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
Why Using Poison Causes Dead Rats In The House
Unintended Victims:
Using poison can be quite risky as you could put your pets as well as young children at risk. If you're laying down rat poison throughout your home, it's possible that it could easily become targeted by toddlers who might be attracted to the small size and colors. Your pets could also be taking an unplanned trip to the hospital if they happen to ingest any of the rat poison as well.
It's Harmful To The Environment:
Using rat poison not only causes dead rats in the house but it's also harmful to the environment. You could end up with a predator in your home that's scavenging off of the dead rats, it could kill off some of the plant life in your area and it can lead to the chance that you might end up with other animals falling victim to the rat poison as well. Many homeowners have woken up to find a bobcat, fox, or coyote killed in their backyard from ingesting a rat that ate poison or from ingesting the poison themselves.
It Also Doesn't Solve The Problem:
Rats are finicky creatures and you might end up with just a few of them dead in the house before they communicate with one another and begin to avoid the areas where you place down poison and traps. Rather than facing ongoing difficulty with poisons and not getting all of the rats out of your home, choosing a different method could be a wise choice for making improvements for the future.
It's Often Time-consuming:
You might end up having to change out the poison or change your trap location on a regular basis just to capture a few rats. This can often be more time-consuming for you and your family.
