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.
Traditional methods of repelling and/or killing bed bugs include the use of plants, fungi, and insects (or their extracts), such as black pepper; black cohosh (Actaea racemosa); Pseudarthria hookeri; Laggera alata (Chinese yángmáo cǎo | 羊毛草); Eucalyptus saligna oil; henna (Lawsonia inermis or camphire); "infused oil of Melolontha vulgaris" (presumably cockchafer); fly agaric (Amanita muscaria); tobacco; "heated oil of Terebinthina" (i.e. true turpentine); wild mint (Mentha arvensis); narrow-leaved pepperwort (Lepidium ruderale); Myrica spp. (e.g. bayberry); Robert geranium (Geranium robertianum); bugbane (Cimicifuga spp.); "herb and seeds of Cannabis"; "opulus" berries (possibly maple or European cranberrybush); masked hunter bugs (Reduvius personatus), "and many others".
About five weeks ago bed bugs were found out work, then two weeks ago they spread, pest control has seen continuously coming to check and yesterday they gave the place the green light. I work with a largely indigent populace, the office I work at was not sprayed, during the night at some point, I will feel painful stings, hours later I have been finding small lumps or even large and hard ones, Could it be bed bugs? There is a particularly painful lump on the back of my thigh, it’s very hard too.
They will starve but not die off completely. That’s why you need to sweep, vacuum, and steam the floors daily. If bed bugs don’t feed on you then they can’t lay eggs. Eventually the numbers will diminish. They might even consider relocating. If you share an apt, it would speed up the process if your housemates do the same thing. It may take months to fully get rid of them but at least you won’t be their meal if you follow me bed proofing instructions.
