What should I do if I find a violinist or a black widow spider in my house? – Teach me science

The violinist spider (genus loxoceles) like the black widow (genus Latrodectus) are small arachnids that we can find in our house, it is because in some of them they find the perfect refuge to inhabit.

Given this, there are some very important considerations that you must take into account to know how to act and what to do when observing these organisms, and thus avoid panicking. Remember that acting smart and calm is the best option.

What I need to know about these arachnids

The first thing you need to know is that it is true that both sexes of these arachnids are of medical importance, because after their bite they both have the ability to inject poison that is toxic to humans.

In general, in black widow spiders, the venom is characterized by being neurotoxic, which means that it causes harmful effects on the nervous system, while that of fiddler spiders is distinguished by its enzymes which produce necrosis.

Once this is recognized, it is extremely important that you NEVER attempt to directly manipulate any of these organisms with your hands or any other part of your body.

Another essential consideration that you must recognize is that, despite the danger of their poisons, the reality is that these spiders are not aggressive animals, contrary to what is believed, they are quite “timid”; Most of the time they will not be looking for any type of confrontation or problem, in fact it is likely that observing one inside our house will try to run away.

Knowing this, the reality is that violin spider bites are rare, even in places where they exist in large numbers. In this way, their objective in this life is not to harm you, on the contrary, they have a very important ecological role in each of the ecosystems they inhabit.

What should I do if I find a violinist or a black widow in my home?

The best recommendation that can be made when one of these arachnids is spotted in your home is relocation, and here we tell you what the safest way to do that is.

  1. First of all, it may be important to recognize if we are in the presence of a species of these two genera of arachnids, therefore, to distinguish them from other spiders which are not of medical importance, you can follow the following infographics.

Both were obtained from @Arachno_Things, a Twitter account managed by Diego Barrales Alcalá, renowned biologist of the Autonomous Metropolitan University (UAM) and currently a doctoral student at the National Collection of Arachnids of the Biology Institute of UNAM. With his project on this digital medium, the arachnologist aims to disseminate information relating to arachnids of medical importance.

2. For the relocation, it is essential that it is a task carried out by people who do not have a particular fear of arachnids, since, although the maneuver is not complicated, nervousness could generate complications. The relocation will allow us to save our family members, while respecting the lives of these animals. To do this, you can use the glass and cardboard technique, as you can see in the following video:

As visualized, a glass container is used, as spiders cannot climb on this surface. Once you have successfully captured it, you can release it away from home, remember, at no time should you have direct contact with it.

Finally, the best thing you can do to prevent one of these spiders from visiting your home and taking refuge there is to maintain cleanliness and order inside and out, because dusty places where cleaning is not done regularly are his favorites. You can follow the following considerations: Avoid violin spiders in your home.
