Spiders are not very tolerated by most people, period. They scare people,
some types of spiders can bite, they leave messy webs and some people
have a phobia - a deeper than normal fear of the little eight legged creatures.
Spiders feed two ways. They hunt down their prey (other insects), or create
a web to catch the prey while they wait. A live spider that uses a web,
will keep the web clean and in good repair. If the spider has abandoned
the web, the web will build up dust and become more visible and eventually
start falling and looking bad.
Spiders migrate (travel) by crawling, hatching or
Ballooning is when the spiders (usually babies) hatch from a nest, let out a web
and the wind current or breeze carries them until they basically "hit
a house" or tree, or fence, or just land. During the windy times
of year, spiders really move around and that's when we get most of
our spider service calls.
A spider nest can hold up to several hundred eggs. The baby spider is very
tiny but grows quite quickly. If the nest has hatched inside your home,
within a week or two the babies become bigger and more easily noticed
- but there seems to be a lot of them. Sometimes they are a generation
of brothers and sisters.
Occasionally spiders may bite. A spider bite is normally determined by
your doctor. Some people do not tolerate spider bites very well. The main
difference between spider bites and bites from fleas, mosquitoes and most
mites is that spider bites will normally feel more
sore than itchy.
A spider has a stomach enzyme that gets into the wound upon the bite. This
enzyme is designed to break down the tissue. In an insect, the spider
cannot chew up its prey, it will bite the prey and the enzyme will break
down the insect to a fluid and then the spider can drink the dissolved insect.
We have had reports from some customers that the bite has caused a serious
infection including staph infection. It is very important that if a suspected
bite becomes inflamed, painful and/or is not healing normally or you develop
symptoms like fever, a red line going up your arm or other area where
the bite occurred, you need to get a diagnosis and treatment from a qualified doctor.
Black Widow Spiders
Black Widow, Brown Recluse and Yellow Sack Spider are examples of spiders
that can be very dangerous if you get bitten. Fortunately the Brown Recluse
and Yellow Sack Spiders are not common to the Santa Clara Valley and if
these spiders or bites are suspected then usually the bite occurred while
traveling or were shipped or transported in somehow. If bites from any
of these spiders occur, immediate medical attention is necessary.
Black Widow however, is very common to the Santa Clara Valley. The good news is that
they can be easily treated and controlled. The Black Widow is a unique
looking spider. The female is black with a shiny, round, hard looking
body with a red marking on the underside of the belly (mostly described
as an hour glass). The Black Widow is very shy. She likes cellar-like
environments such as garages, basements, sub areas and dark damp places
like wood piles, and any other stacked debris that stays relatively dark,
quiet and undisturbed.
The Black Widow is a nocturnal spider that primarily hunts at night. The
Web is sturdier than other spider webs and feels very elastic. The web
pattern is also irregular in appearance. The egg sack from a black widow
is also unique. The egg sack is white and round like a cotton ball and
could be the size of a marble or up to the size of a golf ball. The female
Black Widow can deposit approximately 300 eggs. The male and female Black
Widows all look the same when babies. The babies have a spotted appearance
and as they grow, they molt. Molting is a process where as an insect grows,
they need to shed their skin periodically as they outgrow it. As the Black
Widow babies develop, the male becomes a wimpy smaller spider and the
females take on the unique appearance described earlier. The female is
also known to kill the male after mating.
The Black Widow is not normally aggressive, but will become defensive if
she or her egg sack is threatened. Do not poke at or handle Black Widows
or her egg sack. Most of the time the Black Widow will stay hidden and
quiet, they are very reclusive.
What does Bay-Valley do?
It is important to treat the surfaces spiders are likely to roam and crawl
on. Generally this is under the eaves, around window and door frames,
ceiling corners, and other possible areas inside and outside the home.
It is our job to determine these areas and treat effectively and routinely
(at least once every two months, Bi-Monthly). It is also our job to pick
a product that works on spiders.
By treating areas that spiders roam we are able to keep the spiders down
to a tolerable level. Certain products work extremely well and others
really won't do anything. Knowing the products that work and where
to apply them is everything in spider control.
