Rats in cavity wall


Postby Bris » Fri May 27, 2011 10:09 am

I have also had terrible problems with rats in my cavity wall and kitchen ceiling. It doesn't matter whst I do they always seem to come back. My house is a typical victorian mid terraced property. There is an extension at the back which is the kitchen and one bedroom built above it. This part is built over the old drain and also the new one. This seems to be the root of the problem, however they have blocked off the old drain and although the activity seemd to stop for a while they found their way back in again after a while. I've spent thousands of pounds trying to sort this out and really don't know what to do. Ive had different pest control companies in, drainage experts in, builders in, even had a guy in yesterday who put down a chilli gel which is supposed to repel them. I had my doubts about this but he told me he had treated 600 houses with it and no one had complained. Anyway last night I woke to hear a rat scratching around in a section where he and put this gel so am now very dubious about it. Poison seems to be a bit futile because as one dies another one enters. I have also had dead rats decomposing in my ceiling and it isn;t pleasant. I have lived in this house for 5 years and from what the neighbours tell me the previous owner also tried and failed to deal with the rats. I am at a loss as what to really. Any ideas would be gratefully received.

Simply Build It

[quote="avr"]We have the exact same problem and would love to know whether you resolved the problem via drains - is it over for you yet? The extension was built before our purchase of the property 6 years ago. However, it has only been a problem for the past 9 months within the house and has continued to worsen with rats now gaining access to other ceiling areas in the house. Pest control conducted a drain survey but weren't convinced that their equipment would pick up the fault - they are convinced it is from the drains. They have laid poison numerous times. We are getting pretty desperate.
Look forward to any latest news from you.[/quote]

Firstly I hope your situation has improved? I realise what a stressful time it is. Solving the drain problem in our kitchen was without doubt the best thing. A complete new drain cover was put in place. Years ago extentions were built without planning were'nt they? The original builder hadnt sealed the drain off properly ( i would love to spend a couple of hrs with him!) This did solve the problem but since we have had a couple more rats get in. My husband has since sealed the cavities from the loft and we did find a hole in the loft that led to next dr. Are you terraced? Our neighbour has since heard noises in their loft but fingers crossed we havent. Our neighbour has been in their property 2 yrs. They are the first neighbours we have had that have admitted there was a problem. They have sealed holes in their loft and brought something that gives the rats an electric shock... finially having good neighbours has helped. Its also a help to read others letters and realise we are not the only people with this problem. Poisen is not the answer because of the terrible smell. Good luck

From our experience i would also say it was your drains that is problem. Are you able to get the floor up to view the drains? I wonder if your neighbours have a problem? At the time some of the neighbours didnt want to admit there was a problem. Seal the tops of your cavities from the loft, and any holes in the loft. Im sure you have probably done all this...I realise what a horrible situation this is. good luck

As a Professional Home maintenance advisor and faced with a rat problem in the air space of a flat roof extension.I did make so many wrong assumptions (i need to go back to school) however it may help some one to know the outcome.I carried out a full detailed investigation of the structure and eaves both on this property and next door as it is a terrace approx 1820s and could not find any access way for them to get in.The final outcome was when i realised that we had employed a flat roof company some 7 years previous to re-felt the roof and by removing the vent on the soil stack found that they had cut off the top 18" of the foul pipe, re-boarded the roof and re-felted and then remembered that they needed to re-fit the top back on and guestimated the position of the lower half of the stack so that the top 18" was not in line by some 2.5" and as such the rats came up the soil stack and through the overlap.And that i now know that rats climb vertical 100mm pipes by pushing their back to one side of the pipe and strenching their legs out climb quite easily and they reverse this going down as i have watched this happen using a 9mm flexible pipe camera.The main question is who would assume that the foul pipe was not in one piece ?

ok some of you know im sueing the builder who built my house but ive a new problem now..lol
Ok monday had the council out to bait cos we had something going in and out of the cavity wall between us and next door, the council guy confirmed it was a rat ( or more then one) getting in via next doors water/sewage drain cos he found rat droppings, so he baited the main drain and a smaller on in the road and will be back in a week, thought ok rat be dead in a few days. guy next door isnt interested even though its in his walls, behind his cupboards and under his stairs, but its driving me nuts and i dont want it getting into the house or biting my power cables behind the power point where it seems to like scratching. So any ideas guys???
rep for any ideas im getting to the point i dont want to open the doors unless i have something heavy and big in my hand..lol cant bait anywhere outside the drain as i have a little boy and there are a million cats that just LOVE my garden

The first step in rat pest control is to understand your foe; simply putting down a rat killer or rat poison is unlikely to solve your problem. Rat pest control can be a very straightforward procedure as long as you fully understand the behavioural traits of the rats. We receive far too many emails from people who have used a rat killer poison only to discover that they subsequently end up with a rotting corpse under their floor boards. By reading the following we hope you will become a mini expert on rats. This section has been written for us by Ed Allen who is regarded as one of the worlds experts on rat pest control.

Hi there, I have a similar problem with rats getting into the loft of my extensions and would like to read the article mentioned in the previous post, should there be a link?

Cheers!
