I’ve cleaned the entire area…this time sprayed it all down with a bedbug killing spray (Raid). Everything, nooks, crannies, corners, the vent. I’ve also re-inspected my spare mattress. No sign of anything. I’ve gone as far as going into both. the inside of my boxspring has been saturated with the raid spray as is the “down” side of the mattress. I slashed into the side of the mattress and sprayed inside there too. I am going to be mopping with bleach in the morning and afterward I will do my spray down again.
Bedbugs are obligate blood parasites that belong to the insect family Cimicidae. Cimex lectularius and Cimex hemipterus, the two bedbug species that feed primarily on humans, are oval, reddish-brown, flat, and wingless. Adults are typically 4 to 7 mm in length (Figure 1). Nymphs can be as small as 1 mm, and are translucent and lighter in color 5,7 (Figure 2). Adult females produce 200 to 500 eggs in a typical six- to 12-month life span.5,8 Bedbugs can withstand temperatures from 44.6°F to 113°F (7°C to 45°C).8
To prevent bringing bed bugs to one's own home, travelers are advised to take precautions after visiting an infested site: generally, these include checking shoes on leaving the site, changing clothes in a garage before returning to their home, and putting the used clothes in a clothes dryer outside the house. When visiting a new lodging, it is advised to check the bed before taking suitcases into the sleeping area and putting the suitcase on a raised stand to make bedbugs less able to crawl in. "An extreme measure would be putting the suitcase in the tub." Clothes should be hung up or left in the suitcase, and never left on the floor.  The founder of a company dedicated to bedbug extermination said that 5% of hotel rooms he books into were infested. He advised people never to sit down on public transport; check office chairs, plane seats and hotel mattresses, and monitor and vacuum home beds once a month.
Another clue to infestation is odor. Like many species of bugs, bed bugs release odors called alarm pheromones. When a group of bed bugs gets disturbed, you may get a whiff of that odor, which is similar to the odor stink bugs give off. At higher concentrations the odor is unpleasant. Some people say at low concentrations it's a pleasant smell—like coriander. In fact, older literature refers to the bed bug as the coriander bug. I've tried to smell the coriander scent in bed bug alarm pheromones and have not been able to make the connection, however.
Hey Jessica! Sounds like bed bug bites to me but don’t stress, although bed bugs are known to travel with you from other locations its not a guarantee that they always do. I recommend giving all your clothing a hot wash when you get back home (and your travel bags) and to inspect your bed for signs of their presence. As a precautionary measure, you can put DE under your sheets for a day or two and that will kill any pests that are hiding there. Good luck
To reduce the effects of swelling and rashes, you could take an over-the-counter antihistamine, which is usually in the form of an oral pill. Be sure to check the product label for possible side effects, though: some may cause drowsiness, dizziness, irritability, and vision changes, ringing in the ears, and other disrupting symptoms. You’ll want to be careful about taking these pills if you’re going to be driving or operating heavy machinery, and you definitely want to talk to your doctor first if you’re pregnant or have high blood pressure.
This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area). The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.
Found worldwide, bedbugs are most common in developing countries. Still, reports of bedbugs in luxury hotels are not uncommon. They are most commonly found in areas like hostels, hotels, shelters, and apartment complexes where there are many visitors coming and going. When they enter your home, it's often because they have hidden in luggage, furniture, clothing, or boxes that are being moved. They can also travel on pets' fur. Increases in international travel may be responsible for the rise in bedbug sightings.
The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, increased immigration from the developing world to the developed world, more frequent exchange of second-hand furnishings among homes, a greater focus on control of other pests, resulting in neglect of bed bug countermeasures, and increasing resistance to pesticides. Declines in household cockroach populations that have resulted from the use of insecticides effective against this major bed bug predator have aided the bed bugs' resurgence, as have bans on DDT and other potent pesticides.[medical citation needed]
Bed bugs are active mainly at night. During the daytime, they prefer to hide close to where people sleep. Their flattened bodies enable them to fit into tiny crevices--especially those associated with mattresses, box springs, bed frames and headboards. Bed bugs do not have nests like ants or bees, but do tend to congregate in habitual hiding places. Characteristically, these areas are marked by dark spotting and staining, which is the dried excrement of the bugs. Also present will be hatched and un-hatched eggs, the tannish shed skins of maturing nymphs, and the bugs themselves. Another possible sign are rusty or reddish smears on bed sheets or mattresses from crushed engorged bed bugs. Although it’s often stated that bed bugs have a telltale “buggy” odor, the smell is seldom evident except in extreme infestations and should not be relied upon for detection.
Zonalon and Prudoxin (doxepin) are topical creams that can be prescribed for relief from itching. The active ingredient in these products is a topical tricyclic antidepressant and seems to work against itching by reducing histamine. Histamines are chemicals your body produces in response to injury or when having an allergic reaction. A prescription-strength cortisone cream may also help. In some cases, a prescription antihistamine will be given.
Medicated shampoos–both over-the-counter and prescription–can help get rid of them, as can combing and re-combing your hair carefully and disposing of the critters. If you do get head lice, don’t share anything that goes on your head (including hats, brushes, headphones, or hair accessories), and make sure you clean bedding and clothing that could have been infested in hot water.
Some firms want beds stripped and furniture moved before they arrive, while other firms prefer to inspect first and perform these tasks themselves. Clutter and belongings on floors (especially beneath beds) must be removed since they impede treatment and afford additional places for bugs to hide. Bedding and garments normally will need to be laundered and/or hot dried (120°F minimum) since they cannot be treated with insecticides. An effective and efficient alternative to laundering is to simply place bedding, clothing, toys, shoes, backpacks, etc., in a clothes dryer set at medium-to-high heat for 10 to 20 minutes. This can be done in lieu of washing and will kill all bed bug life stages.
Chances are, you or someone you know has had a run-in with bed bugs. It might have happened in a scrupulously clean bedroom. Or maybe it was a hotel room, office or college dorm. In the February issue of Scientific American entomologist Kenneth Haynes of the University of Kentucky explains how, after a lengthy absence, bed bugs are staging a comeback. The good news is scientists are intensively studying these insects, and their insights suggest novel ways of detecting the bugs and eradicating infestations. Some of those potential solutions are a long way off, however. In the meantime the best bet is to avoid bringing bed bugs home in the first place. I called Haynes to ask him how to do that and what to do if one suspects an infestation (eek!), among a bunch of other practical-minded questions.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
