5. Drawbacks of Using Soap Water in Killing Cockroaches

• Not 100% Effective: While soap water has its benefits, it’s not a guaranteed solution. Roaches are persistent and can find other sources of moisture to rehydrate, which might help them survive the soap water. 
• Can’t Reach Roaches in Hiding: One big challenge with soap water is that it can’t get into the hiding spots where roaches like to hang out, like cracks and crevices. So, while it might deal with the roaches you can see, it might not solve the whole infestation problem. 
• Takes Time: Using soap water takes some preparation, especially if you’re using bar soaps. If you have a widespread roach problem, you might need to make multiple batches, which can be time-consuming. 

Conclusion

The question of whether soapy water kills roaches has a promising answer. While it might not work for every infestation, it’s an eco-friendly, cost-effective, and safe way to deal with these unwanted pests.
