Trouble with Largemouths

[Capspath83]

Hey all,

So the past few days in a row I have been going out to my spot at my lake and throwing 4" -7" senkos like I have been since day 1 with catching some nice bass.

I cant seem to figure out why all of the sudden the bite stopped. I saw a nice 4lber by the dock and put the worm close to it, I saw it swim towards it and then move away. I am doing nothing different than I was doing in the past. The only thing that I can think of is the heat is turning them off even later in the day. I just bought some Perch colored jitterbug poppers and hula poppers to see if that may help, but wanted to get your opinion. Maybe a little topwater action would help, but I haven't seen anyone use poppers on this lake so I am not sure they will go for it.
