Birds nesting in walls of a house can cause damage and noise; it’s essential to safely remove them and seal entry points to prevent future infestations.
Discovering birds nesting inside your home’s walls can be frustrating. These uninvited guests cause damage and create noise. This guide explains effective, humane solutions to remove them and prevent future invasions.
Why Birds Enter House Walls
Birds seek shelter in wall cavities for several reasons:
- Protection from predators and weather
- Warm nesting spots during breeding seasons
- Accessible entry points in your home’s exterior
Common culprits include sparrows, starlings, and woodpeckers. Some species peck at mortar for grit to aid digestion. Others remove material for nest building.
Signs of Birds in Walls
- Chirping or scratching sounds
- Visible holes or damaged mortar
- Nesting materials near vents or gaps
- Increased bird activity near specific wall areas
Humane Removal Methods
Never seal birds inside walls. Follow these ethical removal steps:
1. Locate the Entry Point
Inspect your exterior for gaps larger than 1/2 inch. Common access areas include:
- Loose siding
- Damaged roof vents
- Cracked mortar joints
- Gaps around pipes or cables
2. Encourage Birds to Leave
Try these non-harmful deterrents:
- Install bird deterrent devices near problem areas
- Use reflective tape or shiny objects to scare birds
- Play recorded predator calls intermittently
3. Provide Alternative Nesting Options
Divert birds to better locations:
- Install proper birdhouses away from your home
- Create a designated grit station with sand and crushed eggshells
- Maintain shrubs and trees that offer natural nesting spots
Preventing Future Infestations
After removing birds, take these preventive measures:
| Problem Area | Solution |
|---|---|
| Mortar gaps | Repoint with fresh mortar containing deterrent additives |
| Roof vents | Install mesh screens or specialized vent covers |
| Siding gaps | Seal with expanding foam or hardware cloth |
| Chimneys | Install proper chimney caps |
Long-Term Deterrents
Consider these permanent solutions:
- Apply bird-resistant paint or coatings to vulnerable surfaces
- Install physical barriers like netting or spikes in problem areas
- Maintain your property to eliminate attractive nesting spots
When to Call Professionals
Seek expert help in these situations:
- Large infestations or persistent problems
- Protected bird species involved
- Structural damage requiring repair
- Inaccessible nest locations
Professional wildlife removal services have specialized tools and knowledge to handle bird problems humanely and effectively. They can also help identify and seal all potential entry points.
Legal Considerations
Many bird species are protected by law. The Migratory Bird Treaty Act makes it illegal to disturb active nests of native species. Always check regulations before taking action.
Repairing Bird Damage
After addressing the bird problem, repair any damage:
- Clean affected areas thoroughly
- Replace damaged insulation
- Repair or replace compromised structural elements
- Apply protective coatings to prevent future issues
For severe damage, consult a contractor specializing in wildlife damage repair. They can ensure proper restoration and recommend additional preventive measures.
