About Bed Bugs

Bed bugs are small, flat, reddish-brown insects about the size of an apple seed (4-5mm). They're nocturnal parasites that feed exclusively on blood, preferring humans. Adults can survive up to a year without feeding. They don't fly but crawl quickly and can easily spread through luggage, furniture, and clothing. Bed bugs hide in cracks, crevices, mattress seams, and furniture during the day. Their bites often appear in clusters or lines and can cause significant discomfort and anxiety. Infestations have increased dramatically in recent decades due to increased travel and pesticide resistance.

Identification

Adults: 4-5mm long, flat, oval, reddish-brown. Nymphs: smaller, lighter colored, translucent until they feed. Eggs: tiny, white, oval (1mm). After feeding, bodies become elongated and dark red.

Signs of Infestation

Red or rust-colored stains on bedding from crushed bugs. Tiny dark spots (fecal matter) on sheets, mattresses, or walls. Sweet, musty odor in heavy infestations. Actual bugs in mattress seams, headboards, or furniture. Shed skins from molting nymphs. Itchy bite marks in lines or clusters.

Health & Safety Risks

Bed bug bites cause itchy welts and can lead to secondary infections from scratching. Some people experience allergic reactions. Infestations cause significant psychological distress, anxiety, and sleep deprivation. They don't transmit diseases.

Prevention Tips

Inspect second-hand furniture before bringing home. Use protective mattress encasements. Reduce clutter in bedrooms. Vacuum regularly. Check hotel rooms when traveling. Keep luggage elevated and away from beds. Wash and dry bedding on high heat regularly.
