Signs of a Rat Infestation in Your Home

Your Home could possibly be a home to rats too if you are constantly hearing scratching noises under the floor boards, in the structure, or have spotted dark brown droppings (about the size of a coffee bean) in the kitchen or in areas of the house. Rats are not just troublesome creatures that eat your food or can cause damage to your property; they are carriers of diseases too such as Weils, Rat bite fever and Cryptosporidiosis. Rats also carry parasites such as lice, flea and ticks. They are very intelligent and cannot just be treated by using DIY methods to try and eradicate them from your home.

If you recently experienced any of this, you need to call Mercury Pest Control London. We will provide specialist treatments for all levels of infestations in Domestic and Commercial Pest control.

Signs That Tell You Have a Potential Rat Problem

If you thought rats are as brazen as mice and you can easily see them go about their work, you are partially wrong. Rats are mainly active during the night due to being nocturnal.  Hence spotting a Rat during the daytime is usually a difficult task. Yes, mice are also nocturnal, but Rats suffer from neophobia which means they have an extreme dislike and irrational fear of something new. This is why many Rat issues can go undetected for long periods of time and before you know it that one or two Rats has turned into one or two litters. Here are some of the most common signs of a Rat infestation:

Drainage issues

Majority of Rat infestations are usually drain related. This can be caused by damaged old Victorian pipe work or a blockage in your system which Rats find easy to breach as they can simply swim through your pipework. If you are having pungent smells of sewage or had a recent drainage issue then this can also be a sign that you might be having a problem.

Scratching Noises

Rats can climb just about anywhere when they go in search of food. You may often hear scratching noises in the night from places such as under the floorboards or kitchen units, the attic and in storage cabinets. Rats often gnaw on wood, plastic and even concrete as they need to sharpen down their teeth or they will die. This is due to their lower incisors which don’t stop growing and would drill through the roof of its mouth and therefore cause the inevitable. The other reason you may also hear scratching noises at night can be due to them trying to gather nesting materials for a new harbourage location.

Smearing Marks

Will usually occur around pipework, on top of kickboards, especially under the dishwasher due to the gap made for leverage for it to open, bin cupboards, food shelving units, corners of rooms and other potential runs they may have. These can all result in visible smearing marks appearing from the grease and dirt on the bodies of Rats. They will also go scurrying from one place to another and in doing so Rats leave a trail that can often become quite smelly and stubborn to remove if left unattended. This is why we highly recommend that the infestation is dealt with a quickly as possible, as when left these smells may stay around for a long period of time after the infestation has been fully eradicated.


Rats can leave foot and tail marks in less-used and dusty areas of the home or building. Under kitchen units, storage rooms, boiler cupboards, bin areas, attics and unused areas under stairs are all possible places where you can easily find rat footprints.

Rat Droppings

Rat droppings are one of the most important signs that tell you that you need to immediately hire a domestic Rat extermination company in London. Rat droppings are brown in colour and spindle-shaped like a coffee bean. Do not ignore any sightings of rat droppings, especially in you have noticed them inside your house hold. Rats multiply fast and an increase in Rat droppings is a sure-shot sign that you have a rodent problem to deal with.

Rat Burrows and Nests

Another common sign of a rat infestation is the presence of rat runs, burrows and nests in your property these areas can include; lofts, under floorboards, plant rooms, under kitchen units, storage cupboards and bin cupboards. They may also be discovered in the external part of your property such as under sheds, flower beds and under decking areas which are again ideal harbourage locations for them to nest. Decking has always been an ideal location for them, due to it being a safe place away from potential predators like, foxes and being in a much closer proximity able to breach your property.
