Mom was a cleaning fanatic and swore by her Electrolux canister vacuums. 

Use a high quality HEPA vacuum and empty the bag/canister immediately after and then spray down the vacuum and nozzle with a flea killer spray you can buy at Walgreens.

Exterminators were brought in to set off gas canisters during which they had to move out for a few days and in the end they even replaced the expensive wool carpeting.

You will have a local seller of pest control products, which is where the pest control guy gets his stuff from.Buy one of those plastic canisters that you pressurize (can't remember what they are called), some good old Cyper WP or Permethrin, and have at it.

Many come with their own little collection baggy or canister, but they fill quickly and still don't do nearly as good a job as the powerful suction from a shop vacuum.

what stockade fence, we will call them sticks.This is what I did over the 3 months What was removed and replaced withRemoved the drop down ceiling in kitchen and installed canister lights.

Mold was so bad I had to wear a canister mask in the basement.

It likely means setting off a few of those canisters of "bug bombs" you can find at most Big Box stores.

IMPORTANT: I would stage the house with color in the kitchen & baths, (flowers, canisters, some nicely done drapes or blinds, etc) We stage our properties and we spend less than $500 - there are plenty of inexpensive materials to use for accents that don't cost much. 

Geocaching is a GPS treasure hunt hobby where you find items (from ammo boxes to film canisters, always with a log, sometimes with loot to exchange) hidden based on coordinates and clues.
