Madison County, Huntsville Rat Control Situation:
Hi David, I found your website online -- very informative for removing rats and squirrels from attics. My problem is the animal(s), which I'm guessing are rats or mice because they only scratch at night, is in the ceiling, but there is no attic or crawl space. The structure is a two story condo and the scratching sound is in the same location for the past 2 - 3 nights: in the ceiling of the small landing between the two upstairs bedrooms. There is a recessed light in that ceiling, and removing the light cover does provide a small access into the ceiling. The actual hole is about 6 - 7" wide, but there is an old-style light can in the hole, which only has a few small openings in it. Last year prior to painting the ceiling we removed the light cover and down came some animal droppings. Even though we weren't hearing any animal noises at that time, we set two Victor mouse traps which we were able to fit inside the small openings. We didn't catch anything so eventually, we just put the light cover back on. Now, there is very active scratching in the ceiling a few inches from the light so there is definately something alive in there. If it's a mouse, we can probably set a trap like we did before and I believe there is enough of an opening to remove the trap with a mouse in it. If it's a larger critter like a rat, we may or may not be able to set the larger trap and/or remove the trap with the dead animal because the opening may be too small. Even if we are successful at trapping and removing the animal, there is little access to remove the droppings or see if they've done any damage in there. Any suggestions you have would be greatly appreciated. Thanks. Nicole in Huntsville AL
Between floors is hard. If you can get a trap inside, great. You still need to Inspect the house and find out how the rodents are getting inside and seal up every single last entry/exit hole and gap with steel.
Huntsville 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.
