Wayne County, Detroit Rat Control Situation:
Please can you offer me some free practical advice to eradicate rats from my roof space, I am English but now reside in Brazil. Here in Brazil there are no such associations, councils to exterminate vermin, the only choice is either to employ local labour and hope he is being truthful about his qualifications, quality of workmanship, formal training etc. or to do the job properly do it yourself. For several months I have heard pattering of tiny feet in my roof space, the roof space being the area between the bottom of the tiled roof (pantile type tiles) and the top of the plastic false ceiling with only about 4 inches, 100mm in between so snap traps are not practical, I live in the apartment directly below the area contaminated and have not seen any rat droppings in the apartment, the area is approx 9 meters x 15 meters =126 square meters , 29ft x 49ft = 1421 square feet. The apartment is a first floor level approx 4 meters= 13 feet from ground level with no adjoining buildings. Am I correct in assuming that the rats enter up through 4 inch, 100mm plastic rain down pipe from the roof guttering? or up through the toilet sewage system through the u bend in the bowl and then climb a wall to enter the roof space, or do the rats scale the outside 12 meter = 39 feet wall and enter the roof eves. I am considering to remove all the plastic false ceiling to gain access to the infested locations but am concerned firstly that if I disturb the rats they will disperse and then return the same way they originally entered the area, secondly, if l remove the false ceiling will l be the unlucky victim to receive their bite, what do you suggest I do? Poison the visitors first? then if quiet after a week or two remove the ceiling and completely sterilise? (with what can you recommend). I am not concerned with the humane topic of eradicating my guests, they pay no rent. (KK KK ). Also it is my intention to fully enclose the rafters and eaves on the outside with either aluminium or galvanised steel mesh. If you can take time out to advise me, I will be very grateful. For your information a cross section sketch of my roof is enclosed to help you understand the constructional theme of my roof. Would it be practical to remove the plastic ceiling room by room, first destroying the nests if any, then sanitising ,sealing all access points of entry, then to move to the next room etc.? I would really appreciate any advice you would furnish, unfortunately I can not afford to pay your expenses etc. for you to submit a quotation, I can offer you though if you ever visit Brazil a nice glass of cold Chopps (Brazilian draught beer). Fondest regards and in anticipation of a reply many thanks.
My response: Yes, your plan to seal off the roof with galvanized steel mesh should work. But you have to seal 100percent of the openings. Then, trap, properly trap on rat runways, ALL the rats, and remove them from the house.
Detroit Rat Control Tip of The Week
City Subways And The Presence Of Rats
Rats, like pigeons, badgers, and foxes thrive in urban environments, even moving to these places. Cities are full of garbage dumps, abandoned lands, and sewers that can provide a cozy burrow for rats to live in and raise their families. Human beings have provided the perfect conditions for the well-being of this species.
Sewers And Rats
Sewers can provide everything needed for an exponential multiplication of rodents. The problem is that the more rats there are, the more they need food, so to get it they will be severely aggressive towards each other. This aggressiveness and the search for new food sources can cause serious damage to the city.
Rats Are The Real Infection
These rodents are known for carrying bacteria that cause infectious diseases leading humans to death. Something similar occurs with rats when they spread through sewers, subways, garbage dumps, and train tracks.
Rats survive thanks to the mountains of garbage in the city and play a vital role in reducing this waste. However, wiring or holes and infrastructure problems can be just some of the catastrophic consequences for the city's subway system.
Super-rats
Humans love junk food and in big cities, high-calorie garbage has given the rats that eat it the energy they need to grow exorbitantly even creating resistance to some rat poisons.
The well-being of citizens begins with professional pest control combined with a mind-set of not throwing garbage into the environment. Briefly, if there is neither food nor garbage, there are no rats. The fewer rats there are in places like the subway, the fewer rats will be able to reach homes. The more we take care of the city, the fewer health problems or economic damage there will be.
