The field over the garden fence is like paradise for rats! |
There's a train of thought that you're never further than about 20 feet away from a rat wherever you are in the UK.
Certainly a rat will have been within 20 feet of where you are now at some time or another.
It was probably around November last year when I noticed the first signs that some unwanted furry creatures had taken up residence in the garden. Living in the countryside I wasn't overly concerned that I'd caught a fleeting glimpse of a rat one day, but a couple of weeks later - when I saw three of them sat brazenly underneath the chicken loft in broad daylight - I knew it was definitely time to act. If I'd seen three of them together, the chances are that there were many more out of sight.
I should probably say at this stage that prevention is far better than cure. If you remove sources of food, shelter and water from your garden then it is far less likely that rats will take up residence. For that reason it is crucially important that chicken feed is removed every night, spillages are cleaned up and the run is kept in a generally clean and tidy condition.
Controlling Rodents
Having established there was a problem, I quickly got to work researching different ways of controlling our resident rodent population. There were three main options:
- Get a small dog or cat: Small dogs, terriers in particular, will sniff out rat nests and destroy the contents. They latch onto rats with their teeth and effectively shake them to death. Outdoor cats will also have a go at rats, but not as effectively as a terrier. Cats are pretty good for dealing with mice. Unfortunately we don't have a dog or cat and I wasn't going to get one just for the purpose of killing rats.
- Trapping: This involves placing baited traps at strategic points where rat activity has been seen or suspected. The traps need to be somehow protected so that they are not accidentally sprung by other animals. You can get lethal snap traps and non-lethal cage-type traps, which allow you to release the rat elsewhere or otherwise dispatch it. Rats are clever animals and suspicious of anything new in their surroundings. For that reason it might take a few days before they are bold enough to spring the trap.
- Poisoning: This involves placing poison at strategic points where rat activity has been seen or suspected. In common with traps, it will take a few days for the rats to become bold enough to take the bait. Once they've started eating they will return for more and quickly consume a fatal dose. It might take a few days for the poison to act.
Having weighed up the options, I decided that a combination of trapping and poisoning would work most effectively. Speaking to fellow chicken keepers, I think most of them do likewise.
Trapping
I bought half a dozen
Victor Easy Set rat traps from Amazon. You should always wear gloves when handling rat traps, so that your scent doesn't get onto them and no nasty microbes get onto your hands.

I baited the traps with a tiny amount of peanut butter and placed them underneath the chicken loft and beside the shed without setting them. They were left out for a few days for the rats to get used to them. When it was time to use the "live" traps I put the chickens away in their loft for the night and set the traps. The following morning I had a dead rat in each trap. I disposed of the bodies in the incinerator, but it is acceptable to bury them or wrap them in plastic bags and put them in the normal rubbish bin.
I repeated the cycle every evening and slowly but surely the number of rats caught in the traps went down. There are still a few traps in the garden just in case, but I have not caught anything for months.

Poison
In addition to the rat traps I bought four
double bait stations and
3 kg of Pest Expert Formula B rat poison. Again, you should always wear gloves when handling the bait stations or poison. The poison should be stored securely somewhere cool and dry. For safety reasons, it should never be used uncovered. The enclosed design of the bait station protects the poison from non-target animals and children. Even so, it is a good idea to position them where they won't be disturbed by anything apart from rats.

I filled the bait stations with poison and used a permanent marker pen to mark the level of poison in each of them. I them placed them in likely "rat runs" along the garden fence and beside the shed. It took a few days for the level of poison to go down, but once the rats had found the taste for it they ate a lot. Every few days I would walk around and check the bait stations and refill them as necessary.
I also took a few of the small poison throw bags and pushed them underneath the shed with a broom shank.

After a month or so, it was apparent that bait was being taken from only one of the bait stations, which was right next to a hole underneath the garden fence. From this observation I concluded that there were no more rats living in the garden and bait was only being taken by a few visiting rats from the adjacent field. That remains the situation today, but I can live with that. Living in the countryside it is unrealistic to expect to get rid of rats entirely.

I should probably mention that it is a good idea to change the brand of rat poison that you use on a regular basis. This helps to prevent the rats developing immunity to any particular brand.
I have never found the body of a poisoned rat, because they all head back into the nearby field to die a few days after taking the poison. If you do find the body of a rat then it must be disposed of properly (e.g. buried, burnt or bagged, as described earlier). If the body was left in the open another animal might come along and eat it, thus being exposed to the poison.
