Pest control solutions for rats and mice

Pest control solutions for rats and mice should include identifying potential food sources, such as pet food and garbage cans, and sealing off any potential entryways in the house. Cleaning up rat and mice droppings can be hazardous, as they can carry a variety of diseases, such as hemorrhagic fever, so it is important to wear rubber gloves and a mask when cleaning up rodent droppings. Rat urine can also carry health risks, so it is important to thoroughly clean any areas where rats have been present.

Black rats are the most common type of rat found in urban areas, and they tend to be larger than other types of rats, such as Norway rats. As such, their droppings can be larger than other types of rodent droppings. To control and prevent rats and mice from entering the home, it is important to invest in effective rodent control methods, such as traps, baits, and exclusion devices.

How to prevent rat and mouse infestations

Finally, it is important to note that black rats tend to be larger than other types of rats, so their droppings can be larger than other types of rodent droppings.

The Hidden Dangers of Rat Faeces and How to Protect Yourself

Rat faeces can be a health hazard, as they can contain harmful bacteria and viruses that can cause serious illnesses. It is important to take steps to protect yourself from coming into contact with rat faeces.

Rat faeces can be dangerous as they may contain parasites and bacteria that can cause serious illnesses in humans. These parasites and bacteria can be transferred through contact with rat faeces, and can be ingested if not properly handled. Some of the illnesses associated with rat faeces include such as rat-bite fever, toxoplasmosis, and lymphocytic choriomeningitis virus (LCMV). salmonella, leptospirosis, and hantavirus. 


To protect yourself from the hidden dangers of rat faeces, you should:


  1. Seal any cracks or openings in your home to prevent rats from entering.


  1. Clean up any rat droppings as soon as you spot them, using a damp cloth and wearing protective gloves.


  1. Use traps to capture and remove rats from your home.


  1. Dispose of rat droppings in a sealed bag.


  1. Vacuum your home regularly to remove any droppings or debris.


  1. Wear protective gear such as gloves and masks when cleaning up rat droppings.


  1. Wash your hands after coming into contact with rat droppings.


  1. Avoid contact with wild rats or their droppings.


By taking these steps, you can help protect yourself from the hidden dangers of rat faeces.


Are rat droppings dangerous for dogs? 


.Yes, rat droppings can be dangerous to dogs, as they can contain a variety of parasites, bacteria, and viruses. Rat droppings can carry disease-causing organisms such as Salmonella and Leptospira, which can lead to serious illness or even death in dogs. 


Additionally, rat droppings can carry mites and fleas that can cause skin and ear infections in dogs. To keep your dog safe, it is important to clean up rat droppings in your home as soon as possible, and to take your dog to the vet for regular check-ups.


Are rat faeces dangerous to clean by a pregnant woman?

If a pregnant woman must clean up rat faeces, it is important to take certain precautions. These include wearing protective clothing such as gloves, a face mask, and long sleeve shirt and pants, and cleaning the area thoroughly with a disinfectant. It is also important to ensure that any waste material is disposed of safely, preferably by a professional pest control service.

What’s the Difference Between Rat Droppings And Squirrel Poop? 


Rat droppings and squirrel poop are both dark, often either black or dark brown in colour. Rat droppings are usually pointed at both ends, whereas squirrel droppings are more elongated and curved.


In terms of size, rat droppings are usually about 4 to 8 millimetres long, while squirrel droppings are about 10 to 14 millimetres.


Rat droppings are usually found in clusters, as rats tend to defecate in the same areas. Squirrels, on the other hand, tend to defecate more singly.


Rat droppings are also distinguished by their smell, which is quite strong and pungent. Squirrel droppings, on the other hand, tend to be much less pungent.


Finally, rat droppings often contain undigested food, such as seeds and grains, while squirrel droppings typically do not.


How to Safely Clean Rat Droppings?

  1. Wear protective clothing: Before you start cleaning up rat droppings, make sure you are wearing protective clothing. This includes a coverall, gloves, goggles, and a face mask.


  1. Clean up the droppings: Use a vacuum cleaner to suck up the droppings and then dispose of the bag in an outdoor trash can. If you are using a broom and dustpan, be sure to wear a face mask and gloves.


  1. Disinfect the area: Once you have cleaned up the droppings, you should disinfect the area with a household cleaner or bleach solution. Be sure to follow the directions on the label.


  1. Remove any odours: If the area still smells of rat droppings, use an enzymatic pet odour remover or an odour-eliminating product specifically designed to remove odours from rodent droppings.


  1. Clean up any food sources: If the rat droppings are near a food source (such as a kitchen), make sure to remove and clean up any food that may have been contaminated.


  1. Seal off any entry points: To prevent the rats from coming back, make sure to seal off any entry points into your home, such as cracks in the walls or holes in the foundation.


Size of rat dropping

One of the first indications most people have that they have a rodent infestation in their home is the appearance of droppings. You are more likely to see the droppings than the rodents themselves, at least during the early stages of an infestation.

Rodents will do everything they can to stay hidden and out of sight, only emerging when they need to scavenge for food or materials for their nests. But they can’t help but leave their droppings wherever they go.

Knowing the difference between mouse droppings and rat droppings will enable you to work out which one is responsible should you find any in your home. They share a few similarities, but for the most part, it’s easy to tell rat droppings apart from mouse droppings. 

The most significant difference between them is the size; rat droppings are larger than mouse droppings. The exact size and shape of a rat’s droppings will depend on its species, but they are all quite similar in nature. 

All rat species leave pellet-shaped droppings that are about 3/4 inches long and 1/4 inches thick. They usually look like mouse droppings, only larger. Unlike mouse poop, which is generally found in clusters, rat droppings are usually found in isolation. This is because, unlike mice, rats defecate while on the move.

It’s also important to appreciate the danger rat droppings pose. Rat droppings can cause severe illness in humans if even tiny amounts are ingested. Other than contaminating food and drink, microscopic particles of rat poop can end up inside people if they try to clean it up without proper precautions. 

As the droppings dry out, they become prone to disintegrating into dust. People can easily inhale this dust if it’s disturbed during the cleaning process; you must wear gloves and cover your face whenever you’re cleaning up rat droppings.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.
