Community Tips
Apply perimeter insecticide in a continuous band 12 inches wide and 6 inches deep along the foundation, focusing on entry points like utility penetrations and foundation cracks where pest activity concentrates. Spectracide Triazicide ($12-18) provides residual protection for 3 months and works against both crawling and flying insects without requiring repeat applications weekly.
Never spray perimeter insecticide during rain or within 24 hours before forecasted precipitation, as runoff reduces effectiveness and can contaminate soil drainage systems. Most formulations require a dry barrier to establish the 30-60 day protective zone manufacturers guarantee.
Budget $40-80 for a complete foundation treatment on a typical 2,000 sq ft home, accounting for two seasonal applications (spring and fall) using concentrate-based products like Talstar P ($25-35) that yield more coverage per dollar than ready-to-spray alternatives. ---
