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
Can A Rat Have Rabies?
Rats have powerful bites:
Rats can have very powerful bites and are capable of damaging the skin quickly. A rat can bite through cinderblocks to get into an area if it needs to. Rats could bite through clothing or manage to break the skin even unintentionally with a very quick bite. Handling rats with care or using heavy gloves is recommended if you have to remove one or relocate it. It is ultimately best if you avoid handling rats whenever possible.
Many people are bitten each year with low rates of infection:
Rats bite over 50,000 people in the USA each year. Rabies vaccine shots are very rarely delivered in these cases and the risk for other types of diseases that rats carry can be far greater. Going to see a doctor about a rat bite can be wise if you are starting to feel some of the secondary symptoms or it looks infected.
Rats do spread disease:
Rats do spread a series of diseases including rat-bite fever. It can be transmitted through a bite or through pets. Rabies can be a deadly disease but most of the diseases that rats pass on are only able to cause the chance for fever and infection which carry lower rates of mortality.
Other animals can be much riskier to receive bites from:
If you are bitten by other animals like raccoons, coyotes, woodchucks, or skunks, this will give you a much riskier chance of receiving something like rabies. When bitten by a rat, you should be concerned but you may not have to run to get the bite checked out with the same urgency.
The main theory of low rabies cases:
A rat would have to survive a bite from a predator in order to become a carrier of rabies. As coyotes and larger animals will be likely to kill a rat in an attack, this leads to the chance of rats not being able to spread rabies at all.
