Common Entry Points Showing What Attracts Bed Bugs Into Your Home
Below are some common entry points showing what attracts bed bugs into your home:
1. Luggage and travel bags: Bed bugs hide in suitcases or folds, crawling quietly into clothing or linings. After a trip, they enter your home, drawn by human scent and warmth.

3. Cracks in walls or baseboards: Gaps between floorboards, wall joints, or baseboards allow crawling entry. Bed bugs slip through micro-crevices toward attractive human hosts.
4. Electrical outlets, switches, wall openings: Behind outlet plates and switch boxes, bed bugs migrate through wall openings, drawn toward wiring that emits warmth near people.
5. Shared walls in multiunit buildings: In apartments, bed bugs travel across wall holes or via pipes and lines, especially when they sense CO₂ and heat from neighboring units.
6. Clothing, handbags, backpacks: Bed bugs cling to garments or bag straps, then transfer to your closet or inside rooms, following human scent trails and temperature gradients.
