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
Are Rats Able to Dream?
Talking about rats implies talking about pests. But let's not forget that these curious animals have been used in various scientific studies regarding sleep. In this post, we want to give you a brief description of what has been discovered about rats and sleep.
Do rats sleep?
If you ever have had the chance to see any of these little rodents, you should know that:- They are nocturnal animals
- They do not have the same sleep phases as humans
- They cannot see in color; they are colorblind
- These animals have many interesting characteristics, but the most interesting of them all is they incorporate the REM phase in their sleep
What is the REM cycle?
It is the phase of sleep in which our sleep becomes heavier. The brain waves that predominate behave the way they do when we are awake; this makes our heart rate and pressure increase, as well as the movement of our eyes (Rapid Eye Movement). There is no muscle tone and it is the moment we have dreams. Rats also experience the REM cycle.
So... do rats dream?
We could say yes; studies have shown that these medium-sized rodents incorporate this stage in their sleep phases. It's also important for you to know that their cycles are shorter and more widely spaced throughout the day.
That's why they will probably only see images, due to the absence of reasoning, they could not put together a story in their dreams.
Why they go out at night
It is difficult for a rat to cross your path during the day, and they have the need to go out and look for food. You will rarely see them wandering around during the day, as they tend to hide and sleep. But when night falls, they take advantage of the stillness and silence to seek supplies and prowl around.
