Are thripes a death sentence

Hi! I just moved into a new apartment in a new city, and tried to bring as many plants with me as I could. Today, after doing some investigations, I found a lot of my plants (mostly phillys) have thripes. Is this a death sentence? My mom mentioned a flea bomb in the bathroom with all the infected plants but I’m worried since I just moved into my building. I water when thirsty and repot as needed and have good light in my apartment . I also have very limited funds as far as treatments go

Any advice will help

Pictures are all my infected plants
