The Bottom Line on Rats...
The City of Chicago recognizes that Chicago has a rat problem. But the administration does absolutely nothing that will stop it. Not on your block, nor on anyone else’s. The steps that the City has taken – lidded trash containers and attempts at rat abatement in alleys – are nothing more than papering over the problem.
The City also continually underestimates the scope of the problem. In brochures distributed city-wide, our Mayor, Richard M. Daley, declares that although there were over 6 to 8 million rats within the City of Chicago within the last 20 years, now there are less than 500,000. These same brochures have been out there for public consumption for a number of years, using the same numbers. But 500,000 rats should, conservatively, in any given year, breed nearly 12 million mature rats. For the City estimates of 500,000 rats to be accurate from year to year, 11.5 million rats would have to die each year. That mortality number is laughable, particularly given the inadequate steps taken by the City to solve the rat problem.
In short, the rat population estimates that have been repeatedly presented as factual are simply bogus.
Why are the City’s efforts not sufficient?
The primary effort, the alley abatement program, cannot work as the program is formulated. For the most part, the City will not enter anyone’s property to do rat abatement unless they receive permission from the property owner. But access to property adjacent the alley is necessary to properly bait alleys.
Even then, the rodent crews cannot address the difficult to reach rat travel areas within the sewer systems, both private and public.
Streets and Sanitation will, when requested by a neighborhood group, will send out rodent crews to examine a property or multiple properties. They will place bait in rat burrows, and will inspect yards and garages, but they will never publicly identify a reason for rat presence that comes up from the city’s infrastructure.
Our many years of experience with rat calls from customers throughout Chicago has shown to us that 9 out of 10 calls about rats on a property are generated from the sewers (drain pipes, etc.) on private property, which the rats access from the public sewer system.
The other 1 out of 10 situations occurs in unkempt neighborhoods that show no regard for sanitation within or without their homes. This condition would be found in low income tenement housing where there is little or no owner occupancy.
What can you do about it?
American Eagle Pest Elimination offers a two pronged approach that will achieve the permanent elimination of rats. First we identify and eliminate the existing populations, and then we propose structural corrections that will prevent rats from relocating to your property in the future. We will guarantee the permanent elimination of rats if the property owner permits our company to maintain annual property inspections subsequent to the correction work.
Sometimes, however, you and your neighbors have to be willing to solve the problem together. We also offer a neighborhood block inspection for any block within metropolitan Chicago for a nominal fee which will accurately identify the source of the rat problem and how the rats arrived on the block. Once we identify the specific source of the rat problem, and if it is indeed on private property, we work with the individual property owners on a fee-for-service basis to permanently resolve the rat problem. [American Eagle describes one city block as the buildings whose properties back up to a given alley.]
 Females are reproductive at four months and male rats at three months old. Figuring that a four month old female rat would produce 58 babies of which half would be female, in one year, by exponential growth, production could be as follows:
In April, 28 females would produce 112 females. In August, 448 females would be birthed, and in December, 1792 females would be born. We believe that we would add 1 + 28 + 112 + 448 + 1792, for a total of 2381 female rats including the first four month old female. Let’s consider that twice this total could be both males and females at 4762 rats.
It is likely that 50% of the total offspring, males and females, would not survive their first year. We took half of the total population estimated; thereby, using 2381 rats as the base maturing number.
