Regional Pest Pressure Guide for Dallas, TX

What this means if you live in Dallas: hardiness zones measure the average coldest temperature an area sees each winter — which directly determines whether insects and their eggs survive the cold season or die off and have to reestablish each spring. Dallas's winters are about middle-of-the-pack (#8 of 20 we track) for mildness. Milder winters mean less die-off, so pests here get a head start each spring and stay active over a longer stretch of the year than in a colder city — worth factoring into how early you schedule preventive treatment, not just how you react to an active problem.
