A bed bug infestation may begin in a single room, but you should keep in mind that they do not bite everyone in the house. Bed bugs are attracted to the warmth of human bodies and the carbon dioxide in their exhaled air. Once they find a host, they will feed for three to twelve minutes. They will not continue feeding if they feel threatened or disturbed. A bed bug infestation can take several months before the entire home is affected, so it is best to be cautious.
The reason why some people experience bed bug bites only when one person is present is because they are allergic to bed bugs. However, some people are not allergic to bed bugs, so they may not develop any signs of allergic reactions. In these cases, it is important to check other areas of the house to rule out bed bugs. This way, you can get rid of the infestation faster. Once you know whether there are bed bugs in a home, you can treat it appropriately.
Bed bug bites are usually small and not painful, but they may cause a lot of discomfort for the person infected. Some people might experience a slight itch, while others may develop painful, swollen bites. In severe cases, bedbug bites may even lead to a skin infection and blisters.
