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
Is It Common For Rats To Bite Humans While They're Sleeping?
There have been many cases reported in which human beings have been bitten by rodents. People tend to be alarmed when seeing a rat, not just for being repulsive but for the notoriety they have. However, some rumors are just myths that are a bit exaggerated.
Any animal tends to behave aggressively if they feel threatened or in a dangerous situation. In the case of rodents, the behavior is the same. Most of the times they want to go unnoticed, but if they feel cornered they can bite in defense to escape.
Can Rats Bite People While They're Asleep?
It is a rare thing that a rat climbs to someone's bed and bites them. Generally, the occasions in which a rodent climbs a piece of furniture has to do with dirtiness. A messy bed with crumbs of food will attract a rodent.
In these situations, the animal does not normally attack the person. However, some rats sometimes bite kids when they sleep. These exceptions happen because these kids are in low hygiene conditions with crumbs of food on their hands and the smell of this food is an open invitation for rats and their instinct for feeding.
Rats And Infections
People that have been bitten by a rat usually say it is a very strong pain. It is known that their teeth can deeply penetrate the skin, whereby it is necessary to act and clean the wound quickly to prevent the spread of diseases that can be caused when their saliva enters in contact with the bloodstream.
Rodents are vectors in the transmission of many diseases due to the bacteria and viruses they carry. A messy and dirty house is sought after by rodents, due to the abundance of areas suitable for nests. For this reason, if you wish to prevent a rodent infestation, you should keep your house clean.
