Wake County, Raleigh Rat Control Situation:
How can I tell if I have rats or mice hanging out in my walls/attic? We haven't found any signs of anything getting into the main part of the house, but every once in a while we hear them scurrying around in one spot. We only hear them in the evening, and we haven't heard them very often (tonight is the first time I have noticed them in two weeks, but I'm also not home every evening). First we thought it was mice, but I am starting to worry that they might be rodents nesting for the winter. I checked outside and couldn't find any visible entry points, nor any footprints on the roof. I also looked under the roof overhang on that side of the house and there are no holes there. I can't tell if I am hearing squirrel chirping or mouse squeaking--it's almost a squeak-like chirp (real helpful, I know). If we can't find any holes for them to get in, it makes me think mice, but if we haven't seen any signs of them in the house and only hear them in one spot, it makes me think squirrels. Whatever it is has had access to this spot for quite some time, so if they are rats, I think we need to act ASAP, as per the damage reports I've seen on websites. Any and all advice you have to diagnose what we are dealing with would be greatly appreciated! Thanks for your help! - Kristin
My response: Sounds like mouse or rat activity to me. Squirrels are active in the daytime, and people usually hear a lot of morning noise. If you inspect the attic, you can tell by the droppings left behind.
Raleigh Rat Control Tip of The Week
What Are The Mating Habits Of The Black Rat And Norway Rat?
Black Rat
The ship rats have a polygamous mating framework, where a single male mates with various females. As a rule, the prevailing male is a successful breeder. These rats mate from March to November. The development or conception period goes on for 21 - 29 days, yielding 3 - 5 litters of 1 - 16 young (with a normal or average of 7) every year. Children of this species are brought into the world altricial. Their eyes open just at 15 days old, while hairs show up before the end of the nursing period. The young ones are weaned, and become independent at 3 - 4 months of age.
Norway Rat
Norway rats generally build homes in below-ground burrows or at ground level. Homes might be fixed with shredded paper, fabric, or different stringy materials. Litters of 6 to 12 young ones are brought into the world 21 to 23 days after conception. Baby rats are stripped, and their eyes are shut; however, they develop quickly. They can eat solid food at 2 1/2 to 3 weeks. They become independent at around 3 weeks to about a month and arrive at reproductive maturity at 3 months old, sometimes as early as 8 weeks. Female Norway Rats may come into heat every 4 or 5 days, and they may even mate a day after a litter is conceived. The average female rat has 4 to 6 litters per year and may effectively wean at least 20 offspring every year.
