Information on Fleas and Flea Control for your Pets

No Description

- Fleas thrive in 80 degree F temperatures and 80% humidity!  Temperatures less than 65 degrees F and humidity less than 70% will slow their growth.

- The average lifespan of a flea is 2 to 3 months.

- If you see a flea on your pet, it may have come from eggs that were laid 3 to 8 weeks ago!  This can be a reason why you see fleas for a few weeks even if you have started optimum flea control.

- Fleas can lay up to 50 eggs per day.  A female flea may lay 2000 eggs in her lifetime!  These eggs drop off into the house and yard and will hatch weeks to months later. The fleas must jump onto the animal before most products work.

No DescriptionFor Effective Flea Control

- If ONE pet in the household has fleas then ALL pets in the household must be treated.

- Use flea control ALL YEAR ROUND to prevent resistance to products and to maintain a flea free pet!

- Use a flea product with an adulticide and a growth regulator to kill both the adults and the eggs/larvae.

- If you see flea "dirt", your pet has fleas!!! (Picture to right shows flea droppings commonly called "flea dirt".)

- Treat the yard as well!

Flea Product Helpful Hints
- Apply topical products to the skin - not on top of the haircoat.

- Do not split doses between pets - you cannot be sure you are applying the correct amount to each pet.

- BE CAREFUL WITH CATS!  DO NOT apply a product that says "DOGS ONLY" onto a cat. If you have a dog and a cat be sure the product labeled for the dog is safe for the cat as the cat may contact the product by laying with the dog and this could cause toxicity (or even death) with some products.

- You may decrease some products efficacy if you bath the animal frequently of if the dog swims frequently.

- Don't forget to apply the product once a month for optimum flea control.

- Even if your animal does not appear to have any fleas, it may have a flea allergy!  Some of the most sensitive animals that are allergic to fleas will have severe reactions in the skin from 1 flea bite!

What Flea Products Do I Use?????

Flea Collar = INEFFECTIVE. 
     The flea collar does not offer enough coverage to kill or repel fleas. It can cause hair loss or allergic reactions in some pets.

     A flea bath just kills the adult fleas on the pet and has minimal residual activity. To be effective, you would have to bath the pet every 1 to 2 days (and then deal with the dry skin!).  Adult fleas are only 1 to 5% of the total flea population so if you are just using a flea bath as control, you are only treating 1 to 5% of the problem!

Flea Spray (not including frontline spray) = INEFFECTIVE
     Short lasting, mainly kills adults, requires frequent application

Over the Counter Permethrin Products =  INEFFECTIVE
     These old products are not very effective because of documented resistance of the fleas to these products. The are often not waterproof and many only last 2 weeks compared to the suggested 4 weeks.  These products can cause severe toxicity and death in cats (read the labels!).
