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
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.
