A rat infestation is a serious issue for any homeowner. Left to their own devices, rats will multiply and cause severe damage to property and possessions. Rat infestations must be dealt with as soon as they are identified. Fortunately, while rats are good at sneaking into properties unnoticed and establishing their nests, they aren’t so good at keeping their presence a secret. As soon as rats enter your property, they will begin leaving evidence that can alert you to their presence. If you know what to look for, that is.
Other than seeing a rat in your home with your own eyes, the next most surefire sign of a rat problem is their droppings. Rat droppings are much larger than mouse droppings, around the size of a currant. If mice are scurrying around your home and leaving their droppings around the place, you will almost certainly be able to hear them. Although rats are good at accessing seemingly-inaccessible spaces, they aren’t the quietest of animals. As well as the sound of their feet scratching against your walls and ceilings, you will also often hear the telltale sound of rats gnawing. Rats gnaw more frequently than mice, and their larger teeth generate more noise. They also leave behind teeth marks that are far too big to have come from a mouse.
One of the less well-known signs of a rat infestation is rub marks. Rats are dirty creatures, and their bodies are usually covered in grease and dirt. When rats squeeze through narrow gaps, they will often leave dark smudges on the surfaces they brush against. The more often they come into contact with a surface, the more obvious the rub marks will be.
Some of the signs of a rat problem overlap with mice. Knowing which pest you’re dealing with is crucial for getting rid of them in the right way. If you’re unsure which pest you’re dealing with, contact a professional pest control contractor.
