Why Seguin

Why Seguin Homes Get Hit Harder Than Most

Mature pecan is a specific pest driver. The trees drop nuts and husks in quantity every autumn, which draws rodents and feeds squirrels heavily, and pecan aphids coat everything beneath with honeydew that wasps, ants and sooty mould follow. Limbs on old groves also reach roofs the trees long predate.

The Guadalupe adds the other half. River bottomland and mill races hold water and shaded cover through a hot summer, giving mosquitoes both breeding ground and daytime shelter, while 19th-century stone and timber around the square carries gaps at every junction that ageing buildings develop.

Common Questions

Seguin Pest Questions, Answered

Everything under the pecans is sticky.
That is aphid honeydew, and the sooty mould that grows on it. It is not itself a pest problem, but it draws wasps and ants to whatever sits underneath — cars, furniture, decking. Moving seating out from under the canopy in late summer does more than treating the insects it attracts.
Rodents arrive every autumn.
Nut fall is the reason, and it is a food supply on a scale no trapping programme matches. Clearing fallen pecans promptly is the single most effective thing, followed by sealing the building before the drop begins rather than after.
Squirrels getting into the roof.
Old groves put limbs over houses that were built long after the trees, so the route is usually a branch rather than a climb. Cutting limbs well back from the roof and closing the entry once the animals have gone is what breaks the pattern.
Mosquitoes even in a dry August.
River bottomland and the old mill races hold water when the rest of the county has dried out, and the shade there keeps adults alive between rains. Treating that shaded vegetation is what gives relief when the source is permanent water.
Termites in an old stone building.
Worth inspecting. Ageing mortar and timber junctions give subterranean colonies concealed routes to structural wood, and this part of Texas carries steady pressure. On a building this age the survey should cover moisture and decay in the same visit.
