Rat in the toliet
When it comes to our Number 1 pest that slot is definitely the place given to the rat; we have a lot of issues with rats in Marlow and some areas we'll find that they come up through the drainage system of the property. Our latest job involved a dodgy builder, an uncapped outlet and nearly eight years of rats in the house. 
When it comes to providing effective rodent control in Marlow we don't come out and lay down rodenticide as our only course of action, in fact with us its the last thing that we want to do and the reason for that is simple. 
Our approach to controlling rats will always be coming from the end back to the front, does that make sense? Probably not, so OK if you have rats inside your home or your place of work the question that you'll be asking is "How do the rats get inside"? 
 
The answer to that is the end of the infestation - once we've determined that its a simple case of coming up with a plan to seal up their opening, trap out what remains and maybe, and only then do we want to consider the use of rodenticide. 
 
Using rodenticide is quick and it will deliver proven results - we'll kill the rats and that's guaranteed, however it does not get to the root of the problem. 
 
These pictures come from a house in Marlow; the owners had rented it out for years and different tenants had reported the presence of rats which had been dealt with by various pest control companies with poison. 
 
The owners had returned to the UK and were back living in the house (with the rats) and over the Christmas period one gnawed through the electric cable feeding the boiler, yet another pest control company had been called out with the inevitable result that poison had been applied. 
 
We now had a dead rat somewhere in the loft stinking the place out and we still had activity within the house; scratching noises in the downstairs toilet, sounds of movement in the cavity walls and gnawing from the loft. 
 
We were called in as the owners wanted a different approach: all our treatments start with a detailed survey and we looked at the adjoining property that formed 50% of the structure. Our first task was to inspect the exterior of both properties (semi-detached) and we found holes in the exterior walls on both sides; no signs of external activity but these were considered. 
 
We then lifted all the drain covers outside of both properties and discovered that one thing we did have was rats in the drains. Having rats living in the drains is extremely common and probably accounts for around 70% of our internal infestations. To combat this we will use CCTV cameras to survey the drains looking for faults or redundant branches that may lead off under the floor of the house. 
 
On our second visit we had trapped a rat in the loft and we could see from the coloured tracking dust that it had indeed entered our customers property via the drains. As we were getting cable damage and because we seemed to have a high proportion of rat noises we decided to poison the drains; we balance the need for using poison we prevention of further damage. Many modern houses are fitted with plastic water pipes and these will be pressurised; rats gnawing through these will mean some serious damages. 
 
Two visits and we know that the rats are coming in via the drains, that's definite and we now have poison going into the drains as an added control measure to the traps set inside the house. We looked at the flexi-connectors first; again modern construction methods use soft plastic where we used to use harder, solid plastic which rats couldn't gnaw their way through. 
 
There were three toilets in the house and two were damaged, we follow the trails that rats leave behind and two toilets had activity within but didn't have the potential to be the access point; they were damaged but not enough to allow rats inside. All this did was confirm that the drains were the route into the interior, we then used waterproof cement to seal up the holes we found in the exterior walls. For us its all about elimination of possible routes in and out for the rats. 
 
On our third visit we caught another rat in a trap and we carried out the drain survey; we do not charge anymore for the surveys, its about getting the result that we want and a greater understanding of the history of the infestation. The drain survey revealed a redundant section of pipework which although was inaccessible due to scale build up showed us that at sometime the waste water routes had been changed. 
 
We then looked at the downstairs toilet and decided that the way forward was to uncouple the toilet pan and cut into the boxing that hid the cistern; the result of this was immediate. The property had been converted and a en-suite added to the master bedroom meaning a new vertical waste pipe had been installed. The downstairs toilet had been renovated and rather than use the original waste outlet the builder branched into the new stack pipe - leaving the outlet partially open as he had placed a floor tile over most of the opening.

Eight years of sporadic rat infestation all because a lazy builder didn't bother to cap of the redundant outlet - we sealed this with a £5 metal bung, we see this all the time and this is why, rodenticide has the first or only means of control DOES NOT WORK. 
 
If you have rats inside your property in Marlow and you need a professional response then give us a call - our customers are our priority and we actually mean that. We don't hike up charges for 'CCTV drain surveys' - its a piece of equipment that we use just like our other cameras and drills, we look at your property from inside and out determined to find the rats access point.
