Place Products Properly
Placing mouse traps and bait stations in proper areas throughout your home are essential for the products to catch mice effectively. Understanding the high traffic areas and spaces that you’ve suspected mice to be entering from are the best places to set mouse traps and stations. Here are some tips on proper product placement:
- Place glue traps in suspected areas to see if those destinations are in fact frequented by mice.
- Look for areas with rodent droppings, gnaw marks and nesting material which are all clear indications of mouse activity.
- Be mindful of elevated areas such as storage cabinets, pipes, beams and false ceilings that mice can climb to.
- Always place traps and bait stations in areas that are out of reach from children and pet animals.
Use a Mix of Products
Setting enough mouse bait stations and traps in your home will ensure that you get rid of all mice in your home. Mice reproduce at a rapid rate and only require a few weeks to begin seeing offspring in your living space.
Read Label Instructions Carefully
Product packaging for all mouse traps and bait stations involve safety information and informative step-by-step instructions on how to properly use the product. It is important to follow the instructions carefully to effectively get rid of mice using the product.
Safely Secure Bait Blocks
When deciding to choose a bait station to get rid of mice, it is important to always secure bait blocks inside of bait stations for safety reasons. Bait blocks are highly poisonous and are harmful to pets and children who should not be in close contact with bait blocks at all. Bait stations securely keep bait blocks in place and are designed to be tamper-free.

Cleaning Your Home Post-Mice
Once you have gotten rid of all the mice in your home, it is important to properly clean and disinfect every area of your living space that mice may have occupied. Droppings and urine that mice leave behind can carry toxic pathogens that can greatly harm you, your family and your pets’ health. Here are a few items required in order to clean up after a mouse problem:

| Cleaning Supplies | Purpose |
|---|---|

Rubber Gloves and a Face Mask |
Avoid the possibility of skin irritation and the inhalation of pathogens that mice have brought into your home. |
|
Dustpan and Broom |
Sweep up all mouse droppings and other remnants that mice have brought into your home. |
|
Disinfectant Spray |
Disinfect all areas that mice were frequenting during their time in your home. This includes table surfaces, cabinets and floors. |
|
Paper Towel |
Use paper towels for wiping down surfaces and disposing of soiled paper towels easily. |
Disposal of Droppings
- Apply gloves and facemask.
- Sweep up any physical droppings that you find in your home and immediately dispose of the droppings in a garbage bag designated for the rat cleanup.
- Once the droppings are removed and disposed of in the garbage, spray all surfaces that rats have interacted with.
- Let the disinfectant spray settle into the surfaces for over 30 seconds before wiping down each surface. All paper towels used for wiping should also be disposed of in the garbage immediately.
Disposal of Dead Mice
Due to their nature of finding food sources in many places including unsanitary ones, mice can carry hazardous pathogens in their body. The pungent smell of a dead mouse in your home can toxicate the air in your living space and lead to health complications over time.
Using protective equipment and the other safety supplies to clean up after mice is important in removing dead mice from your home and safely disposing of them in the garbage without any chance of further spreading toxins in your home.
Preventing Mice From Coming Back Again
- Remove any sources of water and food to make it less enticing for mice to enter your home.
- Declutter your home and remove any potential areas that mice may consider nesting in. Boxes in basements and other storage areas are common places for rodents to burrow nests.
- Seal any potential areas that you suspect mice can be entering your home from. Doing so will significantly decrease the chances of mice in your home.
