Why Do I Have an Increase in Spider Problems?

Unless it is Halloween or a few days before, nobody likes to see webs strewn across their home. Even less do we like to see the actual, 8-legged creatures scurrying across anything related to our living space. Understanding a few key things about spiders will answer the common question we get, “Why do I have an increase in spider problems?”

The underlying answer to spider questions is related to food. Spiders are carnivores. They feed on other arachnids and insects.

Some spiders are hunters and others are trappers, but the end result is the same. They need food to survive and plenty of food makes them thrive.


Light plays a major roll in spider activity. Certain insects are attracted to light – especially flying insects. Spiders love to catch these scrumptious flyers in their webs. Changes in the flow of light will change insect activity and result in changes in spider activity.

These changes in light may occur in conjunction with seasonal changes, redecoration, upgrades to lighting, or even behavioral changes in the residents of a structure. In some cases it is exterior lighting and others could be interior lighting flowing outside through open curtains. You can make minor or major changes to light to affect the insect population’s behavior.

In addition to reducing the light around an area with an increase in spider activity, you can also change the type of light. Yellow CFLs, sodium vapor and halogen bulbs are more likely to go unnoticed by insects.


Insects need water to keep healthy populations. As moisture levels increase in an area, insect activity is sure to follow. As insect activity increases, hungry spiders are quick to join the throng. This could be an increase in humidity levels, water condensation on pipes, or something leaking. Dehumidifying or stopping the water flow to an area will help restore a proper balance.

Change In Activity

Especially relevant to 2020 is the changes in human activity. While some insects like mosquitoes seek out human activity for a tasty treat, most insects like to avoid the bug-smashing human feet. Areas that get less foot traffic are likely to be safe havens for shy insects. As insects find these comfortable congregation places, spiders will follow them in for sustenance.

Luck Of The Wind

Sometimes, the answer to the question “Why do I have an increase in spider problems?” is nothing more than bad luck. For example, some spiders use ballooning to disperse as young spider hatchlings. In this instance, it could simply be a situation where the wind was blowing your direction when the hatchlings caught a silky ride on the breeze.

In some cases, spiders can take a solid stronghold in an area where little to no adjustments to light, moisture or activity can reasonably occur.
