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.
