Which of the following is a chemical control method recommended for Oriental cockroaches?

Residual baits and micro-encapsulated pesticides are effective chemical control methods for Oriental cockroaches because they provide targeted and long-lasting effects by allowing the active ingredients to remain available over an extended period. Residual baits attract cockroaches, which then ingest the insecticide, leading to their extermination over time. Micro-encapsulated pesticides are designed to encapsulate the active ingredients, protecting them from environmental degradation and enabling a sustained release of the pesticide, which increases the likelihood of contact with the targeted pests.

In contrast, home remedies and essential oils may offer temporary relief but do not provide the effective, residual control that chemical methods can achieve. While pesticide traps might catch some individuals, they are less effective in the long term as a primary control method, particularly in warm areas where cockroaches can breed. Regular vacuuming and sanitation are essential for reducing pest populations and their food sources; however, they do not eliminate the pests themselves and should be used in conjunction with chemical control methods for the best results.
