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 Do Rats Use Pheromones To Communicate?
Releaser Pheromones:
Rats communicate using releaser pheromones to send information to other rats that they are in their own territory. Rats often urinate in areas to send information that they are ready to nurse or that a specific area where their nest is located is their own. Rats use these releaser pheromones to claim territory and to make sure that other rats will stay away.
Primer Pheromones:
Primer pheromones are designed to be excreted during the peak of fertility and this is the type of pheromone that sends sexual signals to males in the area. These scents are released in order to attract males and to make sure that the female is going to mate during a time where she is more than likely to conceive.
Primer pheromones are some of the main types of communication tools used by rats and it's one of the most powerful ones that can be sensed in the area. These responses are triggered by the area of the brain called the Vomeronasal and this refers to the overall sense that an adult male gets of the pheromone.
Information Pheromones:
These types of pheromones are designed to be useful for identifying something about the animals or about the area. Rats often use these to convey fear or to share information about an area. Certain species of rats can share information about a food source, safe space, and more with these types of pheromones. Most of the time informational pheromones are designed to identify the smell of other species and to warn other rats of dangers in the area.
Scientists are continuing to study rats to determine the total number of ways that they are able to communicate by pheromones alone.
