Last Updated: November 26, 2025 | Texas Current Conditions

After 18 years as a Licensed Pest Control Applicator specializing in cockroach control, I've learned that cockroaches are the most difficult pest to eliminate without professional help. They multiply exponentially, hide expertly, and adapt to treatments rapidly.

Critical Warning Signs of Infestation

If you see cockroaches during the day in Texas, you have a severe infestation. Cockroaches are nocturnal—daytime sightings mean population pressure is forcing them into the open.

3. Musty odor (distinct "cockroach smell")
4. Egg casings (indicates breeding population)
5. Smear marks (dark streaks near water sources)
