The Hobo spider, also called TegenariaAgretis, is among genus Tegenaria and is closely related to Tegenaria gigantean (house spider). This spider is quite large. The females have the ability to reach the maximum length of the body of 20mm and a span of legs of up to 50mm. even though the males are smaller with the maximum length of body of 12mm, they have the capability to get an impressive leg span of 80mm. Naturally, you can find them in Europe, and they got introduced in the United States in 1930s. It was first seen in Seattle and spread from there rapidly. The rapid spread is as a result of absence of this natural enemy, giant house spider.
These spiders are not as aggressive as others. The conjoint name ‘aggressive spider’ seems misinterpreted as per the original Latin name. According to English, Agretis means from the fields but not aggressive; unlike in the US, this name suggests that there are a few hobo spider in European houses. The main reason for this aspect is that its competitor, giant house spider, is a common creature there. The more house spiders, the less the hobo spiders will inhibit the house.
Hobo spider is among many arachnid species which are present in pacific areas. This spider is an immigrant in Europe and has earned bad reputation for being very poisonous in the US. The name Hobo has a link with spiders that are assumed to spread by the railroads.
Hobo is among the few North America spiders whose bite can be significant medically. While they fear humans, hobo, like other spiders, will tend to defend themselves when threatened. The fear is that the venom can spread strongly to cause necrosis; that is causing infections and killing flesh around the bite. Nevertheless, do not kill or fear each spider seen. This house spider is a great competitor of this spider and keeps it from the house. This spider does not result in harm to animals and humans and is a great pest control agent. It is quite impossible to know the dissimilarity between the giant house and hobo spider with a naked eye.
Hobo spider bites
Bites of the hobo spider in the United States seem to have very serious consequences. Earlier on, scientists searched for causes of strange bites of spiders. They resemble bites from the brown recluse, but medical implications are not very severe. Soon enough, hobo spider was discovered as the cause of these bites. Symptoms of the bite include tachycardia, redness, pain, and worse, necrotic skin lesions. Many bites accidentally happen when the spider get squeezed. For instance, this happens when a sleeping individual rolls and places his limbs over the spider. Many bites from this spider usually occur in bed. One has to be examined by a doctor after the bit immediately.
How to eliminate Hobo spiders
There are a lot of methods of eliminating these spiders like sprays and other repellents. The con of sprays is that you have to search the house for spiders. You need to use special sprays for spiders because majority of arthropods are resistant to insecticides. Traps are the best methods of exterminating them. They lure spiders with pheromones so as to catch them with the sticky glue. The traps are also safe in the house that has house pets and children.
