A common question that we get asked is â€œwhy canâ€™t we just treat the cockroaches once and be doneÂ with it?â€
To answer that we need to understand the lifecycle of cockroaches and the environmental impactsÂ on cockroach treatments.
Most cockroaches grow their eggs in a sac called an ootheca, which is attached to the mother’sÂ abdomen.
The ootheca is an impermeable sacÂ that protects the eggsÂ
Additionally, if a mother carrying an ootheca feels sheâ€™s in danger, such as when she comes intoÂ contact with pesticides, sheâ€™ll drop the ootheca in order to protect it. If itâ€™s left in favourableÂ conditions (a warm, moist and protected area) the eggs can continue to develop and hatch whenÂ ready. A treatment that attacks the mother while sheâ€™s breeding is not guaranteed to kill herÂ offspring.from external threats. So whileÂ the eggs remain in the ootheca, no chemical treatment currently available can penetrate it.
Therefore, additional treatments are necessary at monthly intervals to kill newly hatched nymphs orÂ to prevent reinfestation.
The long-term effectiveness of a residual cockroach treatment is also impacted by a number of otherÂ factors:
- The type of surface to which it is applied will impact its adherence to the surface
- Temperature and humidity of the area can reduce the longevity of the treatment
- Â Cleaning programs or every-day use can wear or rub off the treatment
- Â Bad sanitation or housekeeping practices can attract more cockroaches to the area
Some of these factors are unavoidable, hence the need for additional treatments to control currentÂ populations of cockroaches and prevent reinfestation.
