How Poisonous are Spiders in Indiana?
All types (except Uloboridae) are poisonous!
The Brown "Recluse" spider is not aggressive, bites from
this spider are rare. This spider only normally bits a
person when it is press up against the skin, for
instance, when tangled up within someone's clothing,
bath towel or in bedding. If bitten, most bites are
minor with no necrosis (necrosis is the premature death
of cells and living tissue), however, in a few cases
bites produce severe dermonecrotic lesions and sometimes, severe
systemic symptoms. In very bad cases, this can lead to
organ damage and death. For a fatality to occur, the
person may have a week immune system or children under 7
A few species of Brown Recluse spider bites form a
necrotizing ulcer that destroys soft tissue that can
take months to heal and also leave deep scares.
If bitten, an ice pack is to be applied to help control
inflammation, with the application of Aloe Vera to help
soothe and control the pain, also prompt medical care
should be sort after. If the spider can be captured, it
is best to bring it with the patient for identification.
The Northern Black Widow
spiders are very tiny but their venom in comparison is
extremely potent, compared to other spiders, the black
widows mouth is not very big and powerful, in the case
of a female, the fang that penetrates the skin is only
approximately 1 millimetre long, long enough for the
venom to be injected where it can do harm, the males
being smaller injects less venom doing less harm, in
physical volume the amount of venom injected by a mature
female is very small. When a mature healthy
human is bitten by a back widow
spider, the small amount of venom is
diffused thought the body and amounts muscle aches, nausea and
paralysis of the diaphragm. In the United states
between 1950 and 1959, only 63 deaths were reported
as a result from a Black widow spider. Black Widows
are not aggressive and will only bite if you were to
site on them for instance.

made by animals or around construction openings and
piles of wood, in the home they like the same kind of

entangled on their web or to worn them of something
larger such as animals that could injure or kill them
Classification of Poisonous Spiders in Indiana
Species of spiders are classified according to shared
physical characteristics. Spider taxonomy is the science
of finding, describing, classifying and naming organisms
in a hierarchical system. This method of classification
helps when a description of 40,000 spiders is required!
The organization of living things have seven major
categories: Kingdom, Phylum, Class, Order, Family,
Genus, Species. The classification of Poisonous Spiders
in Indiana are as follows:
(Kingdom relates to the highest taxonomic group into
which organisms are grouped; one of five biological
categories: Monera or Protoctista or Plantae or Fungi or
(Phyla are groups of classes. A series of animals or
plants genetically connected with shared
characteristics. The second biggest grouping in
taxonomy. Arthropoda are jointed-foot invertebrates:
arachnids, crustaceans, insects etc
A Class are taxonomic group
containing one or more orders. Arachnid consist of
any of the eight-legged creatures, including spiders and
scorpions, of the class Arachnida
A taxonomic order, within the class Arachnida (spiders)
The Subclass is nother taxonomic category below a class
and above an order which helps in the classification
Family: Brown Recluse:
Northern Black Widow: Theridiidae
Another taxonomic category below an order and above a
genus which helps in the classification process.
Genus: Brown Recluse:
Northern Black Widow: Latrodectus
Another taxonomic category below a family and above
the level of species which helps in the classification
Species: Brown Recluse:
Northern Black Widow: L. hasselti
Specis are taxonomic group whose members can interbreed.
Spider Exterminators - Pest Control
Generally speaking, people do not like spiders and most
of all, do not want them in their homes! There are many

There are spider exterminators, services, spider
zappers, spider traps, spider repeller, spider catchers,
spider traps for the removal and extermination process.

pest prevention, spider catchers, spider exterminators
and how to kill spiders. Some people would like to
eliminate spiders from there homes completely, this can

will allow spiders in, even opening your front door when
entering and leaving will allow pesky spiders in. It is

yourself. Its best not to kill spiders as they are very
important in controlling the level of other insects that
