bed bugs

bed bug can individually and collectively cause a number of health effects including skin rashes, psychological effects and allergic symptoms. Bed bug bites or cimicosis may lead to a range of skin manifestations from no visible effects to prominent blisters. The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, 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. prominent wheals and bullae formation along with intense itching that may last several days. A central hemorrhagic spot may also occur due to the release of anticoagulants in the saliva.
Symptoms may not appear until some days after the bites have occurred

Other possible conditions with which these conditions can be confused include: scabies, allergic reactions, mosquito bites, spider bites, chicken pox and bacterial skin infections. the person from being repeatedly bitten and possible symptomatic use of antihistamines and corticosteroids (either topically or systemically). There however is no evidence that medications improve outcomes and symptoms usually resolving without treatment in 1–2 weeks.
Avoiding repeated bites can be difficult, since it usually requires eradicating bed bugs from a home or workplace; eradication frequently requires a combination of pesticide and non pesticide approaches. Pesticides that have historically been found to be effective include: pyrethroids, dichlorvos and malathion.
