How to Prevent a Bed Bug Infestation

If you’re concerned about bed bugs infesting your mattress, you can take several steps to prevent them from settling in your bed.

These dark mattress stains are from bed bugs.

Identifying bed bugs is not always easy. They are small, nocturnal pests that feed on the blood of humans and animals while they sleep. Not only can they be hard to spot because of their size, but they also hide in cracks and crevices during the day making detection even more difficult.

To identify an infestation, look for these signs:

• Small brown spots or stains on mattresses, sheets, and other surfaces where bed bugs have been feeding.

• Shed exoskeletons and dark spots of bug excrement on bedding, furniture, or carpets.

• Live bugs, eggs, or nymphs in the creases and folds of mattresses and bedding.

• Tiny white eggs which may be stuck to fabric fibers.

If you suspect an infestation and are unable to control it yourself, a professional can help you. Pest control companies use pesticides that contain pyrethrins or pyrethroids to control bed bugs.
