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 Equipment Do I Need To Trap A Rat?
Trapping a rat is not as difficult as it seems, provided you have the right kind of equipment. Rats are a highly intelligent household pest with prior knowledge of your unyielding intentions to either get them killed or captured. As a result of this, they will try as much as possible to run for their lives whenever they get the chance to.
For you to outsmart them and make your plans to trap them successfully, you need good quality traps set up at the spot the rats in your house pass through the most and the right process of setting these traps.
Have you decided to trap the rats in your home and you are looking for the equipment to use and the right way to go about this? The first thing you have to do to achieve your objective is to discover the exact routes of the rats in your house. These are the places you will be setting your traps once you are ready to capture them.
After that, the next thing you have to put in place is the right kind for bait. A good bait should help attract rats and not any other pest or animal in your home. If you just chose a random food substance as bait, you might end up trapping the pets in your home instead of the target pest.
After putting all of that in place, the most important piece of equipment you need to trap a rat is a good quality trap. Your choice of trap depends on whether you want to kill the rats with the trap or just trap them and later release them far away from your home.
If you choose to kill them directly with the trap, a lethal rat trap will be most appropriate. The only issue with the use of this trap is that you will have to get multiple traps and set them at different locations because this kind of trap can't trap more than one rat at a time.
On the other hand, if you choose to trap the rats and release them afterward, a one-way entry door trap will also be most appropriate. Also, while setting up either of these traps, you need to protect yourself at all times from the bacteria spread by the rats by wearing a pair of gloves and a protective mask.
