Battling Super Fleas

Back ground – Rent a house in March 2018 – found out after we moved in that previous rents walked away from place and left 3 dogs – 2 cats and a lizard in place for a month – ( lizard died & I buried it ) but when the super hot spell hit at the end of June 2018 – high temps & humidity – fleas came to life big time – I have used a container & 1/2 of salt – 9 cans of Raid – 4 cans of fogger from HOT SHOT ( was useless ) – 2 1/2 gallons of Vinegar & soaked the place and still have fleas – think they all have big red “S”s their chests – HELP!
I’ve also vacuumed the crap out of the place several times – burnt the contents also – UGH.
