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
What Diseases Are Caused By Rat Urine?
Rats are undoubtedly one of the animals that transmit the greatest number of diseases worldwide. These rodents are a very unpleasant species for humans, not only because they spend a lot of time in the garbage, but also because of the risk they pose to humans.
How Can You Get Infected Through A Rat's Urine?
Unfortunately, there are many ways a person can get a disease, virus, or infection from a rodent. From the moment a rat enters your property, you are exposed to a number of dangers that can seriously affect your health.
It is possible to become infected through direct contact with an object or food contaminated with rat urine. Rats often leave a trail of urine so that other rats can follow it to the best food source. This is why there could be rat urine on your food or even in the water.
Another way to get infected is to inhale dust contaminated with rat urine. The most frequent way to get infected by rat urine is through a fresh wound; the infection will have better access to your body.
Hantavirus
It is considered to be a viral disease that seriously affects the body; it can cause hemorrhagic fever and affect the lungs. The disease is found in rodents of all types and is mainly transmitted through their urine. Some symptoms of the disease are:- Fever
- Muscular aches and chills
- Dizziness
- Gastrointestinal problems
Leptospirosis
This infection may be better known as Weil's disease. It is considered to be a risky illness because if it is not treated in time it could be fatal. It is transmitted to humans through the urine of a carrier animal, including rats. This infection has all the symptoms of a normal infection, such as fever, dizziness, and body pain, except this infection can affect multiple important organs.
