A common question that we get asked is “why can’t we just treat the cockroaches once and be done with it?”
To answer that we need to understand the lifecycle of cockroaches and the environmental impacts on cockroach treatments.
Most cockroaches grow their eggs in a sac called an ootheca, which is attached to the mother's abdomen. The ootheca is an impermeable sac that protects the eggs from external threats. So while the eggs remain in the ootheca, no chemical treatment currently available can penetrate it.
Additionally, if a mother carrying an ootheca feels she’s in danger, such as when she comes into contact with pesticides, she’ll drop the ootheca in order to protect it. If it’s left in favourable conditions (a warm, moist and protected area) the eggs can continue to develop and hatch when ready. A treatment that attacks the mother while she’s breeding is not guaranteed to kill her offspring.
Therefore, additional treatments are necessary at monthly intervals to kill newly hatched nymphs or to prevent reinfestation.
The long-term effectiveness of a residual cockroach treatment is also impacted by a number of other factors:
Some of these factors are unavoidable, hence the need for additional treatments to control current populations of cockroaches and prevent reinfestation.
