I have 2 evergreen bushes near a patio door. I walked past them today and hundreds of flies flew out from the bushes and returned back into the bushes when I walked away. What can I do to get rid of the flies? The area with the bushes if very dry and under eaves of my roof.

Hi Michelle, We see many insect swarms this time of year. they generally last a couple weeks then disperse so no control is necessary. Sandy
