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.

How Do Wildlife Rehabilitators Deal With Rats?
Even though rats do cause a nuisance in homes, they also need to be treated humanely when indisposed. In a situation where you find a stray and injured rat in your home, the best thing you can do is to contact a wildlife rehabilitator to help evacuate the rat immediately. While waiting for the rehabilitator, you need to avoid any physical contact with the animal, as rats are often carriers of different kinds of pathogens and diseases.
Wildlife rehabilitators are licensed professionals that help to evacuate animals from people's home, treat them if they have health issues, and release them back into the wild. Unlike other animals, wildlife rehabilitators handle rats specially.
Since stray rats do find it very difficult to survive on their own if relocated into the wild immediately, the first thing wild rehabilitators do is to nurture the rats for days or weeks to ensure that they are in good health. To do this, the rats are introduced into a box filled with woodland debris to make them feel comfortable and are properly fed with good food. This nurturing process continues until the rats can survive on their own without the help of anyone.
After successfully nurturing them, the wildlife rehabilitator can then go ahead and release the rat back into the wild. The release of the rat into the wild is not just done indiscriminately. Wildlife rehabilitators look for areas with a possible place of shelter for the rat with an abundant source of food.
Wildlife rehabilitators make sure evacuated rats stand a chance of living. Therefore, don't hesitate to contact a wildlife rehabilitator if you have stray, injured rats in your home.
