German Cockroaches: A Serious Threat
⚠️ Current Issue: Our building is experiencing an infestation of pesticide-resistant German cockroaches, which require a comprehensive management approach.
🔬 What Are German Cockroaches?
German cockroaches are small (½ to ⅝ inch long), light brown to tan insects with two dark parallel stripes behind their heads. They are the most common indoor cockroach species.
- Reproduce rapidly (up to 300 offspring per year)
