If it's a cartridge type BB, remove it/have it removed and add some new lube to the threads of the BB and the frame threads.

That is an area of the bike sees a lot of grit and abuse. Lube it and see if it continues.

Does it creak when pressured from either side? When this happened to me, drive side only, I was advised to tighten the crank bolt. I did, and the problem disappeared. FWIW.
Probably just needs to be tightened a bit...Quack

I've seen many different recommendations as to the remedy for a creaking bottom bracket and have actually tried all of them to test out the theories. From all that I have learned, when your bottom bracket creaks and it is well lubed, there is play between the spindle and the bearings. By tightening the cups slightly, you can take the extra play out and prevent the spindle from walking as you apply pressure to the crankarms. I used to tighten BBs so that they spun easily by hand to minimize resistance, and always ended up with creaks inside of 100 miles. Once I started tightening them until they offered resistance when turned by hand, no more creaks. Bearings and spindles are tough. And the resistance felt in your fingers will be undetectable to your legs. But you can teflon tape threads and lube parts and hope for the best, maybe it'll work. Make it tight and it should be trouble free until water washes the lube away.

Good Luck!
