Knox County, Knoxville Rat Control Situation:
I own a 2 story w basement corner row house in Knoxville. Last night while asleep on the couch in my first floor living room, noise in my ceiling by the front wall woke me up. Sounded like the scurrying of 1or 2 mice. Joists run the width of my house, from the outer wall to my neighbors house, so that space leads to nowhere. No food, water, or other openings are available. Should I be concerned, should any (?) action be taken?
One story concrete slab house with rats in attic. I have sealed up every hole to the attic I can find. The last thing I did was put the 1/2" wire mesh on all the vent pipes on the roof. The wire mesh on all the stacks, seemed to fix my problem, but about 2 months later they are back. I put up some security cameras in the attic and at bottom of a double wall space for plumbing, and can see the rat coming down and going up at bottom of a 2" pvc vent pipe obscured by a wall between two bathrooms with a tub on one side and shower on the other. The vent pipe is for the tub and shower. From the top of wall in the attic, I was able to cut out around the pipe and see down the wall about halfway down the 2" pvc vent was split (offset) maybe broke during construction where 2 pipes were joined together. Could not see actual chewed off part, but is probably there. I can see that the rat could get in there, but my question is where or how is he going outside besides into the sewer? The top is sealed with the wire mesh. I can fix the split pipe easily by tearing out the shower wall, but do you think that would fix the entry problem? How long can rats stay in attic without going outside for food? Do attic rats tunnel under a concrete slab house for entry?
Knoxville 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.
