<p>Seeing baby roaches after extermination can be concerning, but it doesn’t necessarily mean the treatment failed. Here are four reasons why they may still appear:</p><p>Egg Cases Survived the Treatment<br />Many insecticides do not kill cockroach eggs, which are protected inside oothecae (egg cases). After extermination, these eggs can still hatch, leading to the presence of baby roaches.</p><p>Hidden Infestation Areas<br />Cockroaches are experts at hiding in cracks, crevices, and other hard-to-reach areas. Some may have escaped the initial treatment and later emerged, especially if their hiding spots were not directly treated.</p><p> </p><p>Residual Pesticide Is Working<br />Many pest control treatments use residual insecticides that continue killing roaches over time. Baby roaches appearing after extermination may be newly hatched and will soon die upon contact with the treated areas.</p>
