Birds are an essential part of Wisconsin’s wildlife, but when they take up residence in or around your home, they can cause more harm than harmony. Homeowners in Green Bay and across the state often face a variety of bird-related issues, particularly in the spring and summer months. From clogged vents to unsanitary droppings, bird problems can escalate quickly if not addressed. At Critter Control of Green Bay, we understand the unique challenges local homeowners face and how to prevent them humanely and effectively.
Common Bird Problems in Wisconsin Homes
Nesting in Vents and Chimneys
Birds like starlings, sparrows, and swallows often seek out warm, sheltered spots to nest—making vents, chimneys, and exhaust openings prime targets. While it may seem harmless, nesting in these areas can lead to serious complications. Blocked dryer vents and bathroom exhausts can cause poor airflow, moisture buildup, and even fire hazards. In chimneys, nests can create dangerous obstructions that lead to smoke damage or carbon monoxide buildup. Additionally, these nests often attract mites, fleas, and other pests, creating a health risk for the people inside the home.
Gutter and Roof Damage
Gutters offer another inviting nesting spot for certain bird species. Unfortunately, nesting materials and droppings can clog gutters, leading to water overflow that damages fascia boards, soffits, and shingles. Prolonged clogging can also result in water pooling around the foundation, potentially leading to structural issues over time. Birds frequently perched on rooftops can also contribute to wear and tear, especially when combined with the corrosive effects of droppings.
Bird Droppings
Accumulations of bird droppings aren’t just an eyesore—they pose real health and property risks. Droppings are highly acidic and can eat away at paint, metal, and stone surfaces, leading to costly repairs. They also carry harmful pathogens like histoplasmosis and salmonella, which can become airborne or be accidentally inhaled or ingested during cleaning. Areas like decks, walkways, and vehicles can quickly become unsanitary when used as regular perches.
Aggressive Behavior During Nesting Season
Many homeowners in Wisconsin report aggressive bird behavior during nesting season. Birds such as robins or swallows may become territorial and act defensively when they perceive threats to their nests. This can lead to swooping or dive-bombing behaviors that are especially alarming to children and pets. In some cases, outdoor areas may become nearly unusable until the nesting season is over, turning your backyard from a place of relaxation into a source of stress.
How to Prevent Bird Problems
While some bird presence is inevitable, there are several steps you can take to reduce the risk of serious issues. Prevention starts with understanding how birds choose their nesting sites and taking proactive steps to make your home less inviting.
Seal Entry Points
Inspect your home’s exterior regularly and seal any small gaps or holes near soffits, attic vents, or eaves. Installing vent covers and chimney caps made from durable metal mesh can effectively block birds from accessing these sheltered areas without disrupting airflow.
Gutter Guards and Roof Maintenance
Keep your gutters clear by installing bird-resistant gutter guards and cleaning them seasonally. Trim overhanging branches that provide easy access to your roof, and watch for signs of nesting activity like twigs, feathers, or droppings.
Bird Spikes and Netting
For areas where birds consistently perch or roost—such as roof edges, signs, or ledges—bird spikes offer a humane deterrent that makes it uncomfortable for them to land. Netting is another effective option for protecting balconies, patios, or garages from nesting attempts.
Limit Food Sources
Eliminate easily accessible food sources by securing garbage bins and avoiding outdoor feeding of pets. If you enjoy feeding wild birds, consider placing feeders farther away from your home to reduce nesting nearby.
Use Visual Deterrents
Birds are cautious creatures and can often be scared away with simple visual deterrents like reflective tape, predator decoys, or motion-activated devices. These can be especially useful during peak nesting season in the spring.
