Types of Rats/Rodents

There are several types of rats commonly encountered, each with distinct characteristics. The Norway rat, or brown rat (Rattus norvegicus), is large and robust with a blunt nose, small ears, and a short tail, thriving in burrows and sewers. In contrast, the roof rat, or black rat (Rattus rattus), is smaller and more agile, featuring a slender body, pointed nose, and large ears, often found in attics and upper levels of buildings. Both types are adept survivors, causing significant damage and posing health risks in urban environments.Here are the main types:

DIY Home Remedies to Control Rats and Mouse!

---

Some Tips to Control Rats and Mouse:

• Peppermint Oil: Soak cotton balls in peppermint oil and place them in areas where you've seen rodents. The strong smell deters them.
• Ammonia: Mix two cups of ammonia, two spoons of detergent, and a quarter glass of water. Place it in a small dish near rat-prone areas. The strong smell will repel them.
• Steel Wool: Seal any holes or entry points with steel wool. Rodents can't chew through it.
• Mothballs: Place mothballs in areas where rodents frequent. The smell is repulsive to them.
• Hot Pepper Flakes: Sprinkle hot pepper flakes around entry points and rodent hotspots. The spiciness deters them.
• Onions: Place slices of onions in areas where rats and mice are active. The smell is off-putting to them.
• Garlic: Mix garlic with water and spray the solution around your home to deter rodents.
• Plaster of Paris and Cocoa Powder: Mix equal parts of plaster of Paris and cocoa powder. When rodents consume it, the plaster hardens inside their stomachs.
• Bay Leaves: Scatter bay leaves in your pantry and other areas. Rodents dislike the scent.
• Pepper Spray: Mix hot pepper sauce with water and spray it around baseboards and rodent entry points.
• Used Cat Litter: Place containers of used cat litter around your home. The smell of cat urine will deter rodents.
• Cloves: Place whole cloves in areas where rodents are a problem. The strong scent repels them.
• Ultrasonic Devices: Use ultrasonic repellent devices that emit high-frequency sounds to deter rodents.
• Cucumber Slices: Place cucumber slices around rodent-prone areas. They dislike the smell of cucumber.
• Dried Snake Litter: Obtain dried snake litter from a pet store and place it around your home. The smell of predators scares away rodents.
• Baking Soda: Mix baking soda with sugar and flour. When rodents eat it, the baking soda reacts with the acid in their stomachs, causing a fatal gas buildup.
• Cayenne Pepper: Sprinkle cayenne pepper in areas where you've seen rodents. They dislike the spiciness.
• Talcum Powder: Sprinkle talcum powder around suspected entry points to track rodent activity and block their paths.
• Vinegar: Soak cotton balls in vinegar and place them around rodent hotspots. The strong smell deters them.
• Essential Oils: Use essential oils like eucalyptus, citronella, or tea tree oil to deter rodents. Place a few drops on cotton balls and distribute them around your home.
