Just because you don’t see fleas on your pet doesn’t mean that you don’t have a flea problem! Many pets that have fleas don’t show signs of them. Don’t be fooled into complacency!

Our approach is to concentrate your flea control efforts on monthly prevention, using safe and highly effective oral and topical flea products like Nexguard® or Brevecto® in dogs, and Revolution® or Brevecto® for cats.

By being diligent with preventative flea control methods, you can avert environmental infestation thereby avoiding the use of environmental products which are much much more toxic to you and your pet.

Why should I use flea control when my pet doesn’t have fleas?

We recommend using safer products on a regular basis rather then toxic product after fleas have become a problem. Preventative flea control is much more effective and products like Nexgard ®, Brevecto, Revolution®, and Comfortis® are less toxic then environmental sprays and bombs necessary to treat existing infestations.

What diseases do fleas spread?

Fleas transmit the bacterium Bartonella, and Bubonic Plaque, all potentially transmittable to humans. Bartonella is the bacterium causing Cat Scratch Fever. It also has been implicated in causing a variety of other diseases in humans and pets. Bubonic Plaque has been reported in Arizona, California, New Mexico, Colorado, Utah, and Oregon causing illness in humans including several deaths.

Do fleas spread tapeworms?

Yes! If your pet has tapeworm, then it has fleas. You can identify tapeworm by seeing tapeworm segments on the stool or near the anus of your pet. We treat tapeworms with Drontal®, but you still need to treat your pets flea problem or reinfection will occur.

I’ve treated my pets for fleas but they still have fleas. Why?

With heavy environmental infestations, if you are not using monthly flea control, it is possible to still see fleas even after application of flea control products (especially the lower quality products). If your home is infested, you will need to treat the indoor environment. See “Treating Your Home” on the back of this handout.

Things to Know

Fleas spend 95% of their lifecycle off your pet. Your flea control program should control fleas on your pet to prevent infestation of your home.

REMEMBER: Since Fleas are found in Oregon year-round, use flea control year-round, even in the winter! Fleas spend 99% of their life cycle in your environment, especially carpet, NOT ON YOUR PET!

Once you have a flea problem in your house, you will have to treat it Fleas cause discomfort, weaken the immune system and transmit tape worms.

Treating Your Home


Vacuum well to remove flea dirt before spraying.


Spray home using 1 can of Siphotrol® Premise Plus II Spray per 2000 square feet. Concentrate on carpeted areas, making sure to spray closets, under furniture and especially under beds. Spray your pets bedding (wash bedding in hot water if possible.) Spray carpeted and upholstered area of the car your pet travels in.


Allow to dry completely, usually 1 to 2 hours, before re-entering the house.


Vacuum, daily for 5 days after spraying house to remove dead fleas and flea dirt.


Respray your house 2 weeks after the initial spraying to kill fleas which have emerged from cocoons. With heavy infestations, it may be necessary to spray several times.

Administer flea preventative to your pet monthly, YEAR ROUND! If you’re not seeing fleas on your pet, thats great, but don’t let your guard down.
•If you have an infestation of your home (which you can prevent by using monthly flea control on your pets), spray your home with SIPHOTROL® AREA TREATMENT SPRAY. Repeat in 2 weeks, vacuuming daily for five days after each application.

Flea Treatments to Avoid

Flea Collars: They’re a complete waste of money, and many contain chlorpyriphos, a pretty nasty chemical.

Organophosphate, carbamate, pyrethrin and permethrin shampoos, topical, and oral insecticide products:  These, too, are toxic and not even very effective. •Pet store and grocery flea products: Many of the earlier generation flea products sold over the counter are now flea resistant; some are toxic. •Garlic, brewers yeast and other naturopathic remedies: Unfortunately,Unfortunately, they don’t work. If they did, we’d recommend them!
