DC County, Washington DC Rat Control Situation:
I am a double heart transplant/cancer patient and not in good health. I have discovered a huge hole on the outside of my home, which is allowing critters in my attic. I do not know what they are, but possibly roof rats. Their presence could very well kill me, since I have no immune system to help me fight bacteria. I would like to know the cost of removal & repair of the area which they have ruined on the side of my home. I am a senior citizen who can no longer work and have little disposable income to pay much, since my medical bills are so high. Is it possible to get an estimate for this & also a time frame from when it can be done? I spend a lot of time in the hospital and just finished a 3 month stay, which included another cancer surgery. I live in Washington DC. My phone does not ring in properly, in fact, gets poor reception, same as my Internet service, but they blame it on my area. So please use my email when possible. I would appreciate a reply ASAP. Thank you very much. J Hill
My response: The presence of rats won't kill you.
Washington DC Rat Control Tip of The Week
Will Rats Come Out When It's Light?
Rats are living beings with a negative phototropism. Daylight often affects them, leading them to be most active when it's dark out. Most rodents are characterized by going out during evenings when there is dim light or at night.
This habit of being active at night is very useful when combined with the instinct of going unnoticed. Rats that live in underground places like sewers can suffer retinal damage when they surface in broad daylight. The discomfort to their vision does not allow them to carry out the necessary daily survival activities.
Light is an abiotic environmental factor that can have a major impact on animal behavior and physiology. Rats adapt better to darkness because it can be very comfortable. It is believed that rats have dichromatic color vision and light is often a very important environmental signal for regulating circadian cycles and reproduction cycles.
Fear Of Light Or Fear Of Death?
Rats are one of the most successful invasive species in the world, they can adapt to almost any environment. These animals perceive light as dangerous. The light rays can make rodents feel somewhat exposed to predators or even vulnerable to people who will want to exterminate them no matter what it costs.
A Messy And Damp Place Is Ideal
Abandoned buildings, homes with cracks in the walls, or sewers, often have an abundance of dark places. A home with little light is ideal for living; it is perfect for rats to make their nests without having to expose their small offspring to being eaten by other animals.
Professional exterminators often use this information about the light phobia of rats in their preventive or extermination plans. The ultimate goal is to prevent these rodents from making their dens in or near people's homes.
