(Rhipicephalus
sanguineus)
The Brown dog tick Is
associated with domestic dogs, their kennels, runs, and houses. When ticks
are not on a dog, they hide in cracks and crevices, often in great numbers.
In the United States, brown dog ticks rarely bite people. However, houses
with brown dog tick infestations may become overrun with them. It is most
numerous in the southern and southwestern states and in California. The
brown dog tick is a hard tick that spends all its life cycle in and near
the living quarters of its host. Engorged females drop off and crawl into
cracks and crevices to lay eggs. Larvae and nymphs also hide in such places
and come out only when ready to feed. Dog kennels, runs,and houses may
shelter hundreds of hiding ticks.
Adult males are reddish-brown,
1/12 to 1/8 inch long. Adult unengorged females resemble males. Engorged
adult females may be 1/4 to 3/8 inch long. Females have gray-blue to olive
bodies. The nymphs resemble adult females, but are smaller. The larvae
resemble small nymphs, but have six legs. The eggs, laid in groups of thousands,
show a whitish spot just before hatching, but are smooth, shiny dark brown,
otherwise. After laying eggs, the shriveled female dies.
Under ideal conditions the life cycle may be completed in about two months,
however, under normal conditions, with a host present, there are usually
3 to 4 generations per year. Because larval and nymphal stages can live
two months without feeding, and adults can live at least eight months with
no host, infestations can persist long after dogs leave the premises.
The brown dog tick seldom attacks animals other than dogs.
The brown dog tick is not known to transmit diseases to humans but may transmit disease among dogs.
Control:
Successful brown
dog tick control requires a three step program consisting of:
(1)
sanitation,(2) treatment of premises, and (3)
treatment of the dog.
The infested home
or kennel should be thoroughly cleaned to eliminate as many of the ticks
as possible. Pet bedding and resting areas should be given special attention.
The infested dog should be treated by a veterinarian on the same day
that
the premises are being treated. The premises occupied by the dog can then
be treated with residual sprays or dusts. Remember, these ticks like
to reside in the upper portions of structures and in cracks and crevices.
Several
pesticides are labeled for tick control.

What
are a ticks natural enemies if any?
Ticks
have many natural predators in the environment. Several wasp species will
parasitize ticks, one species in particular (Ixodiphagus hookeri) has been
studied quite extensively. The female wasp lays her eggs inside an engorged
nymph. After the wasp eggs hatch, the larvae feed on the tick's internal
tissues and then emerge, killing the tick in the process. Many species
of spiders will also eat ticks if they can find them. Also, there are a
variety of fungi and nematodes that also feed on and kill ticks while they
are molting in the soil. Birds will certainly eat ticks that they encounter
during foraging.
