Bed bugs are insects that feed on blood (mainly human) and hide in seams, cracks, and furniture. The main challenge is that they're experts at hiding and can spread through luggage and furniture.

Scientific name
The best-known bed bug is Cimex lectularius (family Cimicidae). Different regions can have closely related species; in practice, the inspection and control approach is similar: find hiding spots, limit spread, and treat critical points.
What locals call them in Costa Rica
In Costa Rica they're called chinches or chinches de cama (bed bugs). Many people confuse them with fleas or other insects because of the bites; confirming it really requires an inspection (look for signs on the bed and furniture).
Where they're found in homes
- Mattress: seams, tags, folds, and edges.
- Bed frame: joints, screws, corners, headboards.
- Nearby furniture: nightstands, sofas, recliners (seams and frames).
- Cracks: baseboards, door and window frames, outlets (behind the cover plate), picture frames.
- Luggage: suitcases and bags stored near bedrooms.
Conditions that favor an infestation
- Arriving through travel: trips, hotels, visitors, moves, buying used furniture.
- High guest turnover in lodging: makes it easier for them to come in with guests.
- Clutter: more hiding spots and a harder inspection or treatment.
- Partial treatments: if you only spray "where it bites" without treating the hiding spots, the population holds on.
Typical signs
- Small black spots (droppings) on seams, edges, and wood.
- Reddish stains (blood) on sheets.
- Shed skins (exoskeletons) near hiding spots.
- A sweet, musty smell in heavy infestations.
Note: bites alone don't confirm bed bugs (they could be mosquitoes, fleas, or allergies). Real confirmation comes from finding physical signs on the bed or furniture.
Prevention (travel and furniture)
- When you travel, check the mattress seams and headboard; don't put your luggage on the bed.
- When you get home, inspect your luggage and wash your clothes using the right protocol for the fabric.
- Don't bring used furniture into the house without a thorough inspection.
- Cut down on clutter in bedrooms so it's easier to inspect.
Professional control
Professional control is based on an inspection (to find hiding spots), a zone-by-zone treatment (bed, perimeter, nearby furniture), and steps to reduce spread. Some cases need multiple visits, because certain life stages can survive an incomplete treatment.
