During a pest inspection, pyrethrins and pyrethroids are chemical active ingredients commonly used to control insects by targeting their nervous systems, causing rapid paralysis and death. Pyrethrins are natural extracts from chrysanthemum flowers, while pyrethroids are synthetic, man-made versions with similar, but often enhanced, potency and stability. Pest control professionals use both in treatments for a wide range of pests, and inspection may involve identifying the type of product being used and its effectiveness against the specific pests found.
Pyrethrins
Origin: Derived naturally from chrysanthemum flowers.
Action: Rapidly paralyzes and kills insects on contact.
Degradation: Breaks down relatively quickly, with a short residual effect.
Use: Often used in organic gardening and home pest control products.
Pyrethroids
Origin:
Synthetic, man-made chemicals that copy the structure of natural pyrethrins.
Action:
Targets the insect's nervous system.
Advantages:
Offer greater potency and stability than natural pyrethrins, making them a cost-effective and convenient choice for pest control professionals.
Use:
Widely used in both agricultural and public health programs, and for controlling common household pests like cockroaches and ants.
What a Pest Inspector Looks For
A pest inspector will look for evidence of pest activity and then determine the most appropriate treatment method.
Pest Identification:
Identifying the specific pests to choose the correct chemical and treatment strategy.
Chemical Application:
If pyrethrins or pyrethroids are used, the inspector will know how to apply them effectively and safely.
Treatment Effectiveness:
They will also know how these chemicals work and how to determine if they are still active or have degraded, according to the U.S. Environmental Protection Agency (EPA).
Key Considerations
Safety:
While pyrethrins have low mammalian toxicity, proper handling and application are crucial.
Environmental Factors:
Applications should be carefully considered, especially in sensitive areas.
Regulations:
The EPA regulates these chemicals, ensuring they are used according to specific labeling and safety guidelines.
