In household concentrations pyrethroids are generally harmless to humans. [1] However, pyrethroids are toxic to insects such as bees, dragonflies, mayflies, gadflies, and some other invertebrates, including those that constitute the base of aquatic and terrestrial food webs. [2] Pyrethroids are toxic to aquatic organisms, especially fish. [3]
Fipronil (IUPAC name 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-(trifluoromethylsulfinyl)pyrazole-3-carbonitrile [1]) is a white, solid powder with a moldy odor. It is degraded slightly by sunlight, stable at normal temperatures for one year, and is not stable in presence of metal ions .
The risk of killing bees and other beneficial insects is partially reduced by the compound's rapid breakdown (a half-life of approximately 12 hours on plants and on the surface of the soil, with about 3% remaining after five days, but persisting several weeks or more if it enters a body of water or is dug into the soil) and its slight insect ...
I just found out I’m allergic to them last summer. Answer: The majority of native bees are solitary and ground nesting. They are docile, rarely sting and are important pollinators.
Cypermethrin is a broad-spectrum insecticide, which means it kills beneficial insects as well as the targeted insects. [14] Fish are particularly susceptible to cypermethrin, [ 15 ] [ 16 ] but when used as directed, application around residential sites poses little risk to aquatic life. [ 17 ]
You’re not imagining things — bugs, including ones that bite, are more active in the summer. Here’s how to identify bug bites, treat them and keep bugs away.
