I feel for you I had a run in with those little SOB's I have inquired about the same thing that you are and have got no real answers to my question. What I am going to do this year is rototill early and put clear plastic over the whole garden and see if I can bake the pupae and hopefully it will kill all of them. here is part of one of the articles that i found it will kind of give you an idea of how they work. Life History - Pepper maggots overwinter as pupae 5 to 10 cm below the soil surface. Flies emerge from late June through August and mate. Soon afterwards, females insert eggs just beneath the skin of young peppers. Eggs hatch about 10 days later depending on the growth rate of host peppers. At this time the peppers are usually 2/3 to fully grown. Larvae feed within the peppers for about 18 days. When fully grown, each larva cuts an exit hole, emerges, and drops to the soil to pupate. Only one generation occurs each year. Dale

I remember reading a short story in college (a long time ago...) that said the only way to avoid chigger bites was to run through the field naked. Idk, haven't done it, but they love me. I may be the only one out of 3 or 4 people in the exact same area who ends up with bites. I have found only one spray that kept them off of me and I let a friend use it for her freaking mosquitoes. I don't know why mosquitoes don't really like me, but chiggers LOVE me. Is there any known reason why some people are more likely to get chiggers VS mosquitoes? Or, am I the only fortunate one? One thing that a friend of mine swears by, and he mows lawns for his employment, is sticking dryer sheets in his socks. He looks odd, but he says he gets no chigger bites by doing this. I don't trust it, but anyone else had luck with this? Or even hearts of it?

We've got bad chiggers in central TX, they're unavoidable, we get them just walking in any type of grass in our yard. Since you just cant jump in the shower 5 times a day to wash them off, instead I find that I can whisk them off with a medium-soft bristle brush. I get a big brush and take off my shoes and socks, then brush the feet good as (if they were covered with ants), turning the socks inside out to brush hard there as well. Then pull up the pant leg and brush behind the knee... you know they like it there! (groan) If you got privacy go ahead and do the rest of their favorite locations. Brush well! It takes a minute, but its worked somewhat for me, my legs have fared better lately. chemical free - energy free Its hard to avoid getting bit up by chiggers if I have to cut weeds with the gas trimmer, even with DEET. They are nasty. I see people stopped along side the highway taking wildflower pictures in late April, and just shudder. Get ready to itch!

Concrete topping over wood joists is quite normal in Canada in low-rise buildings. We see this quite frequently. The fix: everything vs. nothing. As you have guessed, the issue is UNDERNEATH the concrete. And to get at THAT layer your upstairs neighbors have to remove everything, jack out the concrete and then "fix" whatever needs fixing (sigh....guess how many times that's going to happen? Zero). And because the problem is your problem (it bothers you, not them) you will have to spend all the time/money investigating this issue. It is *possible you can rip down your ceiling (yep....throughout the ENTIRE condo) and investigate the problem from BELOW. I'm going to guess this isn't going to happen either (cost is going to be WELL over $15-$20/sf to remove, repair and replace ceiling). The fix that you could attempt without having to investigate the actual source would be to have a drop down acoustic ceiling installed with proper isolation channels and acoustic drywall/ceiling tiles. It is possible to do this for about $10/sf. If you have UNTEXTURED ceilings, it is *possible you can use GreenGlue+Acoustic drywall to create an acoustic barrier that will offer another 36 dB of insulation (5/8" acoustic drywall = 18 dB of insulation; GreenGlue sandwiched between the old ceiling and the acoustic drywall = 18 dB of insulation). This can be done for about $7/sf and will not lose ceiling height. My personal favourite is a "white noise" machine for the bedroom. The simplest option = fan. $15 from Home Depot. And no I am not being facetious. I am offer a cheap, simple (and often effective) solution to a sleep problem. White noise machines will do a tremendous amount for your sleep. Once you get a few months of decent sleep (yes...it takes that long to pay off sleep debt), you will begin to feel better about where you are. And eventually, if everything goes well, you will stop hearing the noises from above. All for $15. This would be my first stop. You can always add more materials to your ceiling and remove money from your bank account if the $15 fan doesn't work.
