Pest-Blok™ by HY-GUARD EXCLUSION®, created in conjunction with Pest-Blok inventor Will Langman, is a new product line made to block pests from entering metal roofs, metal siding, and vinyl siding corners.
Launching in Spring 2026, the Corrugated Exclusion Strip™ covers almost three feet at a time, removing the need to install small inserts between every rib. It seals the open gaps in metal roof panels at the ridge and along the bottom edges.
Four distinct strip profiles are available, engineered for each common metal panel type:
And each strip profile comes in two versions:
But what makes these panel systems different? And how do you know which one you’re working with?
Agricultural panels (often referred to as ag panels) are versatile, durable, and cost-effective metal roofing and siding systems with visible screws.
Key identifiers (dimensions may vary)
Common uses
Why you’re likely to encounter this panel system
Why this matters for pest and wildlife pros: Ag panels have larger, more irregular gaps — prime entry points for birds, bats, rodents, and insects.
Commercial panels balance performance, appearance, and energy efficiency. They’re used where aesthetics and code compliance matter.
Key identifiers (dimensions may vary)
Common uses
Why this panel system is commonly used
Why this matters for pest and wildlife pros: Tighter profiles still leave consistent gaps along ridges and eaves where nesting birds and insects enter.
Industrial panels are thicker, stronger systems built for large facilities and harsh conditions.
Key identifiers (dimensions may vary)
Common uses
Why this profile shows up on large facilities
Why this matters for pest and wildlife pros: Larger ribs create deeper voids, which are ideal for birds, starlings, pigeons, and larger rodents to get inside.
Standing seam panels are a premium roofing system with raised vertical seams and concealed fasteners for maximum water protection.
Key identifiers (dimensions may vary)
Common uses
Why does a homeowner choose standing seam panels?
Why this matters for pest and wildlife pros: Standing seam roofs have fewer fastener penetrations but still leave consistent ridge and edge gaps pests exploit.
Every metal panel system has both a different profile and different gaps that pests can exploit.
The Corrugated Exclusion Strip from the Pest-Blok by HY-GUARD EXCLUSION line is designed to match each system precisely, whether you're working with agricultural, commercial, industrial, or standing seam panels.
With the right profile at the ridge or lower edge, you can:
One strip. Fewer steps. Stronger protection.
