Brevard County, Melbourne Rat Control Situation:
David, I have trapped 3 roof rats in the attic and have heard more this morning chewing and romping about. I have sealed all entries I to the house with exception to drain stacks on roof. I can see feces in gutters but cannot see anywhere where they could be getting into the attic. I have been working with an exterminator for two months and he's out of ideas so I was wondering what advise you may put forward. Sure would like to get rid of them for good prior to breeding season. I am in Dallas Tx area. Last December our dog caught o e in yard, this summer I caught one in shed, and I caught one in attic and pro has caught two ... But like I said there appears to be more. We have a two story stucco house in Melbourne FL. Over the past 3 years I have caught at least 30 mice in our attic, all the while searching diligently and unsuccessfully for the entry point(s). I found a few possible places and have closed them off but still catch one or two a week. I am completely stumped on this. They are only in the attic as far as I know. We do have a dryer flap-vent in a below grade window well but that leads to the basement and we don't see them there. Is there any new "scientific" way to identify entry points? Advice appreciated pls -- Matt
Melbourne 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.
