Why Greatstuff And Squirrels Is Necessary

From my experience, Greatstuff and squirrels go hand in hand when it comes to protecting my home. Squirrels are persistent little creatures that find the tiniest gaps and holes to squeeze through, often causing damage inside walls or attics. Using Greatstuff to seal these entry points has been a game changer for me—it not only blocks their access but also helps insulate my home better.

I’ve noticed that without properly sealing these openings, squirrels can create nests that lead to noise, unpleasant odors, and even structural damage. Greatstuff provides a quick, effective solution that fills cracks and holes securely, preventing these pests from returning. For anyone dealing with squirrel problems, I’d say this combination is essential for keeping your home safe and peaceful.

My Buying Guides on Greatstuff And Squirrels

When I first encountered squirrels causing damage around my home, I knew I had to find an effective solution. GreatStuff, the expanding foam sealant, quickly became my go-to product for blocking their entry points. Here’s what I’ve learned through my experience and research to help you make the best purchase and use it effectively.

Understanding GreatStuff and Its Use Against Squirrels

GreatStuff is a polyurethane foam that expands to fill gaps, cracks, and holes. Because squirrels often enter homes through small openings, sealing these is essential. I found that GreatStuff provides a quick and durable fix that deters squirrels from squeezing back in.

Choosing the Right GreatStuff Product

GreatStuff comes in various formulas, so I recommend selecting the one best suited for outdoor use and larger gaps. For example:

  • GreatStuff Pestblock: Specifically designed to keep pests like squirrels, rodents, and insects out.
  • GreatStuff Pro Gaps & Cracks: Ideal for smaller holes and cracks around the house.

I always check the label to ensure it’s weather-resistant and safe for the intended application area.

Important Features to Look For

From my experience, these features made a big difference:

  • Expansion Strength: It needs to fill gaps completely without shrinking.
  • Durability: Exposure to outdoor elements means the foam should last without degrading.
  • Non-Toxic Once Cured: Important for safety around pets and children.
  • Ease of Application: A straw applicator helps target specific spots without mess.

Preparing the Area Before Application

Before using GreatStuff, I made sure to:

  • Clean the area thoroughly to remove dirt and debris.
  • Locate all possible entry points squirrels use.
  • Wear gloves and protective gear, as the foam can be sticky and hard to remove.

Complementary Measures Alongside GreatStuff

Sealing gaps is just part of the solution. I also recommend:

  • Trimming tree branches near your roof to prevent easy access.
  • Setting up squirrel deterrents like ultrasonic devices or natural repellents.
  • Inspecting and maintaining the sealed areas regularly.

Common Mistakes to Avoid

I learned the hard way that:

  • Applying GreatStuff in wet or extremely cold conditions reduces its effectiveness.
  • Overfilling gaps causes excess foam to expand and create a mess.
  • Not addressing all entry points leaves squirrels a way back in.

Final Thoughts

Using GreatStuff to block squirrels worked well for me, but patience and thoroughness are key. It’s a practical, affordable method to protect your home when combined with other preventative steps. I hope my insights help you make an informed purchase and keep those pesky squirrels at bay!
