Rodent Infestation

Rodent Infestation

Normally on this website, we talk exclusively about insect infestations. But, I feel like it’s time to broaden our horizons and teach people about other kinds. That’s why today we’ll be going over a possible Rodent Infestation. We’ll talk about rats specifically, and how you can notice if they’re in your home.

Rodent Infestation: The Signs

Rats are nocturnal animals, so you’ll almost never just see them out in your home. They’ll leave signs around, though, and these are what you need to look for.

• Rat Droppings – usually found in concentrated areas as rats produce up to 40 droppings per night. Brown rat droppings are dark brown in a tapered, spindle shape about 9mm – 14mm long. They can resemble a large grain of rice.
• Scratching Noises – Think you might have rats in your roof? Black rats (also known as the roof rat) are agile climbers and can easily gain access into loft spaces and upper floors of buildings. Hearing scratching noises at night from above may suggest their presence. Brown rats, on the other hand, are less adept climbers. You may hear them scurrying under decking, sheds, and floorboards. They are more likely to be identified by a grinding noise they make with their teeth known as bruxing.
• Footprints (running tracks) – Rats leave foot and tail marks in dusty, less-used areas of buildings. Shining a strong flashlight at a low angle should reveal tracks clearly. To establish if an infestation is active, sprinkle fine flour or talc along a small stretch of floor near the footprints and check for fresh tracks the next day.
• Rub Marks – Rats use established routes along baseboards and walls due to their poor eyesight. Grease and dirt on their bodies leave smudges and dark marks on both objects and surfaces they repeatedly brush against. These marks may indicate rodent activity, but as smears may remain for a long period of time, they are not a good gauge of an active infestation.
• Damage – Rats have teeth that grow continuously. They need to gnaw on wood and plastic to keep them trim. They have the potential to cause fires by chewing through electrical cables. You may also notice ripped food packaging, as rats tear open food, leaving visible teeth marks.
• Nests – Rats build nests in warm, hidden places using shredded material such as newspaper and fabrics. Nests will often contain young rats and are usually located close to a food source. Check behind and under appliances, such as fridges and freezers in or near your kitchen.
• Burrows – Some rats are well known for digging and excavating extensive burrow systems for shelter, food storage, and nesting. Look for burrows in compost heaps, under decking or garden sheds, or in garages.

These are all telltale examples of a possible rodent infestation, and you should call a professional if you find these.
