I'm posting this here bc you guys have never failed me and I [my daughter] has a huge problem....
My daughter and her 3 roommates [all 1 yr just out of college] have rented an older pier & beam home that had an addition w a solid foundation to make it 4 bedrooms. Because the crawl-space to the pier & beam was not secured, an animal entered and climbed up into the walls of my daughters bathroom closet. She heard it scratching in the walls so she reported it to the landlord.
It was discovered that there was a sm water leak in the wall and the animal was seeking both water and prob shelter. This was the during a drought in austin tx this summer, w 30 days of straight 100+ temps and no rain. Once the wall was opened, the leak was found and fixed. The repair person said to leave the wall open until it dried out. This is when a massive flea infestation took place. If you went into the house, your white socks turned black in a matter of seconds.
I called their landlord and told him the house was uninhabitable and you needed to find a place for them to stay. He begrudgingly ok'ed a rented an ABnB for a week, whicg turned to 3 weeks and 3 diff places. An extermination company came and did 2 diff flea treatments 2 wks apart. After spraying/laying powders, using growth reg hormones, inside and out. Then 2 weeks later, the fleas were still there. My daughter and her roommates came 2-4 times per day to vacuum up any and all eggs, larvae, etc. I am going to skip forward bc this would take too long. They collectively logged over 130 hrs of vacuuming.
After hiring another company bc the first one did not cut it, 82 days later my daughter found another flea on the flea trap in her room. She has not been able to sleep in her room in over 3+ months. The handyman, when trying to work on closing crawlspace and other, was bitten countless times on his back, neck, legs, etc. My daughter had to buy a hazmat suit to go inside the house to vacuum each time, they all did, She's spent over $600 on supplies, recleaning her things, which are all in black plastic bags. This is the second time of cleaning.
In order not to make this a novel, I am seeking advice for anyone that has experienced a really bad flea infestation, what you did to rectify? More so if you were in a rental house or a pier & beam house. It's really taken a toll on her especially, bc her room has had the most and continued issues. Pls let me know what questions you have and sorry for the long post. I thank you in earnest for any & all advice...nothing is more personal than when it comes to your immediate family. thank you very much.
