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.

What Is The Natural Diet Of The Black Rat And Norway Rat?
Black Rat
The black rat (in many cases called the ship rat) has a smooth and incredibly long tail that is longer than its head and body. Romans were the ones who brought this species to Britain. The color of the black rat fluctuates from dark to grey-brown. When compared with brown rats, these creatures have little bodies and bigger ears and eyes. Black rats are amazing climbers. They are fit for running along phone wires, utilizing their tails to adjust while moving. The species is additionally called 'rooftop rat' due to building their homes high in rooftop spaces.
Diet
Black rats are viewed as omnivores and eat a wide scope of foods, including seeds, natural products, stems, leaves, fungi, and an assortment of invertebrates and vertebrates. They are generalists, and as a result, not picky on their food choice, which is demonstrated by their propensity to benefit from any meal given to cows, pigs, chickens, felines, and dogs.
Norway Rat
The main thing to know is that, regardless of the name, the Norway rat isn't really from Norway. It is believed that the name originated from a man named John Berkenhout, a British naturalist, who concluded that the brown rats had migrated to the UK from Norway. Present-day researchers think that this type of rat actually originates from China. They showed up in the British Isles most likely transported via ships and goods.
When they got to the UK, be that as it may, they immediately multiplied and set up for business there. That is the reason they are otherwise called the common rat, the road rat, the sewer rat, or the brown-colored rat.
Diet
Norway rats will eat pretty much anything. If they get inside, they'll search in your kitchen cupboards and pantries. Specifically, the rats are looking for meat and even fish; however, they will also feast cheerfully on dry dog food. When they discover the food, they will eat and eat, glutting themselves on what they find, and if they smell food, they'll chew through plastic, lead pipes, wood, and anything else to get there.
