What is a rat infestation and why is it dangerous?
A rat infestation occurs when these rodents find food, shelter, and constant access routes inside homes, businesses, or other spaces. Although many think it only happens in neglected areas, the reality is that rats adapt quickly to urban and commercial spaces, especially near kitchens, warehouses, or areas with food waste.
What makes a rat infestation truly dangerous is that these animals not only cause property damage by gnawing on wires, wood, or insulation, but they also carry diseases, such as leptospirosis, salmonella, or hantavirus, which can be transmitted to people and pets.
Common Signs of a Rat Infestation
Detecting a rat infestation early is key to preventing bigger problems. There are several visual and auditory signs that can indicate their presence:
- Drops: small, dark, rice-like segments found around pantries, baseboards, or dimly lit corners.
- Gnawing marks: jagged edges on wires, furniture, or storage boxes.
- Strong odors: a persistent, unpleasant smell in enclosed areas can be a sign of an infestation.
- Nighttime noises: creaking or movement behind walls and ceilings at night.
- Footprints and trails: Traces of plaster or flour dust strategically placed that reveal frequent routes.
Even if you only notice one of these signs, it’s advisable to act quickly.
How to prevent a rat infestation
Prevention is more effective than dealing with an established infestation. Some practical tips include:
- Seal entry points: Plug cracks in walls, floors, or around doors and windows.
- Control waste: Keep garbage cans closed and remove waste regularly.
- Order and cleanliness: Don’t accumulate boxes, pallets, or materials that could serve as hiding places.
- Avoid exposed food: Store food in airtight containers and clean up any leftovers immediately.
These measures reduce the likelihood of rats finding a reason to settle in your space.

What to do if you suspect a rat infestation?
If basic measures don’t eliminate the signs of an infestation, or if the infestation appears advanced, it’s best to contact professionals.
