Ticks are blood-sucking ectoparasites of mammals, birds
There are 2 types of ticks, hard and soft. Hard ticks have only one nymphal
stage while soft ticks have more than one. Some have up to eight.
They have eight legs like the spider.
They are most common in spring and late summer.
They are found commonly in transitional areas between woods and meadows or cut
and uncut grasses.
They are related to mites.
They have a complete life cycle, usually mate on the host animal and the hard
tick male dies after mating with female. Eggs are usually laid in cracks or
The most common tick to our area is the American Dog Tick. They lay 4000 to 6500
eggs usually in June or July which then take 36 to 57 days to hatch.
Larvae and nymphs feed on small rodents and even
lizards. Adults seek larger mammalian hosts such as humans, sheep, cattle, dogs,
The larva is capable of laying in wait for up to 8 months without feeding, while
adults can go 1 to 1/2 years without food.
Blood is their main meal and both males and females feed only on the blood of
Ticks can be classified by their feeding requirements. There are single host
ticks, two host ticks, three host ticks, and multi-host ticks.
Most hard ticks are three host ticks in which each of the three life stages
leaves the host after engorging.
Most soft ticks are multi-host ticks.
Ticks sit on foliage or branches and wait for a host to happen by, then they
attach themselves to the host for a blood meal.
VECTORS OF DISEASE
Ticks surpass all of the Arthropods in the number and
variety of diseases which they transmit to domestic animals. And only mosquitoes
transmit more diseases to humans.
Some of the diseases vectored by ticks include Colorado Tick Fever, Rocky
Mountain Spotted Fever, Lyme Disease, Powassan encephalitis, Relapsing Fever,
Endemic Typhus and many others.
Ticks are also transmitters of a disease called tick paralysis. A toxin from the
ovaries of the tick is transmitted to the victim as long as the tick is
engorging. Symptoms include a progressive paralysis from the legs upward and can
result in death for humans if the tick is not discovered and removed.
Most infestations of ticks can be controlled with the
regular Pest-A-Way Barrier (yard spray) in conjunction with the treatment of any
