The Tempo WP Ultra Pest Control Insecticide features Cyfluthrin at 10% as its active ingredient, which is known for its effectiveness against a variety of insects, including roaches. This product comes in a powder form and can be mixed to create between 21 to 42 gallons of insecticide, depending on the pest being targeted, making it a versatile choice for different infestation levels.

The residual effect is generally strong with Cyfluthrin, ensuring that treated areas remain protected for a considerable duration after application.

Safety is always a critical point; as with most insecticides, it is important to handle this product carefully and follow all label instructions to minimize risks.

The Harris Diatomaceous Earth Crawling Insect Killer, weighing 4 pounds, is designed to tackle a broad spectrum of insects, including roaches, fleas, ants, and bed bugs. One of its notable features is the inclusion of a powder duster, which simplifies the application process, allowing users to target hard-to-reach areas like cracks and crevices efficiently. The product boasts of being 100% freshwater diatomaceous earth, with no fillers or additives, emphasizing purity and potentially enhancing its effectiveness. Its long-lasting nature means that, as long as it remains dry, it can provide indefinite protection against unwanted pests, making it economically appealing for users looking for a sustainable solution.

The active ingredient, diatomaceous earth, works mechanically rather than chemically, which is generally safe for humans and pets when used correctly, addressing concerns about safety in home environments. However, users should ensure it is applied in dry areas, as moisture can reduce its efficacy significantly.

Its effectiveness is well-regarded, particularly for non-chemical pest control. Users need to be mindful of the application method to maintain its potency, which might require frequent reapplication in damp environments. It's also crucial to handle the powder carefully to avoid inhalation, despite being non-toxic. This product is ideal for those seeking a natural, long-term solution to pest issues, but users should be prepared for regular maintenance and attentive application in varied household environments.
