Pest Guard Insulation vs. Standard Fiberglass: What Hampton Roads Homeowners Need to Know

Attic insulation is selected for the home and installation conditions. Pest Guard™ is a borate-treated fiberglass option described as intended to deter certain insects. We do not have the current product label or manufacturer documentation available to confirm specific target insects, safety or efficacy claims, or treatment duration.

How Standard Fiberglass Insulation Works

Standard blown-in fiberglass insulation is made from spun glass fibers that trap air, creating a thermal barrier. It is the most widely used attic insulation material in the United States. Fiberglass is durable, moisture-resistant, non-combustible, and doesn't settle as aggressively as cellulose over time. It performs well thermally and is reasonably priced. What it does not do — in any form — is discourage pests. Fiberglass is an inert material. Insects and rodents burrow through it freely, nest in it, and move through it without any deterrent effect. In a region like Hampton Roads, where the warm climate supports year-round pest activity, this is a significant limitation.

What Makes Pest Guard™ Different

Pest Guard™ insulationis described as fiberglass treated with a borate blend. We do not have product-specific documentation to verify its formulation, concentration, biological mechanism, or safety profile. Consult the current label and manufacturer instructions for those details.

Pest Guard™ is described as intended to deter certain insects, but the current label is needed to confirm which insects it lists and what efficacy claims are supported. We also cannot confirm its treatment duration or compare it with topical products without manufacturer documentation.

Why This Matters Specifically for Hampton Roads

Hampton Roads has one of the highest pest pressures of any metro area in Virginia. The warm, humid coastal climate supports year-round activity for most insect species, including German cockroaches — one of the most destructive attic insects because they reproduce rapidly and travel extensively through wall cavities. Virginia Beach, Chesapeake, and Norfolk consistently rank among the most cockroach-active markets in the state according to pest control industry surveys. Rodents — roof rats and squirrels — are also a persistent problem in attic insulation across the region.

Pest Guard™ should not be treated as a substitute for pest inspection, treatment, or exclusion. Ask for its current label to confirm the product's intended use.

Pest Guard™ vs. Standard Fiberglass: Side-by-Side

• Thermal performance (R-value):Equivalent — both achieve R-49+ when installed to appropriate depth
• Pest-related use:Pest Guard™ is described as intended to deter certain insects; consult the current label for listed insects and approved use
• Moisture resistance:Both are moisture-resistant; neither should be installed over existing wet insulation
• Safety:Consult the specific product label and manufacturer instructions
• Treatment duration:Confirm with the current Pest Guard™ label and manufacturer documentation
• Cost:Pest Guard™ carries a modest premium — typically 10–15% over standard blown-in fiberglass
• Availability in Hampton Roads:Standard fiberglass — widely available. Pest Guard™ — through Universal Insulation Doctor

Who Should Choose Pest Guard™?

Whether Pest Guard™ is appropriate depends on the product label, the home, and the homeowner's needs. Request the current label and a project estimate before deciding. It is not a replacement for pest treatment or exclusion. Consider it if:

• Homes that have previously had pest issues in the attic
• Properties near wooded areas, water features, or coastal marshland
• Older homes where pest entry points in the roofline have been harder to fully seal
• Any homeowner who values peace of mind and doesn't want to think about it again
