I use a bait containing Bromadiolone, actually have been using it for a
number of years and have no issues with it. I like Bell Labs product
called Contrac, mainly because their baits are made with the rat taste
in mind. There are other baits containing Bromadiolone, but if the rats
don't eat it it won't kill them.
At the moment I can't think of a reference for you...a friends site has
some general information, but it also has some info we differ on.
Most of what a professional learns, other than the generic "classroom"
type knowledge of "this is a rat 101" comes from being out in the field
and constantly being amazed what rats do to survive amongst us.
This is a juvenile rattus rattus I caught the other day.
This is a roof rat, tree rat, fruit rat or "palmetto squirrel" for the
chamber of commerce folks. They get about 50% bigger full grown.
Our readers should note the identifying long tail. The mesh is 1/2"
hardware screen and these guys can eat a hole through it (I have a
patch in this trap). Peanut butter with dog food in it did the trick
on this one. He now sleeps with the fishes. "Cute" didn't save his
Seriously though - seems like I have roof rats. We hear them scurrying
around at night.
If antifreeze is so effective, AND, I have no animals that might get to
it, seems like that would be best.
My problem is that if they go back into the roof/rafters, I am
concerned about disease as they die up there.
I don't like the idea of traps since the doggone animals are awfully
smart - had a bid for an exterminator and it was WAY too expensive.
I liked the 5 gallon bucket idea, but I wasn't clear on how to get them
to go into it willingly. I don't have oats, so need another temptation
for them, plus, how to rig the bucket???

The 5 gal bucket trick is to fill it 3/4 up with water. Place a layer of
bird seed (oats) on the water..make a ramp with a board with a light
trail of the bird seed up the board...rodent works itself up the ramp
then drops down on to the birdseed in the bucket thinking it is solid
Better make sure that is a new shiny bucket. If there is any texture
on it at all they will just climb out. I am amazed at what the roof
rat can climb, I also had one eat a hole in a 30 gallon rubbermaid
trash can before I could get my pistol to shoot the little bastard I
had the top on it because one had jumped out already. (why I know the
three foot jump thing)
Rattus rattus is a very common pest here is SW Florida. They eat
pretty much everything people plant in their yards and a palm tree is
a rat condo. Of course an attic is the Taj Mahal. Once they eat a few
holes in the A/C ducts it is air conditioned up there.
All cats do is kill everything else that is eating the food on the
ground like birds, rabbits and squirrels so the only thing there to
eat it is the rats and a cat can't eat as fast as a rat can fuck.
Rats can also go places a cat can't. A roof rat could live his whole
life without ever touching the ground.
You show me a neighborhood overrun by cats and I will show you one
with a roof rat problem.
If you really want to control rats natutrally you want black racers or
rat snakes. They have no problem climbing trees and going into the
holes where rats live, eating all the babies. They will also take on
an adult if it shows up.
Cats will kill them too.
Rats are like any other uninvited guest. When you stop feeding
them, they will leave.
Actually, that's only half the story. When you remove their food,
they are still instinctually bound to stay where they are as much
as they can, and they will eat their young as a food source rather
than go elsewhere. Because they are generally destined to die
unless they can find another site where they won't be 'trespassing'.
In my experience, the presence of dogs, their food, and their feces
are an extremely common theme with rat infestations.

Here is the surest solution.
Load all the rats up on a bus and take it to New Jersey.
Once there the Rats will definately run for office.
They will undoubtedly all win....and stay.
The majority of the rats I deal with in the Dallas area are roof
rats..the common theme I have seen is vertical growing vines. Jasmine,
honeysuckle, English ivy. As many rat calls that I can remember either
on the property or the adjacent ones will be found the vines allowed to
grow upwards on the fence, trees, arbors, even when just on the ground
thick up against the house a rat nest usually can be found.
Ya know, White Castles are very popular around here.
Don't know why, since they have a Communion-wafer
sized patty, and the burgers are 2-for-a-dollar.
But anyway, they are open 24/7. So if I were to arrive
at one, to find it closed, I'd not wait in their parking lot
for them to open, I'd go elsewhere.
Same thing for rats. If they don't find food, they'll go
elsewhere. Regardless of where or how their nests
are located or accessed, they will try to be near to their
I hope that by now everybody here understands that rats
eat dog feces. For undigested food, and for vitamin B-6
that they don't absorb well on the 'first pass'.
So I say again, if there are rats, eliminate their food sources.
And be especially watching for dogs and their associated
food sources of whatever variety.
I was most interested by your ace in the hole. Antifreeze. I would
be interested if anyone has knowledge if Antifreeze would pose the
same danger to house animals as poison does. (snip)
In any mammal, including humans, ethylene glycol (the major component
of earlier generation antifreezes) will convert to oxalic acid in the
body which crystallizes in the kidneys, causing a painful internal
bleed leading to death. (A few humans have been saved from same with a
kidney transplant). The sweet odor and taste of it attracts animals and
even small children to consume it. It is one of the major causes of dog
deaths in this country. (the newer antifreezes use propylene glycol,
which is far less toxic).
The Warfarin products that some rat populations are resistant to is
believed to be due to the emergence of a digestive bacteria in the
target rats that produces large amounts of vitamin K, which counteracts
the Warfarin. I believe some newer baits have been formulated with an
antibiotic that kills this bacteria so the Warfarin can do its work. I
do not know the brand name, or where to get it.
I have used a Benjamin .22 pump air rifle with some occasional

They will start eating each other.
