Rat nesting habits and life cycles are very similar to that of mice. They can cause huge challenges for both domestic and commercial premises. As a result of this disease can spread to humans with relative ease if left untreated and infestations are allowed to grow. The most well known disease carried by rats is Weil’s disease. However, they can also contaminate food and water which can lead to salmonella poisoning. Risk of damage is also extremely high with rats, due to their incisors (teeth) constantly growing resulting in them needing to constantly gnaw. This can cause serious issues to the infrastructure of both residential and commercial properties.

  • Rats breed at a rapid rate and become sexually mature within 3 months of birth.
  • Each female rat may produce between 3-12 litters of 6-8 young each year. Issues can easily get out of hand!
  • Naturally rats can live from between 6 months to a year.


  • Rats – Even though rats are predominantly nocturnal animals, they have been known to venture out during the day and most people realise they have a rat issue after seeing the pest.
    Damage to food produce – Rats will eat almost anything they come across so look out for any unexplained nibbling on food. Also, this can lead to a very high risk of cross contamination, damage to wires and piping.
  • Droppings – This is sometimes the easiest way to spot a rat intruder! Their droppings tend to be black in appearance and are roughly the size of a small fingernail.
  • Smear marks – Due to the dirty environment that rats live in their fur tends to be dirty and greasy. As they run along certain areas repeatedly a black mark can build up on the surface. This is known as a smear mark.


  • Our highly trained technicians will first establish where the infestation is coming from. In many cases rats gain access to a premises via the space around piping, loose or broken air bricks or spaces around the wiring. An adult rat requires a space no bigger than a fist to enter a premises, and in some cases will exploit holes to gain entry.
  • Once ingress points have been established, a course of treatment will be undertaken with the use of specialist rodenticide baits, with the aim to reduce the current population of the infestation.
  • When your technician is happy that the infestation has ceased, the client will be informed of ways in which to prevent reoccurring infestations. If you would like to know how QuicKil can help you with specialist prevention methods please see our prevention page.
