Fleas and ticks can be a year round problem here in the deep South as temperatures don’t get low enough for a long enough period of time to slow them down.
So just finding a few fleas on your pet is not an indication that you’re needing your home and yard treated.
The rule of thumb is… if fleas are jumping on you and not just on your pet, then you need to have your home and yard treated. A simple way to check to see if you’re needing a treatment is to wear white knee socks and walk around your yard, periodically checking to see if fleas are jumping on the socks. They are attracted to bright colors and movement, so this is an easy way to check both inside your home and the yard as well.
