Mouse Treatment Guide

About Mice

The House Mouse (Mus Musculus) generally live in urban areas as they are closely associated with humans. The House Mouse varies in colour from grey, brown to black and is significantly smaller than a Rat with a body that is only 60mm – 100mm long. They have large round ears and a pointed nose. Their tails are scaly and are generally about the same length as their body.

Why are Mice a problem?

Mice have the potential to spread disease, viruses and bacteria to humans. They also can cause substantial damage to our homes and property, often chewing through wiring in cars and homes and food packaging. Learn how to get rid of mice using our simple treatment steps.

Inspecting for Mice

Unlike some other pests, you may not always sight a mouse to determine you have an infestation. It is for this reason it is important to inspect your home thoroughly and look out for these signs:

• Droppings Mouse droppings are small and dark with pointed ends, usually around 3-6mm long
• Damage Mice can be very destructive, gnaw marks are evidence of an infestation these could be on things such as wood, insulation and electrical cabling as well as food packaging
• Grease Marks These occur when rodents fur rubs against walls/floors/skirting boards on routes that they regularly travel
• Noises As mice are nocturnal you may hear noises such a scratching or squeaking during the night
• Strong Smell of Urine

Pre-Treatment Measures

• Remove excess vegetation in your yard, particularly anything that overhangs your property.
• Remove unnecessary debris within the yard that could be used as harbourage by mice. This could include things such as old buckets, lawn & tree clippings and timber piles.
• Ensure there are no potential access points in the structure of your home, mice can enter through a hole the size of a little “pinky” finger.
• Use a bin with a lid that can be sealed and empty these regularly (preferably before going to bed every night).

How to Get Rid of Mice 

Option 1. Baiting

There are a few key choices to be made when selecting the right bait. These can be broken down into two main categories:

1. Active Ingredient
2. Bait Formulation

Active Ingredient

For heavy rodent infestations and during rodent season (late April-August) it is recommended a powerful active such as Brodifacoum in Ratshot Red should be used. This ensures quick population control and a pulse baiting system which helps prevent resistance.

For all other months (September-March) and in sensitive baiting areas, such as where non-targets such as pets could be at risk, it is recommended the less toxic active Difenacoum in Ratshot Blue is chosen.

Bait Formulation

The key consideration in selecting the correct bait formulation will depend on the area you are wanting to place the baits. Of course, all bait types can be used in almost any baiting situation around the home it is important to understand where you can have a strategic advantage in controlling mice.

Paste Baits are fantastic for use around kitchens and areas where there are competing food sources that are not able to be removed as they are highly attractive to both Rats and Mice. Paste baits can also be used where other baits have not been taken/ been rejected by rodents.

Block Baits are very durable and long lasting so can be used in hot/cold/damp/dry areas such as around the exterior of your property for perimeter baiting, secured in roof voids and in areas where the bait must be secured.

Grain Baits are great for controlling mice particularly in areas where mice are already used to feeding on grain, for example in storage sheds.

Baiting Tips

• Use gloves when handling bait to avoid bait contamination
• Always use bait stations
• Monitor bait stations for bait uptake and replenish bait as necessary 

• If bait is taken rapidly or continually requires replenishment this may indicate a high rodent population. Ratshot Red is recommended for use where high rodent populations exist

Option 2. Traps 

Mouse Traps are a great non toxic way to control mice. There are a range of mousetraps available and which one to use will largely depend on personal choice.

Bait and set traps, placing the mouse traps in identified runways. Rodents tend to travel along walls so placement along walls is ideal:

• Victor Easy Set Mouse Traps should be placed with the baited pedal against the wall.
• Tunnel traps such as Victor Clean Kill and Victor TriKill should be placed against the wall so that the mouse can run straight into them.
• Rat Zapper Electronic Rat Trap hould be placed against the wall so that the mouse can run straight into them.

For best results use multiple traps placed at intervals of 0.5-1m.

Always read product label prior to use.
