Bat exclusion is difficult work.
It takes years of experience to learn how to locate all the openings bats are using, recognize primary entry points, and set excluders properly in high, awkward, difficult areas of a house.
If an excluder is installed wrong, bats can be blocked in, injured, trapped, or killed. Proper bat exclusion also depends on the house being bat-proofed first, with the secondary gaps and potential entry points closed before excluders are set over the main active openings. This is one of the reasons real bat control is so difficult: it is not just a product you buy online. It is a skilled process that has to be done safely, properly, and legally.
These are ours….
They are the result of more than 3 decades of trial and error. We developed them specifically because there was nothing on the market like them.
Not all bat excluders are safe, and not all bat excluders work.
Most bat excluders sold online are cheap plastic gadgets. Many excluders installed by non-specialist wildlife companies are made from mesh, pipe, netting, plastic tubes, caulking tubes, or whatever else they can force over an opening.
That is not professional bat exclusion.
At Bat Control Specialists, we use custom aluminum, laser-cut bat excluders designed for real residential bat work. They are stronger, safer, more durable, and more adaptable than the cheap plastic excluders sold online or the dangerous mesh tubes often used by general wildlife companies.
Our excluders are designed to let bats leave safely without getting stuck, injured, or killed.
Cheap Plastic Excluders Are Not Built for Real Houses
Cheap plastic bat excluders may look simple online, but real houses are not simple.
Bat entry points are rarely flat, square, easy-to-reach holes. They are often located high on the structure, under roof edges, beside chimneys, at soffit and shingle intersections, around fascia, behind flashing, under siding, or in awkward corners with compound angles.
Plastic Excluders Can Be Destroyed by Sun & Weather.
Plastic does not do well in direct sunlight and weather exposure.
Cheap plastic bat excluders can become brittle in the sun, crack, warp, loosen, or break down over time We see this often with cheap plastic excluders sold online or installed by non-specialist companies.
Once the plastic is damaged, the excluder no longer works and worse,
The bats can get back in.
That is why we do not rely on cheap plastic excluders as a professional solution. A bat excluder must hold up long enough to let the bats leave safely and prevent them from re-entering until the job is finished.
Excluders are often too stiff, generic, too fragile and prone to weather and rodent damage, and too limited to work well on real bat entry points. They are designed like one-size-fits-all gadgets, but bat entry points are not one-size-fits-all.
And then there is the mouse issue.
In my experience, every house with bats also has mice.
When a house is bat-proofed, mice often find their way out through the same one-way doors used for the bats.
The difference is that bats can fly away once they exit.
Mice cannot.
When a mouse reaches the end of a plastic bat excluder, it often decides not to jump, so it tries to chew its way out through the side instead.
This is one of the reasons we regularly find cheap plastic bat excluders damaged or destroyed by mice. Plastic excluders are not built for real houses, real rodents, or real bat-control work.
This plastic bag-style bat excluder was chewed through by mice. Once rodents damage cheap plastic excluders, bats can get back into the structure.
And There Are Mesh Excluders Made By Hacks.
Mesh Excluders Can Trap, Injure, and Kill Bats
Mesh excluders are dangerous period.
The reason wildlife companies use mesh is obvious: it is easy to bend, fold, wrap, and force around awkward openings. Bat entry points are often in difficult places, and mesh seems like an easy way to cover compound angles around soffits, shingles, chimneys, rooflines, and fascia.
But that flexibility is exactly what makes mesh excluders dangerous.
Mesh can have sharp edges, burrs, twisted wire, snag points, and narrow areas where bats can become trapped. Bats can catch their wings, feet, claws, or bodies in the mesh. They can become stuck, injured, or killed.

And The Lethal Results.

Mesh excluders can trap, injure, or kill bats when they are badly made or poorly installed.
A proper bat excluder should never become a trap.
Our Custom Aluminum Excluders Are Safer for Bats
Smooth custom aluminum excluders.
A proper bat excluder lets bats leave safely without snagging, trapping, or injuring them.
Our custom aluminum excluders are designed so bats can pass out safely.
They are smooth, solid, and shaped to allow bats to leave the opening without getting caught on sharp mesh, twisted wire, loose netting, or broken plastic. Bats can crawl out through the excluder and drop away from the structure, but they cannot turn around and get back inside.
That is the whole point of a proper one-way bat door.
The excluder should let bats out safely.
It should not injure them.
It should not trap them.
It should not kill them.
Our smooth aluminum excluders allow bats to leave safely without becoming stuck in mesh or injured by sharp edges.
Smooth and safe.
Ready for action
We Use Different Excluder Designs for Different Bat Entry Points
One of the biggest advantages of our excluders is that they are not one-size-fits-all.
A bat entry point under a soffit is not the same as a gap beside a chimney. A roof valley is not the same as a shingle edge. A gap below a window is not the same as a roofline opening beside a gutter. Some entry points are vertical. Some are horizontal. Some are under overhangs. Some are on steep roofs. Some are tucked behind flashing or buried in awkward corners.
Cheap plastic excluders do not handle these situations well.
Our aluminum excluders can be made in different styles, shaped for different applications, and modified on site to fit the actual opening. That matters because bat exclusion only works when the excluder fits the entry point properly.
Designed for Awkward, High, Real-World Bat Entry Points
Bat entry points are often in the worst possible places.
They may be high on a ladder, under a steep roofline, beside a chimney, under shingles, inside a roof valley, around a soffit corner, or tucked into a narrow gap where several building materials meet.
These are not clean, flat, easy openings.
They involve compound angles, uneven surfaces, shingles, metal flashing, brick, siding, soffit, fascia, caulking, roof edges, gutters, and trim.
That is why off-the-shelf excluders are so often useless. They are not designed for the real places bats actually use on houses.
Our excluders are built for that reality. They can be fitted, shaped, adjusted, and installed in awkward areas where cheap plastic excluders do not work and mesh excluders become dangerous.
Bat entry points are often high, awkward, and difficult to access. Our excluders are designed for real rooflines.

Color-Matched and Built to Look Professional
A bat excluder is temporary, but it still needs to look professional while it is in place.
Our aluminum excluders can be color-matched to the house when appropriate, so they do not look like a cheap plastic tube or a wad of mesh hanging off the roofline.
That matters to homeowners.
It also matters because professional bat work should look like it was done by someone who understands both bats and houses.
And bluntly homeowners can leave excluders up for years. Not
Why Non-Specialist Wildlife Companies Use Mesh
Many general wildlife companies use mesh because it is cheap and easy to bend around awkward openings.
That does not make it safe.
Bat entry points are often difficult to reach and difficult to cover. Mesh lets someone quickly wrap, fold, and staple something over a gap without designing a proper excluder for the opening.
The problem is that bats are not raccoons or squirrels. They are small, delicate animals with wings, claws, and bodies that can easily snag in badly shaped mesh.
That is why cheap mesh tubes can become deadly.
A professional bat excluder should be designed around bat safety, not just installer convenience.

Mesh excluders are often dangerous.
Our excluders are designed by bat specialists for real residential bat problems.
The Excluder Is Only as Good as Its Design and Installation
A bat excluder has to be safe, durable, properly shaped, and installed over the correct opening.
If it is too small, bats may get stuck.
If it is too sharp, bats may get injured.
If it is made of mesh, bats may become trapped.
If it is plastic, mice may chew it apart.
If it does not fit the opening, bats may get around it.
If it is installed in the wrong place, it does nothing.
That is why proper bat exclusion requires more than a cheap tube from the internet. It requires experience, custom equipment, and an understanding of how bats actually use houses.
