The Second Round Of Baby Squirrels in Brampton: Late Summer To Early Fall

Updated: Jun 4

  • "The Second Round of Baby Squirrels in Brampton" refers to the phenomenon where a new batch of baby squirrels is born later in the year. Squirrels typically have two breeding seasons: one in early spring and another in late summer.

  • In Brampton, Ontario, Canada, the second round of baby squirrels usually occurs around late summer to early fall. This cycle ensures the population remains stable and helps the species adapt to seasonal changes. Residents may notice more young squirrels during this period as they explore and become more visible in their environment.

  • This phenomenon applies to Red Squirrels as well but is a bit more complicate. Red squirrels may not breed at all in a given year but are know to produce two litters in other years.

Yes, Squirrels Breed Twice Per Year Protect Your Brampton Attic Before The Mating Activity Starts Again

As a homeowner in Brampton, you know all too well the frustration that comes with scratching and scampering noises from your attic, especially when it's caused by eastern grey squirrels. These critters are known for their pesky behaviour, and understanding their breeding habits is key to protecting your home. Adult female squirrels produce multiple litters in their lifetime, with successful mating leading to even more offspring. This cycle of activity can cause significant damage to your attic and insulation. Protecting your attic before their breeding periods start again is crucial. Don't wait until it's too late – take action today and safeguard your home from these unwanted critters.

Overview of Grey Squirrel Breeding Seasons

The Eastern Grey squirrel is a fascinating creature but not always welcome in your home. Understanding their breeding patterns and timelines is crucial to maintaining a peaceful coexistence. Female grey squirrels have two primary breeding seasons yearly and are fiercely protective of their young. Knowing these seasons can help you prepare for any potential trouble ahead. The gestation period for a female squirrel is approximately 44 days, so it's crucial to take preventive measures well in advance. With this knowledge, you can have peace of mind knowing you're taking the necessary steps to protect your home. So…when do squirrels have babies? Read on…

#1 The First Breeding Season: Late Winter to Early Spring

As winter draws closer, eastern grey squirrels begin their first breeding season. If we have a seasonably warm winter, they could have them a bit earlier, but typically starting in late January and stretching into early March, this period is marked by increased activity as squirrels seek out warm, safe places to nest with a litter arriving soon, and your attic is a prime target. Newborn baby squirrels are born blind, hairless, and completely dependent on their mother for survival. Grey baby squirrels will develop fur within the first few weeks. The babies grow fairly rapidly, though; by eight to ten weeks old, they are venturing out on their own. By the age of eleven to twelve weeks, they are fully independent.

#2 The Second Breeding Season: Mid-Summer to Early Fall

The second breeding season occurs from mid-summer to early fall, usually between July and September. This season differs slightly as squirrels seek shelter from the summer heat and, later, a place to keep warm as temperatures drop. As with the spring litter, these squirrel babies are also born hairless and blind. They, too, rely on their mother’s milk to sustain them and become cute, furry creatures by the second week of life.

Why Red Squirrels and Grey Squirrels Choose Attics

Attics provide an ideal nesting ground for grey squirrels due to their warmth, safety from predators, and proximity to food sources. Common entry points include roof vents, gaps in the eaves, and small openings in your home's exterior.

Signs of Squirrel Infestation in Your Attic

Are you wondering if you've got uninvited guests? Listen for scratching and scampering noises, especially early morning or evening. Look for droppings, chewed wires, insulation damage, and nests made of leaves and twigs.

Potential Damage Caused by Squirrels

Squirrels can chew holes in shingled and wood to gain entry to an attic, once inside cause significant structural damage by gnawing on wooden beams and wires, which could lead to electrical fires. They also pose health risks due to their droppings and urine, which can contaminate your attic's insulation and air quality.

Preventive Measures Before Breeding Seasons Begin

Before each of the two breeding periods starts, conduct a thorough inspection of your home. Seal any potential entry points, trim overhanging branches that provide access to your roof, and keep food sources like bird feeders away from your house.

Effective Squirrel Deterrents

Natural repellents like peppermint oil, mothballs, or predator urine can keep squirrels at bay. Consider professional-grade deterrents like ultrasonic devices or exclusion barriers for a more robust solution.

What to Do If You Already Have Squirrels in Your Attic

If you suspect or confirm a squirrel infestation, act quickly. Humane removal methods, such as using one-way exclusion doors, can help. If the situation seems out of control, don't hesitate to call a professional wildlife control service.

Repairing Attic Damage Post-Infestation

After removing the squirrels, assess the damage. Repair chewed wires, replace contaminated insulation, and seal any entry points to prevent future infestations. A thorough cleanup is essential to eliminate any health risks.

Long-Term Squirrel Prevention Strategies

Regular maintenance is key to keeping your attic squirrel-free. Schedule periodic inspections, maintain your home's exterior, and stay vigilant, especially before and during the breeding seasons.

The Role of Professional Wildlife Control Services
