Spring, summer, and fall each bring distinct pest pressures to Galveston. The species and severity shift through the year in ways treatment programs should anticipate.
Why structural settlement creates rodent pathways
Foundation settlement in older homes creates hairline gaps where slab meets exterior wall. These gaps admit mice for the structural life of the home unless caulked or filled with copper mesh during the next maintenance cycle.
Industry guidance for Galveston-area conditions weights this factor higher than national pest control standards typically do.
3/8-inch openings and rodent access
Brick weep holes 3/8 inch wide admit mice readily into wall cavities. Stainless steel weep hole covers — designed for this specific purpose — exclude rodents without affecting the moisture drainage the weep holes provide.
Most Galveston homeowners discover this only after damage is visible. Earlier inspection changes that calculus.
When outdoor populations push toward structures
Cooler October-December weather drives outdoor rodent populations indoors. Pre-fall structural exclusion in August and September prevents the seasonal pressure before it begins rather than responding after rodents have established interior harborage.
This is one of the harder issues to catch early without a trained eye on the property.
Why parallel-placed traps fail
Snap trap effectiveness depends on trap orientation perpendicular to rodent run paths, not placement along the run path. Rats and mice step over traps oriented parallel to their travel direction without triggering them.
Routine inspection that explicitly checks this saves the cost of major remediation later.
Mixed-species activity in Galveston attics
Rat droppings in attics measure 1/2 to 3/4 inch long with blunt ends; mouse droppings measure 1/8 to 1/4 inch with pointed ends. Mixed-size droppings indicate multi-species activity that single-species traps won't fully address.
Industry guidance for Galveston-area conditions weights this factor higher than national pest control standards typically do.
