed bugs. Pillows may also be host to bed bug eggs, making them a potential point of bed bug infestations. A possible sign that bed bugs have infested pillows may be the appearance of bites.
One out of five Americans has had a bed bug infestation in their home or knows someone who has encountered bed bugs at home or in a hotel.
Don't count on bed bugs to go away on their own. In theory, they can. In practice, they don't unless several highly specific circumstances occur. Your best bet is professional bed bugs treatment.
Most people do not realize they have been bitten until bite marks appear anywhere from one to several days after the initial bite. The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line.
Wash bedding and clothes in hot water for 30 minutes. Then put them in a dryer on the highest heat setting for 30 minutes. Use a steamer on mattresses, couches, and other places where bedbugs hide. Pack up infested items in black bags and leave them outside on a hot day that reaches 95°F (35°C) or in a closed car.
Do Bed Bugs Usually Stay In One Room? Since bed bugs do not have wings and do not jump, some people incorrectly assume that they tend to stay in one room and not travel much. However, this is not true. Bed bugs move around quickly and seek any place where they can find their next blood meal (i.e. humans).
Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep - the hands, neck, face, shoulders, legs and arms. While not always the case, bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern.
