The answer to 'how did bed bugs get in my house' is that bed bugs can be brought into a home in a variety of ways, such as through infested furniture, luggage, clothing, or even on a person's body. Bed bugs are small, brownish insects that feed on human blood and can be difficult to detect, especially in the early stages of an infestation.
Bed bugs are excellent hitchhikers and can be easily transported from place to place, such as hotels, apartments, or even movie theaters. They can also spread between neighboring units in multi-unit buildings. Once they've been introduced into a home, bed bugs can quickly multiply and establish a colony, leading to a full-blown infestation.
