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 I Inspect My Home For Rat Entry Holes?
Rats can be tough to manage when they get access to a property. Their population will increase quickly and they will cause a great deal of harm to pretty much everything chewable insight. Truly, they lead to a major issue for homeowners, yet their activities can be controlled and they can be removed if managed properly.
It is of the most extreme significance while dealing with a rat infestation to identify their entry points and block them. Otherwise, they will return every time you try and expel them. Investigating a house for rat passage openings can be cumbersome as the list of spots to check is seemingly endless, especially when the house is big.
Attics, space vents, dividers, kitchens, cupboards, soffit vents, pipes, roofs, rooftop vents, etc. are some of the spots to assess. The following will help you in doing an exhaustive investigation of your home.
1. Have Fundamental Information On Rat Science
Information on their nature, habitat, appearance, diets, and behavior will help you figure out where their entry points are likely going to be in your home.

This also is significant. Finding out about the house's plan would help identify those shrouded spots where openings may exist in parts of the house, and these gaps might serve as rats' openings.
Having watched every one of these, property holders must check everywhere, including foundations, vents, rooftops, soffits, and so on. Anyplace there is a gap, regardless of how little it is, is a potential entry point. It may surprise you that rats can enter through holes as small as a quarter of an inch.
