St. Louis is at the height of summer with scorching temperatures making homes warm and uncomfortable. To counter this, residents are aiming to cool their houses down, but this has led an unforeseen issue, an increase in indoor spider sightings. As the temperature rises, spiders become more active, frequently appearing in residential settings.

Increased Spider Activity During Summer

Over the hot summer days, there are often more spiders found inside homes. When temperatures reach between 90 to 95 degrees Fahrenheit, spider activity increases significantly. Being cold-blooded creatures makes spiders more active during warm weather as it boosts their metabolism and drives them to hunt for food vigorously.

The Missouri Department of Conservation (MDC) confirms that spiders live in almost every habitat within Missouri, including human residences. When it’s hot outside during summers, they typically stay in attics but move to cooler areas within the house when temperatures rise even more.

Brown recluse spiders especially contribute a lot towards the functioning of extermination services. While these spiders help control wild insect populations according to MDC data, they can become a nuisance when they infest homes and feed on other pests hiding around the house.

Spiders’ Desire for Shelter

During hot weather, just like humans, even spiders search for cooler places to escape heat. Also, when outdoor temperatures become unbearably high, they manage to get into houses where it is cooler. This behavior is typical even in winters when they try getting into warm homes escaping the outdoor cold.

Apart from extreme temperatures too hot or too cold if the weather turns extremely wet or dry, then too it may result in indoor movement of these creatures as they prefer stable conditions and move if their habitat conditions diverge according to MDC.

Spiders Search for Food and Water Indoors

To sustain life, Spiders need constant access to water. During extreme summers when there’s shortage of water outside, they move indoors looking for standing water. Along with this, food also drives them inside our homes. If enough prey isn’t available outdoors, then crumbs and unattended food inside house becomes their target.

Your home may unintentionally become a breeding place for some species of spider which mate during July August timeframe. After getting indoors they spray pheromones to attract mates which although isn’t noticeable by humans can attract more spiders causing increased sightings.

Spiders Following Prey Inside House

If there are other bugs like ants or flies, then chances of spider infestation are high as these creatures follow their prey. The presence of other insects and the associated vibrations created can be sensed by hairy legs of spiders called trichobothria guiding them towards their prey and into homes.
