Rats in Houston Homes: A Troubling Intrusion

Houston, Texas, with its bustling urban environment and warm climate, unfortunately, provides an inviting habitat for a variety of pests, including the common house rat (Rattus rattus), also known as the roof rat, and the Norway rat (Rattus norvegicus). These rodents, known for their prolific breeding and ability to cause damage, can become a serious concern when they invade homes in the area.


Rats come in different species, including the roof rat and the Norway rat, each with distinct characteristics. Roof rats are sleeker, with long tails and ears, while Norway rats are bulkier, with shorter tails and smaller ears. Both species typically measure around 6 to 9 inches in length, not including their tails.


Roof rats are adept climbers and often inhabit elevated areas such as attics, roofs, and trees. On the other hand, Norway rats are more ground-dwelling and tend to burrow in basements, crawl spaces, and along building foundations. Despite their different habitats, both species can infiltrate homes, seeking shelter and food.


Rats are primarily nocturnal, meaning they are most active during the night, foraging for food and exploring their surroundings. They have a keen sense of smell and are attracted to food sources, which can lead them into homes in search of sustenance. Both roof and Norway rats are prolific breeders, with females capable of producing several litters per year, each containing multiple offspring.

Health Risks

Beyond property damage, rats pose significant health risks to humans. They are carriers of various diseases, including leptospirosis, hantavirus, and salmonellosis, transmitted through their droppings, urine, and saliva. Inhaling airborne particles from contaminated areas or coming into direct contact with rat excrement can lead to serious health complications.

Control and Prevention

Preventing and controlling rat infestations require a multi-faceted approach. Start by sealing off entry points, such as gaps around doors, windows, pipes, and vents, using materials like steel wool or caulk. Keep indoor and outdoor spaces clean and clutter-free, eliminating potential nesting sites and food sources. Traps, baits, and rodenticides can help reduce rat populations, but proper placement and handling are essential to ensure effectiveness and safety.

Professional Assistance

For severe or persistent infestations, seeking professional pest control services is advisable. Pest control experts have the knowledge, experience, and specialized equipment to assess the extent of the problem and implement targeted solutions tailored to the unique needs of each home. They can also provide valuable advice on long-term prevention strategies to minimize the risk of future infestations.

Rat infestations are a common concern for homeowners in Houston, TX, but with vigilance and proactive measures, they can be effectively managed. By understanding the habits of roof rats and Norway rats, addressing conducive conditions, and implementing appropriate control methods, residents can safeguard their homes, health, and peace of mind from these troublesome intruders.
