I have both Quickfire and Pinky Winky and like them both, but both are large bushes. I can tell you that that the Quickfire along the sidewalk need to be moved or it will block the sidewalk. My Quickfire is probably 6'-7' x 6'-7', and Pinky Winky is about 8' tall x 12' wide. Both reached that size in about 5 years from transplants less than half the size of yours, so yours may put on at least a foot in all directions this year. If they were mine, I think I'd move them during the next stretch of rainy weather or in early fall. I can't tell measurements from the photo, but my inclination would be to move two of the three.

Here's a thread that shows my Pinky Winky's size development.

And here's a photo of Quickfire at full size. Sorry there's nothing in the photo for scale, but I'm 5' 5" and have to reach up to clip off old blooms from the top.

First, don't worry about the flies. It simply attracts them. Mine is always covered in flies, especially on sunny days. And not just one or two kinds, but EVERY kind of fly. It's kind of neat if you aren't creeped out by bugs. You won't have any trouble with pest damage unless it's eaten by tent worms (moth or butterfly larvae) or deer. And you won't see tentworms until there's silk because the eggs are laid along the stems and they're more or less too small to see.

Secondly, you could consider hard-pruning each year down to about 2' in height. That would prevent the plants from getting too large, and the individual blooms would be larger.

Or, if you dig them up, try to get a 2x2' root ball. If it's too heavy for you to lift, you could use a trash bag as a sled and drag it to the new location, or try to get a buddy to help team-lift it into a wheelbarrow or onto a cart.

your options are to give them a hard prune in late winter / early spring, that will keep them contained and encourage a good flower show.

It should not be too hard to transplant either. If you decide to do that just be careful not to damage the root ball when you dig them out. Also don't try to transplant in summer, it is too hot.

Fall is the best time for transplanting as plenty of sun, cooler temps and warm soil. Spring would also work for transplanting. Here in zone 5 if I transplant I do it around mid september.

Panics are known to attract flies, bees, etc. They have a faint scent in the blooms (some people can't smell it) that attracts insects for pollinating purposes and it makes placing panics near a front door a very bad idea, especially if you hate wasps. Anytime that the plants are dormant should be a good time to transplant, provided the soil is not cold enough to freeze or cold enough to make it tough on you. If you see that the leaves have browned out for maybe 2 weeks or so, I would assume that the shrubs are "asleep". Prepare the new holes before extracting the shrubs. Water the plants the night before extracting and try to move the plants without breaking the rootball (an extra pair of hands and old bedsheets can help with that). The root system should not be extensive but try not to harm the small roots in the top 4" where they get lots of water from. Once replanted, expect that it will fussy over the summer just as they were when originally planted. Keep an eye weekly during that summer.

Thanks everyone. I do think I will transplant 2 of them! For now I will just enjoy them, bugs and all. I live in ohio so maybe late sept or October I can transplant them.

Almost forgot, you CANNOT prune Quick Fire in Spring or it will barely bloom at all. Fall only. You can prune Pinky Winky in Spring, however.
