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
Norway Rat Biology
The Norway rat is typically nocturnal. It is a good swimmer; however, unlike the related black rat, it is a poor climber. Norway rats burrow well, and regularly uncover broad tunnel systems.
Rats are equipped for creating ultrasonic vocalizations, both as grown-ups and babies. They may likewise transmit short, high frequency, socially-prompted vocalization during interaction with different rats or animals. This call most takes after a trilling sound but is undetectable to human ears. Rats can discernibly be heard through calls sounding like squeaks when they are in trouble.
These rats are omnivores. This implies they can eat both plants and animals. As predators, rats are opportunistic.
The Norway rat can breed consistently if the conditions are reasonable, and a female can deliver up to twelve litters in a year. The gestation period is just 21 days, and litters can number up to fourteen, albeit smaller litters are common. In this way, the rat population can increase rapidly. Rats have a lifespan of around three years, yet regularly live less than one year.
Norway rats live in enormous hierarchical groups, either in tunnels or subsurface places, such as sewers and basements. When food is hard to come by, the rats lower in the social order are the first to die. If a large portion of a rat populace is eliminated from a zone, the rest will expand their reproductive rate, and rapidly reestablish the old populace level. This makes it imperative to have a plan to get rid of the entire rat population on your property if an infestation occurs.
