How to Keep Spiders From Making Webs on Your Porch?

Written by Thomas Matthews

Exterminating spiders outside your home sometimes feels like an impossible task. However, you can take steps to keep their numbers down and limit the spread of their webs.

How to keep spiders from making webs on your porch? To keep spiders from making webs on your porch, use web eliminator sprays and spider repellents. The sprays will create a surface on which the spiders cannot spin their webs, and the repellents reduce the spider population. Planting peppermint plants near the porch is another effective mode of prevention.

This post will address how to repel spiders from your porch, as well as the finest sprays and home cures for killing arachnids that are resistant to traditional repellents. It will detail some of the most common porch spiders and whether you should exercise caution near them.

Common Porch Spiders

Common Porch Spiders

If there are webs around your porch, there are definitely spiders near your home. You should note that humans are safe around most arachnids, but some of them won’t hesitate to bite when threatened. 

Accidental bites may also occur when someone squishes a spider. Most of the bites often result in temporary redness and irritation.

However, the bites from certain species will almost always require medical attention. They include the following:

  • Brown recluse
  • Black widow
  • Tarantula

Brown Recluse

Brown Recluse

A brown recluse has a black violin-shaped marking just below the eyes. The violin’s neck curves rearward toward the belly.

Unlike other spiders, this species features a pattern of six eyes in pairs separated by a gap. The majority of spiders have eight eyes arranged in two rows of four.

The brown recluse is poisonous. Therefore, you must exercise caution when interacting with them.

Additional features of a brown recluse include the following:

  • Webs formed beneath objects.
  • On the legs, there are delicate hairs.
  • Body length is around ½ in. (1.27 cm).
  • Legs that are uniformly light in color with no stripes or bands.
  • An abdomen that is uniform in hue and ranges from cream to dark brown.

Grass Spider

Grass Spider

Grass spiders are distinguished by their significantly expanded web-spinning organs. The abdomen is often darker than the carapace and has a lighter median stripe.

This species has a yellow-brown to brown carapace with two darker longitudinal stripes from the lateral eyes.

Their webs are enormous and sheet-like, with an off-center funnel. Homeowners remark that you will notice more webs than spiders since this species is shy. The webs may be on your grass, plants, and porch posts.

Their bites have been known to induce discomfort, swelling, redness, and itching. These symptoms last between one and ten days without causing significant complications.

Black Widow

Black Widow

The presence of female black widows around your porch is a legitimate cause for concern since their bites may result in major medical complications.

Typically, female black widows are glossy black with a red hourglass marking on the underside of the abdomen. They are often found in woodpiles, sheds, porches, and behind stones.

The black widow’s bite may be painful, and the skin may exhibit one or two bite marks with swelling. Typically, pain begins at the bite site and extends to the belly and back. The abdominal muscles may also experience severe cramping or stiffness.

Additionally, nausea, tremors, hard breathing, elevated blood pressure, and fever may occur. Protective clothes should be used while dealing with black widow webs.

Certain tarantula species spin fine webs behind logs, around tree trunks, and on your porch. The webbing is mainly utilized to line the outside of their housing.

Typically, the head-thorax area and legs of these spiders are dark brown. Additionally, their abdomens have a brownish-black color. The most distinguishing feature of these spiders is their size and hairiness.

Although these spiders possess venom sacs, their venom is not dangerous to humans.

Why Are There So Many Spiders on your Front Porch?

You may have so many spiders on your front porch because your yard is a healthy source of spider food. The porch is usually the highest concentration of insects in homes where insects abound, so spiders weave a web to collect as many as possible.

Do Porch Lights Attract Spiders?

Porch lights can attract spiders. These lights attract various nocturnal flying insects, making it an easy-meal zone for insect-eating organisms, including spiders.  

Spiders will spin webs around the light fixtures to capture their meal. The light does not attract the spider; instead, it is drawn to the food.

Because different species have varying temperature requirements, it is improbable that they are drawn to your porch light for the warmth it gives.

Below are some tips on how to get rid of spiders:

  • Apply insect repellent sprays.
  • Routinely vacuum spider webs.
  • Caulk any cracks and crevices on the outside of your home.
  • Remove food, liquid, and refuge sources.

  • It is best to vacuum up webs as you discover them.
