NEVER HAVE YOUR TRAPS SET IN THE DAYTIME.

Handle them as little as possible.  Always catch as many Rats as you can in your buildings in January and February, as they begin to breed in March, and every bitch Rat means, on the average, eight more.  Also get as much ferreting done as possible before breeding time, for a young Rat can get into the ends of the joisting under a floor, where a ferret cannot get near it, and the consequence is that a ferret is unable to cope with its task.  The best thing I can advise for clearing young Rats is a good cat, one that must not be handled nor made a pet of, but allowed to live in almost a wild state.  A good cat can do as much, in my opinion, in one night, when Rats are breeding, as two ferrets can do in a day, especially in a building where there are cavity walls, as it is impossible for a ferret to follow a Rat in such walls.

This is all the information I am able to give on the trapping of Rats—­a method I have proved by 25 years’ experience to excel all others.  Still another way of clearing the pests is as follows:—­The majority of Rats are Black, or what we call Drain Rats; if they are in a building they will in most cases come from a water-closet.  Sometimes you will see from the drain pipes in the water-closet, say, a six-inch pipe fitted into a nine-inch pipe, and the joint covered round with clay, through which the Rats eat and scratch and get into the building in great numbers in the night, but most of them return into the drains during the day.  Now, if it is the breeding season (about eight months out of the twelve) they will do much damage to silk, cotton, leather, lace, and, in fact, all other light goods.  And one would be surprised to see the quantity of cloth, paper, etc., they will procure for their nests whilst breeding.

The way to get clear of these is to go in the day with two or three ferrets and leave the drain pipe open.  Ferret them all back into the drain; don’t put a net over the drain for fear you might miss one or two.  If they got back into the building they would be hard to catch, as they would not face the net again.  Then, after ferreting, make the drain good, and if there be an odd Rat or two left in the building you will get them in a few nights by baiting the trap.

There is another way of catching the Brown Rat which breeds under the floor in large buildings where there are no drains.  They are very awkward to catch.  Always have a trap or two set, but do not set them where they feed; place them in their runs.  But there are other methods for other Rat-infested places.  For instance, take a restaurant, where they feed in the cooking kitchen; we will suppose they have eaten four holes through either floor or skirting boards.  The best way to catch these—­however many holes they have leading into the kitchen—­is to block up (with tin or similar material) all the
