Fleas on your pets
1) put 3 drops of pennyroyal on a nylon collar. This idea may be too strong for some cats. Pennyroyal should not be put directly on cats. Reports indicate that this technique works well even during heavy outbreaks.
2) There’s a new spinosad pill for pets that appears to be quite effective. It is called Comfortis
Spinosad has been formulated into two commercial products registered for use in commercial agriculture, including DowAgros' Conserve SC, and Entrust. Entrust is approved for use on USDA certified organic produce.
There are several home garden product manufactured for use in the United States including Monterey Garden Insect Spray manufactured by Lawn and Garden Products, Inc. and 'Borer, Bagworm, Tent Caterpillar & Leafminer Spray' manufactured by Ferti-Lome. Bonide Products has introduced spinosad in its Captain Jacks Dead Bug Brew insect control product line.
The products have practically no odor. Its soil absorption is moderately strong and it degrades rapidly in the environment primarily through photolysis.
Spinosad is also the active ingredient in Comfortis, a chewable flea medication for pets
It is acceptable in the organic program. It was developed from a living organism, has little to no toxicity and seems to work well. It is for sure better than diazinon, Dursban, orthene and the synthetic pyrethroids.
