One of the most frequent chores in a house is cleaning the cobwebs from the most unsuspected corners of our home. Although we eliminate them, they keep appearing, this happens because we are dealing with the consequents, not with the real problem. Spiders keep coming to our homes and return to build their nests in the same places. In this article, we will attempt to answer a question that can be a nagging one: What attracts spiders to your home?
What spiders require to build their nests
Essentially, they are solitary animals, they live in areas where they can have two things: food or security. This is one of the first factors to take into consideration. In these two elements there are conditions, among others:
- Adverse outdoor climate. Spiders require stable and relatively warm conditions to live in.
- The presence of nearby predators. This is another factor in their decisions to occupy a particular space. They will always prefer their home to be relatively inaccessible.
- The need to reproduce is another factor to consider. They are extremely fragile beings that require very specific spaces for the care of their young. The more complicated the space to reach it, the better for them and their eggs.
- The presence of others of their species. The reproductive period forces them to arrange their mating dates in areas where others are already present. This is despite their solitary nature, but if we consider a large area, the density of occupation will remain low.
- The presence of food species. This is a fundamental condition. Spiders will be found where there is an abundance of other insects to feed on. They have evolved to specialise in very specific prey, so to find them, just look for the food, and you are sure to find their nests.
- Spaces that are easy to leave when there are dangers. Spiders are predictable. They prefer spaces where escape is easy and quick, especially high places from which they can hang.
Matching the spider’s needs with your home
This is where it gets interesting. Let’s take a closer look at the requirements we have outlined and compare them with human homes.
The right climate
Spiders prefer places where the temperature can be controlled. Nothing better for this than a house where the windows and doors are closed when it is cold. Likewise, when it is warm, they simply open them. This is the thermoregulation they need to survive, and we provide it.
Predators and prey
The balance required for feeding is found precisely in the home environment. Sufficiently hidden from those who eat them and close to those who feed. For example, small birds avoid contact with humans. This encourages spiders to multiply in your home.
Furthermore, in most homes, there are various insects, flies, ants, termites, which are the preferred prey of spiders. This is a factor that involves their location. For example, those that prefer to feed on flying insects will be located on the ceiling or in corners of the ceiling. Those that feed on crawling insects will be in the lower area, especially in dark corners.
Additional protection for breeding
Our houses are generally sheltered areas, with many inaccessible nooks and crannies, which we do not consider important. The reason is simple: they do not affect us in the least. Inaccessible corners for small creatures, dark but ventilated areas are all factors that spiders look for to live and reproduce.
Another aspect to consider is that when it is mating season, they look for other spiders of their species. This is possible when they have already colonised a space, and so your home becomes a permanent breeding ground for spiders.
Structures that facilitate habitat
In this case, it is about the way we build our homes. It is a question of sequential logic. The conditions that make a place habitable for us make it habitable for spiders. As a result, they become quite frequent companions in the home.
Preventing the presence of spiders in our home
There are several things to take into consideration. In this article, we have mainly referred to harmless spiders. Some more dangerous species tend to live away from humans. Others choose areas such as basements or attics where human presence is infrequent.
However, the species that normally occupy our homes are not dangerous. Perhaps what is important in this case is a question of aesthetics. Of course, if you don’t want a horror film type decoration, the ideal is to prevent them from colonising large areas. For this, constant cleaning is ideal. Likewise, preventing the presence of other insects that serve as food for them.
However, you should be aware that there are some insects that are effectively controlled by a limited number of spiders. This is especially important in the case of flies and the like. A pest control specialist is always an option.
