I HATE fleas.
Before California, I lived in places where summer was 4 months out of the year. The freeze that ensued for the other 8 months was capable of killing any sort of insect pest that became a bother. But California's round the clock temperate weather makes an ideal breeding ground for those little fuckers. Within my first two months of moving here, fleas replaced mosquitoes as my least favorite insect on the planet.
Enter Talulu. She's a 13 year old cat we adopted on a spur of the moment decision, and it was the best decision we ever made. But you know what fleas love? Cat fur. Once the hot weather hit, they moved into her fur and she's been miserable.
Most flea solutions are costly and deal with a bunch of chemicals that are no way pet friendly, which is why I was happy to hear about Diatomaceous earth.
Diatomaceous earth is a sediment made from diatoms, which are a kind of algae. It's a really fine powder, which you can get for pennies at bulk stores (Sam got us two cups of the stuff for $1!). It works by sapping out the water in the exoskeletons of fleas, killing them by dehydration. If that's too graphic for you, imagine trying to sleep with them crawling all over you.
What we've done is vacuumed, put the earth down, waited 12 hours, and then did the whole thing again. You can even put the earth on pets! We put it on Talulu once a week, any more than that dries your pet's skin out.
So hell yeah, thank you diatomaceous earth!
