Developing floral-based replacement molecules might manage blood-sucking vectors in an eco-friendly way. ( ) aqueous leaf extract (ALE) and silver nanoparticles (AgNPs) were evaluated against mosquitoes ( , and ) and ticks ( , and ) at different concentrations. Phytochemical screening and AgNPs’ synthesis were performed on ALE of . UV-visible spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscope, and transmission electron microscope were used to examine the synthesized -AgNPs. ALE included alkaloids, flavonoids, saponins, tannins, triterpenes, coumarins, anthraquinones, and phenolics. -AgNPs had a higher LC (22.19, 23.92, 26.09, 40.25, 51.87, and 60.53 μg·mL , respectively) than leaf aqueous extract (LAE) against , and larvae. ALE and -AgNPs’ bio-toxicity was investigated against aquatic and terrestrial non-target species ( , and ) with LC values ranging from 2,094.5 to 10,532.8 μg·mL , respectively. ALE and -AgNPs had little negative impacts on the chosen non-target fauna. Environmental protection is important nowadays. Green AgNPs are low-cost, readily accessible, environmentally safe, and effective pesticides. Am-AgNPs are effective alternative insecticides, requiring a considerable study on this plant to control blood-sucking vectors for worldwide human/animal health importance.
