Spiders, belonging to the class known as Arachnida, are highly evolved with over 45,000 known species and a few more thousands are yet to be discovered. They are found in almost every part of the world except in Antarctica. They are air-breathing arthropods with eight legs and their body is divided into two, the front portion is known as the cephalothorax and hind part is the opisthosoma. They usually possess fangs which they use to inject venom while hunting for prey rather than for self-defence. Most spider bites are not dangerous to humans except that of the Black Widow and Brown Recluse. These are deadly and if not treated with an antidote on time, could lead to fatality.
Spiders can be divided into two groups depending on how they capture their prey. Hunting spiders do not construct webs to capture food. Instead, they rely on quickness and relatively good eyesight to chase and capture the prey. Active hunters (sometimes known as wandering spiders) actively search for and chase their prey. Passive hunters lie in wait and seize the prey as it approaches. Hunting spiders live outdoors, but may wander into homes accidentally, particularly in the fall, but they do not survive well and usually do not reproduce indoors. Web-building spiders construct webs in calm, undisturbed places to capture their prey. They live in or near their web and wait for the prey come to them. They generally have poor eyesight and rely on sensing vibrations in their web to detect the prey.
1. The injection of salivary fluid or venom into the skin provokes a small, itchy swelling that lasts a few hours or days. 2. Bites are seldom fatal: infants, the elderly, and people with allergies are at greatest risk. The bite itself can pass unnoticed, but within hours, intense pain and stiffness may begin, occasionally followed by muscle spasms, abdominal pain, chills, fever and difficulty in swallowing or breathing. 3. The Black Widow Spider is one of the most venomous spider species and its bite can cause serious spasms which may require immediate medical treatment. 4. Spider mites damage vegetation, flowers and ornamental plants. The mites appear as yellow or brown spots on the leaves of plants. If untreated, the plant may turn yellow which may affect its growth. 5. Spider webs often lead to interiors looking dirty and they could also decolour paint. Spider webs are a concern when it comes to the upkeep of interiors, furniture and places less visited like cellars, basements, garages and attics.
Chemical will be sprayed under siding, cracks and crevices and on the temporarily created webs. No object will be disturbed.
All the spiders will die.
