Early spring is one of the busiest seasons for rodent control when many property owners start noticing renewed mouse and vole activity around their homes and businesses. Melting snow uncovers trails of dead grass made by voles tunnelling over the winter. Warm temperatures, exposed nests, and more food sources encourage mice and voles to explore new areas and establish fresh nesting sites.
Understanding why rodents become more active in spring and what early signs to watch for can help prevent costly damage and keep lawns and properties protected throughout the season.
Why Rodent Activity Increases in Early Spring
Mice and voles remain active throughout the winter, but most of their movement stays hidden beneath snow cover or inside warm structures.
Spring arrives and warm temperatures lead to:
- More food sources and plant growth
- Increased breeding behaviour
- Expanded foraging ranges
- New opportunities to enter structures
These changes make early spring a good time for proactive rodent control.
Mice versus Voles: Differences and Signs of Activity
While both mice and voles are small rodents that can have similar colourations, their appearances and behaviour have differences.
Mice
• Live indoors or outdoors and can get into walls and attics
• Active at night (nocturnal)
• Have slender bodies with pointy snouts, large and prominent ears, and long tails
• Make noise when they chew and run around
• Gnaw and leave chew marks on food and materials
• Eat plants and animal-related food (omnivores)
• Build nests with soft things and store food in undisturbed places
• Leave droppings the size of a grain of rice, urine, and an odour
Voles
• Live outdoors year-round
• Active during day and night
• Have fluffy bodies with a short and rounded snout, small furry ears, and short tails, compared to mice
• Can be bigger than mice and grow to 15 to 18 centimetres (6 to 7 inches) long
• Dig small holes in the ground
• Can damage lawns with tunnels that are visible after snow melt
• Eat plants and plant parts including grass, garden plants, roots, bulbs, and bark
Identifying the correct rodent pest helps your prevention and control strategy.
Rodent Damage
Property owners should regularly inspect their building interiors and exteriors for signs of rodents and prevent mouse and vole damage. Mice and voles reproduce quickly, and acting fast helps reduce long-term harm.
Structural Rodent Damage
Mice can damage property and spread disease. They can chew through drywall, insulation, wiring, and many types of food packaging. Mouse droppings and urine can contaminate food and surfaces, creating health hazards.
Lawn and Garden Rodent Damage
Under snow cover, vole tunnelling in grass can result in widespread turf damage if left unmanaged. During early spring when the snow melts, young trees are especially vulnerable to vole feeding damage. Mice and voles can eat and damage garden plants.
Practical Rodent Prevention Tips for Spring
A few targeted actions can greatly reduce the chance of rodents damaging your property.
1. Seal Entry Points
Mice can squeeze through openings as small as a dime. Inspect and repair exterior walls, doors, windows, vents, and where utilities enter structures. Fix door gaps with door sweeps. Fill holes using rust-proof metal mesh with caulking or spray foam.
2. Reduce Rodent Hiding Places
Keep the ground clear around building foundations and avoid growing bushes and tall plants too close. Reduce dense plant cover rodents could hide under. Keep grass trimmed and remove debris. Store construction materials and firewood up from the ground and away from buildings.
3. Remove Food Sources
Use secure garbage bins with tight-fitting lids, avoid feeding animals outdoors, rodent-proof compost bins, and remove ripened fruit from the ground. Minimizing available food is important for effective rodent control.
4. Protect Gardens
Use garden barriers and plant guards to discourage voles and mice from digging and chewing vegetation.
