Headline is misleading because the conclusion is premature. There are other obvious reasons why the roach population may not be decreasing, other than adapting to pesticides: 1. Incomplete treatment -- apartment buildings are large and exterminators likely can't access all interior spaces, providing ample breeding ground. 2. Reinfestation from outside sources -- roaches live in all kinds of tight spaces (e.g. corrugated cardboard boxes), and the number of people in an apartment virtually guarantees cross-contamination. 3. Inadequate amount of pesticides applied. I'm hesitant to jump to the conclusion that neurotoxins are failing without removing other, much more likely factors.
