Bed bugs typically feed at night when we are sleeping. Even though these pests commonly feed for 5 minutes, the bite itself is painless and usually goes undetected at the time. In fact, bed bugs inject an anticoagulant (a blood thinner) as they feed, which makes feeding easier for the bed bug and also less detectable to you. Although you may not see the bed bugs, or feel their bites, they know when you are around. Bed bugs are attracted to warmth and carbon dioxide. So, if you are alive, warm, and breathing - then you are broadcasting loudly and clearly to all nearby bed bugs that "dinner is served!"
If you are experiencing itching, burning, and other forms of pain, there are a couple of treatment methods you could try. The most common recommendation is a topical corticosteroid cream or an anesthetic, which are applied directly to the wound and rubbed in to provide relief from the itching. A possible alternative to corticosteroids is calamine cream, though the FDA isn’t convinced of its effectiveness.
I know when you get infested with these, the bedding and mattresses all have to go. We are just barely scraping by as it is, and we have a bed for each kid no matter how often they come to see us – including ours, that’s SEVEN mattresses and bedding sets. Our landlord is not returning our calls, and although I know that he is responsible for not treating the problem which (per neighbor reports) the previous tenants had, too. But the lawyer wants $500 to even send a LETTER, let alone go to court. And I keep thinking that even if we go to court and win, the courts will make him treat the apartment…not replace the furniture that’s effected because of it. So…we sleep on floors, with newspapers?
No one tactic alone will be effective. A good pest control operator will develop a strategy to deal with the bed bugs that takes the particulars of the setting into account, and will return several times to check on progress. Dry ice sprays that freeze bed bugs have limited potential to reach hidden bugs. Steam has somewhat better penetrating ability. The downside of steam is that it leaves moisture behind. Dry ice doesn't leave any residue at all. Vacuuming has a role, but it has limitations, too. Some insecticides leave behind deposits that are slow to act but are effective in the long-term. Other insecticides kill on contact, but only reach insects that are in view. Insecticide resistance makes the choice of tactics more difficult.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
