What is a primary control method for German cockroaches?

The primary control method for German cockroaches focuses on targeted applications that reach their hiding spots. Crack and crevice applications involve using pesticides specifically designed to penetrate the tight spaces where cockroaches often reside, such as around baseboards, behind appliances, and in wall voids. This method is effective because it maximizes contact with the pests while minimizing exposure to other areas, reducing the risk of pesticide resistance and ensuring a more thorough treatment.

Fogging, while sometimes effective in larger areas or for certain pest control situations, typically does not target the specific hiding spots of German cockroaches and may not provide the level of contact needed for effective control. Spraying open areas might affect visible cockroaches but often misses the many hidden individuals that are crucial to eliminate for long-term management. Trapping can help monitor pest activity and reduce cockroach numbers but is often considered a supplementary method rather than a primary control strategy, as it does not directly eliminate infestations. Thus, using crack and crevice treatments is essential for effectively managing German cockroach populations.
