<human>:  How can I detect bed bugs in my house?
<bot>: One way to detect bed bugs in your house is to thoroughly inspect your mattress, furniture, and other soft surfaces for telltale signs of bed bugs, such as small dark spots from their droppings or shed skins, a sweet musty odor, blood stains, or rust-colored spots. If you find any of these signs, you should contact your local exterminator for professional help. Additionally, you can use sticky traps or a bed bug detector to help you determine if bed bugs are present in your home.
