Flea & Tick
Collars
- There are better
alternatives now! -
|
Summary:
When first invented flea & tick collars
were a big advance in protecting pets from fleas and
ticks. Even today similar slow-release insecticides
are used for fly pest control in livestock. However,
there are now safer and more effective alternatives.

Flea collars developed in 1964
Flea & tick collars were
introduced in 1964 as an effective and relatively
safe way to protect dogs and cats from fleas
and ticks. Collars are made from a special
plastic that slowly releases insecticide
that kills adult fleas and ticks for weeks or even
months. After the specified interval the collars
should be replaced to renew the protection.
Prior to the widespread use of flea
& tick collars, infestations were a constant
irritant and health concern for pet owners. Over the
years there have been many different pesticides
incorporated into the plastic collars. Similar
slow-release technology is also widely used in cattle
tags for fly control.

Flea & tick collars work (for
ticks)
When they were introduced flea collars were
seen as an excellent solution to a severe problem.
They significantly reduced bites on animals that were
otherwise under constant attack. However, they had a
couple of problems.
Some animals develop an irritation in the
collar area called flea collar dermatitis and
the collars are really only effective on the front
half of the body, closest to where the collars
are worn. Because of this, flea and tick collars are
generally more effective protection against tick bites
because ticks often try to attach around
the head and neck. In fact, if you use a flea control
medication that does not control ticks, such as
Advantage (tm) or Program (tm), you should definitely
use a flea and tick collar if your pet spends much
time outdoors.

Better control methods
Much better and safer methods are now
available for flea and tick control. The best
methods control adult fleas and ticks with a
topically-applied medication combined with treatment
of the pet's environment with an insect growth
regulator called methoprene. Methoprene
prevents larval fleas from developing into adults
(see Flea and Tick Control
in Homes and on Pets for details).

Electronic/ultrasonic flea collars?
See our comments about electronic
pest control devices in general as the same
comments apply here as well (see Do
Electronic Pest Repellers Work?). The short
answer is: none of the devices that use
ultrasonic sound have worked in controlled trials.
