When you are suspicious of rodents that have invaded your house, the first thing you need to is to figure out they are mice or rats. And then, you need to figure out their population. This is very important. Before using any methods to repel or kill them, inspect these premises completely. A thorough inspection will be so important that can determine which method will be used to get rid of these rodents. This also determines the success rate of rodent control.
How to inspect?
If you conduct a good inspection, you can know what type of rodents is in your home, what their patterns of activity are, what attracts them to invade your home and which method can effectively help you get rid of them. Therefore, a carefully prepared inspection can help you easily determine:
- The specific rodents in your home. They are rats (root rats or Norway rats) or mice.
- Their population and the severity of the invasion.
- Where the nest, move around and eat.
- What factors cause the problem of invasion? It is due to available food, water or poor sanitation?
- The best rodent control method and the best place to place traps, baits, poison, etc.
- Other factors to improve the success rate of rodent control
Because they are active at night and love to move around in hidden areas, you need a flashlight to check dark areas where they are likely to hide. A good inspection needs you to examine up, down and all around for evidence. These signs can tell you more, including:
Signs of mice and rats presence include:
- Rodent droppings – These disgusting droppings, of course, tell you that they are there. And the droppings can also tell you more, like rats or mice, the size of population, the areas where you are most likely to be active. Mouse droppings are about less than 1/4 inch long and both the ends are pointed, while rat droppings are lager – about 1/2 inch long. The dropping ends of roof rats and Norway rats are different. The roof rats’ droppings have pointed ends, while Norway rats’ are blunt. New droppings present to be putty and shiny compared with old hard and crumbly droppings. If droppings are of different sizes, this probably means adults and juveniles are living together. Plenty of droppings indicate a large infestation.
- The location of droppings probably is the most active areas. This also means they are the best places to place traps or baits. The types determine your need to place rats or mice traps/ products.
- Rodent urine – If you suffer a large infestation, you may smell the strong musky odor of their urine.
- Mice can gnaw holes and gnawed holes are small and clear cut. The size is the same as a dime. Holes gnawed by rats are larger and the size is the same as a quarter. Rough torn edges are present.
- Rub marks – They will leave oil rub marks on the wall or floor when they travel along the walls. If smear rub marks are present, this means fresh rodents. Gnawed marks left on wood also can tell what they are. If there are some small scratch marks, they are probably the mice. If tooth marks are 1/8 inch long, they are probably the rats.
- Rodent Pathways – These common pathways are mostly along building foundations, interior walls, ledges, electrical wires, pipes, tree branches, fence rails and conduits.
- Nesting preference – Roof rats will build their nests above ground, like in the trees, attics, or dense vegetation, while Norway rats normally burrow deep in the ground outdoors. Mice tends to build their nests indoors and they love using soft shred paper, string, as well as other soft materials
- If any scratching sound is heard at night, mostly there are rodents that are scampering along floors or inside walls.
- Unusual Behavior of pets – When pets smell or hear rodents in home, they tend to act unusual. If they become unusual alert, bark, or behave what they don’t do regularly.
Knowing the right type of rodents in the home can help you choose the right method to get rid of them.
