The neighbors in the duplex we live in had 2 dogs. They moved and the landlord is doing major inside renovation. The first few days much banging around, carpets, flooring torn up. Can the fleas travel over to our side. About three days after this our cat started scratching and found fleas all over. Is this possible?

We have lived here 20 years and have never had this problem, even with 3 cats.

Yes it is possible.

Hello r:

Fleas hate banging. For sure, that's what caused them to move.

Yes, fleas can be brought from net door. I would suspect pants legs as the vehicle.

Here's an answer I gave someone else that might help you out

Flea Biology 101 - Fleas pupate inside a cocoon just like a moth or butterfly. They do not leave that protected cocoon until it's time to get the blood meal they need to breed and lay eggs. Bombs, sprays, powders, etc. cannot penetrate those cocoons. You need to get the flea to hatch itself out so it can be affected by the pesticide.

Research has shown that there are three main factors in getting the adult flea to hatch out: temperature, humidity, and the vibration or pressure from a potential blood source passing by. As far as temperature and humidity go, guess who likes the same things we do? Yep.

Setting up vibrations in your carpets and rugs can best be accomplished by the beater brush on your vacuum cleaner. The vacuum also sucks up eggs, some of the larvae, and the dirt the larvae feed on.

To keep the ones you vacuum up from surviving, the flea powders for carpets help in a couple of ways: killing fleas and showing you spots that need more vaccuming.

Keep in mind that every couple of days more pupae inside their cocoons will reach maturity, so vaccuming once won't do. Fleas spend an average of two weeks in the pupal stage, so vaccuming daily for at least that long is essential.

Sorry about the book length answer, but if you know why you're doing something you can do it better.

Summary:

Keep the animal treated. With neighbor animals you MUST keep it up.
Treat the home with a product to kill adults and a growth regulator to inhibit maturation.
Sprinkle flea powder liberally on the floors after the spray/bomb has dried.
Vacuum, Vacuum, vacuum, vacuum, vacuum, vacuum, vacuum, vacuum, vacuum (14 times) every day for at least two weeks, maybe three.
