Will rain after an application of Bifen XTS reduce the effectiveness of the product?
I applied it to my yard. About 45 minutes after I finished the application, it rained(moderate to light) for about an hour. Also, how long does it take to see results. I have a flea problem, and I am trying to eliminate them.
Typically, Bifen XTS as well as many other liquid insecticides only need about 30 minutes to dry. Once dry, they can hold up to rain rather well. However, it is much easier for the product to bond to porous surfaces like concrete and siding then grass and your lawn. You may want to apply again just to be safe when there is not rain in the forecast for at least 24 hours. Typically, for fleas it can take a week or two to see results. You should treat every 14 days for fleas. It usually takes at least 2 to 3 treatments since Bifen XTS or any other product will kill the eggs. You need to treat every 14 days, 2 to 3 times, so you make sure the product is strong enough to kill the hatched eggs every 2 weeks.
