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.

Reasons Why Relocated Rats Don't Survive Out Of Their Usual Territory
After trapping a rat in your home, you will have to decide either to kill it or relocate it. If killing a rat doesn't go down well with you because it makes you feel inhumane, you will be left with no other option but to relocate it.
If you have decided to relocate a trapped rat into a new territory, you need to understand the fact that it might not survive. Despite being a very smart household pest, rats find it very difficult to cope in a new environment for several reasons. The following are the reasons why a relocated rat won't survive out of their usual territory.
The first reason why rats won't survive in a new environment is that they are accustomed to their old environment. They have spent their entire life studying where they stay, knowing the exact place to find water and food in order to survive daily. Transferring this survival instinct to a new environment is a quite difficult thing to do for rats. As a result of these differences, they will find it difficult to locate food and water which they need to survive in any environment they are relocated to.
The presence of predators in the new environment is another reason why rats will find it difficult to survive. Animals like cats, snakes, and birds hunt for rats and will take advantage of the fact that the newly introduced rat doesn't know its way around to capture it.
When you introduce a rat into a new environment, it is going to meet other street rats that are already accustomed to that specific environment. Rats being animals that exhibit dominance in the form of hierarchy, where the submissive group is traumatized by the dominant rats, your rat will face multiple brutal battles and might end up in bad shape in the process. Over time, they will either get killed or too weak to look for food and shelter.
All these clearly show why any rat you decide to relocate might never survive the effects of leaving your home and being transferred into a new environment.
