I can't see them very well but I don't think they are eggs.

Pick up one and smash it with a spoon. If it cracks, it's eggs.

IF it is eggs it could be any kind of insect that has got into the house and laid its eggs. Shouldn't harm the violet, but scoop them out with a spoon.

I sprayed top of soil with insectiside "Safe Garden" and I'll hope it help.
Thanks.

Can't see enough detail to know if they're eggs.

But I wonder if you have the water-absorbing crystals in your potting mix? If so, that may be what it is.

Sometimes fertilizer build up will produce a white/grayish area. Spraying was good, but remove that area for sure. It's probably going to be fine. tish
