| Flea infestation. What to do?
This is driving me - and my pets - crazy.
When we moved in there were fleas. We treated the cats and got rid of most of them, but not all of them. After getting the dog, they got worse. Partially because she goes outside and that's where they're coming from.
I have the inkling that all the places where we are are infested. It was horrible when we first moved in and the cats were flea free before then. It's been a losing battle. Now that it's warm, they're multiplying rapidly.
We've been using diatomaceous earth on the pets, under coushions, on the floors and outside, and it works for a bit, then a few days later they multiple even worse. We've also started flea combing everryone.
We're trying to avoid chemicals, partially due to cost (money is extremely tight this month, though should be much better next month when I get a job) and due to the older two cats. They've had reactions to vet flea meds before and with their age I don't want to risk it. One hasn't been at 100% health as of late, possibly due to the fleas or due to her age, so I don't want to use anything on her that could make it worse. It's mostly just a bit of energy loss; she's still eating, just sleeping more than usual.
So my question is.. what can we do? Should we give in and just use chemicals on them and watch them real close? Should we try something else natural? Are we doing something wrong with the earth stuff?
i'm at a complete loss. I've never dealt with an infestation this bad before, and we've had some pretty nasty flea problems in the past. I know there's mice, rats, raccoons and an outside cat that all have fleas (and the cat has worms, another thing we have to treat our pets for now -_-) that hang around outside. Dandi's awful when she comes back inside from walks or potty time.
At this point I'm tempted to just move when we have the money. But I don't know when that's going to be an option. |
