Are Spiders Serious?

Dealing with any type of pest infestation can be alarming, and spiders are no exception. Most species of spiders are relatively harmless and do not pose a huge danger to humans; however, the bite of some spider species can cause significant damage to people’s health and safety. Two of the most dangerous species, the Brown Recluse and the Black Widow, live in the California region and should be treated with extreme caution.

How Do Spiders Get Into My Home?

Spiders enter your home for a variety of reasons —searching for food, shelter, moisture in your basement, or even a mate. The presence of other pests that are spiders’ food sources, such as flies and bugs, can also draw spiders into your home. Any small opening is an invitation for a spider to enter your property. Small cracks under doors and windows can let spiders into your home easily. Some spiders can accidentally be brought into your home through plants, firewood, or other objects, such as boxes of clothes. A spider living on that material can then explore other places around the house once safely inside.

Spider life cycle from eggs, to babies, to young and finally adults.

Life Cycle and Reproduction

Spiders are born from an egg sac that contains thousands of other spiderlings. As spiderlings grow, they continuously molt until they reach their adult form. During the reproduction phase of the spider’s life cycle, males generally court the females in elaborate displays. After, some species of females will consume the male. The average lifespan of a spider is around 2-3 years, but certain house spiders can live for up to seven years.

Behavior and Diet

Spiders can be found in a variety of different climates and locations. Some spiders prefer cool indoor cracks and moist locations while others thrive in dry, hot areas. While the diet ranges by species, many spiders consume insects and other spiders as their source of food. Spiders’ powerful digestive enzymes help them break down food, as they cannot chew.

How to Kill Spiders

Killing spiders can be a daunting task if not left to professionals. Many species of spiders, especially in Southern and Central California, are dangerous to humans. Rather than attempting a DIY pest removal and risk injury to yourself, always call a professional to remove spiders from your property.
