Bed bugs sprayed with Best Yet Organic Bed Bug Spray Kills Adults and Eggs, results below:
A laboratory bioassay was conducted to determine the efficacy of Best Yet as a direct spray insecticide against adult bed bugs and their eggs. Best yet was tested against both a susceptible, lab reared (“Harlan”) bed bug strain as well as a resistant, and field collected (“Trueth”) bed bug strain.
Adult Bed bug testing- Five replicates of 10 adult bed bugs were sprayed with approximately 1.0g of Best Yet from a vertical distance of 4-6 inches. Control bed bugs were sprayed with tap water. Immediately following application, the bed bugs were observed for knockdown at .5, 1, 2, 3, 4 and 5 minutes. The bed bugs were then transferred to clean containers and a final knockdown reading was taken at 15 minutes. Mortality was recorded at 24 hours post treatment. The results are summarized below:
Spraying bed bugs with best yet caused complete knockdown by 0.5 minutes post-treatment. Although slight recovery was observed at 1 minute post treatment with the susceptible bed bugs, all bed bugs treated with best yet remained knocked down at 15 minutes. At 24 hours, best yet tested provided 100% mortality of adult bed bugs.
Bed Bug egg testing – Five replicates of 10 bed bugs oviposited on filter paper were sprayed with approximately 1.0g of best yet from a vertical distance of 4-6 inches. Control bed bug eggs were sprayed with tap water. Immediately following application, the bed bug eggs were transferred to clean containers. Mortality was observed once a week for three weeks after treatment. The results are summarized below:
All control bed bugs eggs hatched by the first observation, 7 days post-treatment. Three weeks post-treatment, all eggs treated with Best Yet failed to hatch. These eggs were observed to be desiccated, suggesting that the formulation caused severe damage to the egg case, therefore preventing it from developing fully or hatching.
