Kings County, New York City Rat Control Situation:
Hi, I found your site very informative and helpful. I live in a ground floor duplex in New York City and we have had a rat problem in between our two floors since last August. The management company has sent an exterminator out several times-- to remove carcasses from the ceiling, place rodenticide in the ceiling, and fill any holes outside the apartment building. The problem is still going on almost a year later and we can't seem to figure out how they are getting in.
There is definitely less scratching and scurrying now compared to a few months ago, but the smell is consistently unbearable as something dies in the ceiling every few weeks to the point that I am ready to just move out. I have asked the management company to take a more proactive approach to the problem rather than reactive when I call and complain, perhaps gut the ceiling to expose the problem area, but they don't seem willing to do it. I can imagine there are a lot of droppings and urine in addition to at least 3-4 dead carcasses. Would the smell disappate if no more rats could get in (i.e. if we found and closed the access points), or is that something that will just continue to fester?
I am trying to make a case to the management that it is necessary for them to clean all the droppings and carcasses to restore the apartment to a sanitary environment. I noticed on your site you mentioned that rats can smell the droppings and urine of other rats, indicating the area is a safe habitat. I also think opening the ceiling might expose the access points. Apparently my unit is the only one of 47 in the building with a reported rat problem. Do you have any suggestions? Best regards, Alexandra
My response: Sounds like a very tough case. The entry holes into the building, or at least, the apartment, must be found and sealed! Check behind the oven, for example. The odor will disappear as soon as all rats are gone and any biomass dries up.
Thanks for the response! I got them to remove the entire ceiling and they said they removed some carcasses and closed a bunch of holes inside. I was on a business trip the past week and will see the result tonight. Fingers crossed the problem is resolved!
New York City Rat Control Tip of The Week
How Likely Is It That A Rat In The Attic Will Have A Nest Of Babies?
Rats are among the most common pest animal species that people may have to deal with around the home, and because they are quite small they can often be quite elusive little animals to deal with as well. They are quite good climbers when it comes to moving around a domestic property, so if you are worried about rats, they won?t necessarily be around ground level. Because the attic or roof space of most domestic properties is rarely used, it can often be the dark quiet place where rats can get a foothold and build a nest without being noticed by the people living beneath.
Do Rats Have A Mating Season?
Like most wild animals, rats in the wild do have a mating season, where they will normally copulate and impregnate female rats in the spring, and then the female will then give birth a few weeks later, and can then have a few litters over the summer. However, the reason for the mating season is that in rural areas there are limited food sources available during the winter months, so it is impractical for rats to mate during these months. However, over recent decades, a growing number of rats are actually giving birth throughout the year because food sources are also present throughout the year, so whatever time of the year you discover rats in the attic, you may find there are babies there too.
How Often Will Rats Give Birth?
Because of how quickly rats can go from mating to giving birth to a litter of baby rats, a female rat can often be back and ready to mate again within a few weeks from giving birth. This means that in some cases female rats can give birth to up to ten litters a year, so the population of rats from one breeding female can increase very quickly. It is also worth noting that a baby female will actually become sexually mature herself after around six weeks from birth, so the possibility for a rat population to expand very quickly where there is sufficient food is certainly there.
Dealing With Rats In The Attic
When it comes to dealing with a rat infestation, the first step is to identify where in the attic the rats are active, and while taking the appropriate precautions, look for areas where there is a buildup of rat droppings. You should then place several rat traps in these areas of the attic, along with a small amount of food as bait, and the next step is simply to watch and wait. You should remove any rat carcasses as they are caught in your traps, and then re-lay the trap with a new serving of bait, and you should then continue this process until you no longer see any signs of fresh rat activity, and when you are no longer catching any more rats. You will then need to carry out the appropriate repairs.
What To Do With A Nest Of Baby Rats
In some cases you may actually find a nest of baby rats in the attic, and if they are very young they will often be unable to look after themselves, and will ultimately die if they have to live without the support and feeding from their mother. Because of how common they are, baby rats are rarely suitable to be looked after by a wildlife rehabilitator, so in this case the most humane thing that you can do will be to kill those baby rats as humanely as possible.
