Bat Removal in New Construction Utah — Why New Homes Get Bats Too

Many Utah homeowners assume bats only target old, drafty houses. In reality, some of the most active bat removal markets in 2026 are Utah’s newest developments: Lehi, Herriman, Eagle Mountain, Saratoga Springs, and Vineyard. Here’s why new construction is vulnerable — and what to do about it.

Why New Construction Attracts Bats

Displaced Colonies Colonize New Structures

Utah’s rapid residential expansion has built subdivisions on top of former agricultural land, desert terrain, and areas that were bat habitat for decades. The bats don’t disappear — they move to the nearest available structures, which are the new homes being built in their former territory.

Construction Gaps in New Homes

Even perfectly built new homes have bat entry points:

• Ridge vent systems: Most new Utah homes use continuous ridge vents — the gap between the vent and the roofing material is a bat entry point in most systems
• Builder-installed vent screens: Factory screens on gable vents are often lightweight aluminum that bats can deform or find gaps around
• HVAC penetrations: AC condenser line sets, HRV ducts, and exhaust vents create exterior penetrations that builders often seal with expanding foam — which degrades within 5–7 years
• Garage-to-house connections: The garage attic often connects to the main attic through unsealed penetrations

Aging Construction Materials (10–15 Year Mark)

Homes built in Utah’s 2005–2015 building boom are now entering the age range where original sealants shrink, foam degrades, and ridge vent systems develop the gaps that bats exploit. This is fueling a significant wave of bat removal demand in previously “new” neighborhoods.

High-Risk New Development Areas in Utah (2026)

• Lehi / Silicon Slopes: Built on former agricultural land adjacent to Point of the Mountain bat corridors
• Herriman: Oquirrh Mountain base — displacing canyon bat colonies since 2005
• Eagle Mountain: Desert plateau development with large bat populations in undeveloped adjacent land
• Saratoga Springs: Utah Lake wetlands adjacent — high bat foraging activity throughout the year
• Vineyard: Utah Lake shoreline — maximum bat foraging pressure

Prevention for New Construction in Utah

• Install commercial-grade ridge vent covers (not builder-standard foam baffles) rated to exclude bats
• Use hardware cloth (½ inch galvanized mesh) on all gable vent openings rather than thin aluminum screens
• Seal all HVAC penetrations with permanently bonded materials rather than expanding foam
• Schedule an inspection 10 years after construction to check for emerging vulnerabilities
