The trick is to pay attention to the spot where the bugs leave the bites as well as how the bites look. If the bites are near the place where your body meets the surface of your bed and they are in large clusters then you most likely have bedbugs.
In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says.
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.
Because bed bug bites affect everyone differently, some people may have no reaction and will not develop bite marks or any other visible signs of being bitten. Other people may be allergic to the bed bugs and can react adversely to the bites.
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.
If you've already gone inside your home, use a steamer to clean the carpets, drapes, linens, and mattress. Wrap your mattress in a bed bug proof cover. Place bedbug interceptors on the feet of your bed for a few nights just to be sure you killed everything.
Finding one bed bug in a home is not necessarily a sign that an infestation is present. If you found a single bed bug, killed it, and can't find another after a thorough search, wait for a few days. Bed bugs don't take time off; if there are more, they will show themselves. Be vigilant.
Remove sheets, pillows, and any clothing, towels, stuffed animals, or textiles that may have been exposed to bedbugs, and carefully seal them up in heavy-duty garbage bags. When you're ready, remove these items and loosely pack them in the dryer. Run it on the hottest cycle for 30 minutes to kill any bugs or eggs.
“The bed bug is a stressor like many other stressors,” Perron says. “For people who are vulnerable, it may result in having a pathological fear of bedbugs or even delusions of parasitosis,” when a person falsely believes they are infested with bugs.
Light Bed Bug Infestation
Minimal fecal staining (small black stains in areas of travel, feeding, and harborage). Fecal stains will be anywhere the bed bugs hide or travel and can be used to detect hot spots. Minimal cast skins (exuviae are the skins shed during the molting process).
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.
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.
Besides bedbugs, numerous insects bite at night. These night biters can be mites, fleas, mosquitoes, lice, spiders, and ticks. Most of these insect bite marks look alike; hence, you should first look for bedbugs and investigate further. These insects certainly don't bite you when you're in bed.
Hogan said that if you don't see any bugs and haven't traveled relatively recently, you may want to consider things like detergents, medications you may be taking, allergy issues, and more because one of those other things might be what's actually causing the itchiness.
Household products or environmental irritants could cause hives or rashes. If no pests can be found and the irritation doesn't seem to match any of the most common bug bite pictures, you may be experiencing a skin reaction to a household product or environmental irritant.
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.
Key messages. Bedbugs are a relatively common pest across Australia. Bedbugs can be difficult to remove because their eggs are difficult to see, have a significant incubation period and can quickly infest new sites.
Bed bugs have another defense system that prevents you from feeling you've been bitten. They inject an anesthetic (numbing) and an anticoagulant (stops bleeding) into your skin when they bite. You may not notice you've been bitten until the bite marks appear, which can take from one to a couple of days after the bites.
