Poisonous spiders in Idaho

                In the early 1990s in the wake of the movie Arachnophobia, it was nearly impossible to not harbor on at lease some level, a fear of poisonous spiders. Unfortunately, these sorts of fears have given spiders a bad rap. The purpose of this article is to address which spider bites in our area can if fact, cause a serious reaction. This way those beneficial spiders in our yards can be left to do their thing!

                The first thing I would like to point out is that depending on how one reacts to a bite, determines its toxicity. Those that we categorize as poisonous, tend to have specific venom known to cause issues in majority of the cases where the bite occurs. Those that are categorized as harmless can in some cases cause a reaction, in the same way a bee sting can deeply affect some and cause little annoyance in others. I think it is reasonable to assume that most spiders can affect certain persons, it just depends on the particular aliments of the individual.


 blackwiddow.gif                The first and by far the most dangerous spider in our area is the black widow. This spider (the female as it is the type that carries the poison) can be identified easily by it usual shiny black color, elongated upper body, large bulbous sac that resides toward the back of the spider and the signature broken hour glass shape on its abdomen. This particular spider is extremely dangerous as it harbors a poison which is a neurotoxin. The big deal here is that the venom on rare occasions cases cause death (mostly when a young child or elderly people are bitten). The bite of the spider is usually not too painful so it is difficult to identify the bite when it occurs. The venom can cause muscle spasms and cramping which can be extremely painful. In some of the more extreme cases the venom can cause anxiety, profuse perspiration, nausea and high blood pressure. Fortunately, black widows cannot see well and likes to stick to its large sloppy web. The prefer areas that are dark and damp so our well lit living spaces are less than desirable for them. Also, black widows tend to be passive creatures that bite only when provoked. It is when we put on a shoe or disturb a web while working under a home where the bite most often occurs. For those that need to work under a home or are cleaning out an old attic, we at Zamzows recommend a bug bomb for those areas. This will do a very good job of clearing the area out so it will be safe to work in the dark, damp areas. The great thing about the black widow is that they tend to keep to their own and do not often venture into well lit areas. This means more often than not, these spiders do not make contact with people!

      The second and more mobile of our venomous spiders is the hobo spider. This particular spider is called a hobo because of its ability to hitch a ride moving the spider quickly from place to place. The hobo spider traces it roots to the range outside of France . The spider can be identified by its larger body, very long legs and its two boxing gloves that actually are their sex organs. During most of the season the spiders are docile. It is during the later months of summer when the females create there funnel like webs and the males go to search them out. This is when the real trouble begins as the males come indoors, often in large numbers, in search of a mate. The bite of the hobo is not often poisonous as they do bite in a dry sense, where no venom is injected because it is reserved for prey. In the case that venom is injected, the bite will turn red and swell. Some individuals are able to heal quickly, others are not. The bite of a hobo is similar to that of a brown recluse in its effect, however its effect is no where even close to the severity of the brown recluse bite. Much like the black widow these spiders are defensive. They dont see well and would much rather run then make contact. They scurry toward the nearest area for cover, which can sometimes be a person making them seem like they are attacking.  Most of the bites occur while putting on a shoe or intruding on an area the spider has decided to hide in.  As the years have passes since this spider was first identified, it has become an increasing problem in our Idaho residences. We suggest that spider traps be placed in strategic locations like near the garage entry and any other outlets to you home from the outside. We also strongly suggest our Zamzow One product to create a barrier outside of the home or even on the inside of the home as a blockade for the spiders. The residual of our product is roughly two weeks barring tons of rain in an outside setting. Using these two products in combination with one another can provide any home with the ability to protect itself from invasion!

                The final spider that is actually not able to survive here is Idaho is the brown recluse. brownrecluse.jpgThis is considered by most to be the most feared of all spiders in the United States . Brown recluse are found in much warmer areas that do not undertake the types of winters we receive in Idaho . This does not mean however, that they do not show up here on occasion. They can hitch rides on many different mediums and make an appearance, fortunately for us this is fairly infrequent. The bite of a brow recluse can vary in severity and is often not too dramatic. In worst case scenarios the venom of the recluse causes a massive gash in the skin to from that takes weeks, possibly even months to heal. The most important thing for Idaho residents to realize about this spider is that it does not reside here!
