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.
Detroit Rat Control Tip of The Week
Where Do Rats Live During The Summer?
Rodents have been able to colonize most of the earth's habitats. Different species of mice and rats are found from warm deserts to tropical mountains. Polar zones are considered the only place without rodents.
During summer, their survival instinct takes rats to shelter in place in which food is abundant and easy to get. The favorite places for rats are country houses and barns that provide them plenty of food. On the other hand, in the cities, most of the rats live in sewers where they feed on fruit, meat, and bread residues that are discarded in the garbage.
The Urban Plague
Rodents are big and repulsive. The two most known species are the gray rat or sewer rat, (Rattus Norvegicus), and the black rat or roof rat (Rattus Rattus). Although there are different species, they are both characterized by their lack of hygiene, as they live in filthy areas.
These creatures have the ability to acclimatize in urban environments because with the arrival of summer, they reproduce and start to invade people's homes to find food and shelter. Rats are among the animals that proliferate the most during summer since proper conditions for the pups' development are warm and dry conditions.
Inside Homes
Rodents will look for food and residues left on the floor. Also, places with plenty of holes and clutter. From a small crack in the wall to a space behind the fridge or the washing machine, these will be perfect places for a rodent to find refuge to save its food, live comfortably, and reproduce.
To prevent invasion problems, it is advisable to call a specialist in pest control. Proper rat extermination should be combined with actions such as tightly closing garbage cans, cleaning of the house, and other preventive measures.
