A Flea infestation typically requires a multi-pronged approach to successfully treat. Treating house, treating grounds, treating pets, etc. (Ok, no pets here.)

You should pose your question to the pet company and also ask them what areas they treated.

Based on the contents you posted above, you will not get a definitive answer here.

I have heard about this, might be easier and cheaper:

So much for the required multi-pronged approach. lol

Just an FYI...use regular table salt, the generic will do. Sprinkle it all over the floors, carpet, etc. Will kill fleas in 2-3 days. Vacuum up. Crazy cheap, salt is $0.48 for a large container. Takes a cpl containers per 1,000sq ft.

I know it’s a rental and miles away, but just wanted to pass on the suggestion for future reference. I had a ton of squirrels in my yard at my last house, couple times a year fleas would hitch a ride on my pants leg into the house. I had no pets and keep an immaculate home. I assumed the squirrels had fleas...every time I stepped in the yard I would get bit by fleas. Drove me nuts. Salt works very well and quickly.

Table salt might dessicate them? I can’t imagine the amount you would need and the level of cleanup required after...

As usual, I’m with SaltiDawg. But as it’s a vacation house and often vacant, it might not be quite that bad....

Regular iodized table salt. For 1,000sq ft area I’ve used 2 of the large containers. They’re less than a buck a piece. Cheap, works, and non toxic. Can live in the house while killing fleas. I know it sounds crazy, but it works. Clean up takes 10 minutes to vacuum up. Just sprinkle on the carpet. It does take about 48 hrs.

H2O2 would work on fleas too......

As would neuter-spay. Very small instruments.
