If you notice dark spots on your bedsheets or mattress, it’s likely that bed bugs are causing them. To treat bed bug stains, you can apply an enzyme-based stain remover or a solution of peroxide and ammonia. Make sure to avoid applying heat to the stained fabric. Also, use a flashlight to spot any bed bug eggs. Bedbugs typically lay their eggs in clusters, so you should be able to find them easily.
If you have a suspicion of bed bug infestation, you may notice brown or black stains on your mattress. These stains are the feces of bed bugs and can be hardened over time. They look like dark stains or an ink mark on a sheet. They also contribute to a rusty odor.
Bed bugs live in the seams of a mattress, feeding on unsuspecting humans as they sleep. These bugs leave a dark spot on the mattress when they feed on human blood or excrement. Some people may also notice rust-colored spots, which may be bedbug excrement.
Another way to identify bed bug infestation is to smell the mattress. Bed bugs secrete chemicals to communicate with each other, so they may leave behind a faint odor. If you notice these signs, you may want to remove the mattress.
