Spider Control 101

Clark's Pest Control

When spiders come out to play, Clark’s can save the day! Read more to learn about poisonous spiders, how we treat them, and how you can help prevent them.


“What kind of treatment for spiders do I get with my general pest control service?”

We treat from the foundation of your home, 2 feet up and 3 feet out as a protective barrier, as well as all possible points of entry for pests like cracks/crevices in door and windows. It also covers brushing down spider webs with a pesticide around eves, doors, windows, lights, garage, and any other areas on the structure that a spider has built a web. It is normal to see spiders, as they are the most difficult pest to treat, their legs are long and they walk right through the treatment.

They don’t clean themselves, so the only way for product to be applied to them is by direct spray or ingestion of a pest with treatment on it. During your pest control service, the pest professionals can knock down any webs, take care of any spiders seen and treat for any food source they may be thriving off of. If any poisonous spider is found in or around your home you can count on Team Clarks to get rid of them.

“What kind of spiders are dangerous?”

According to PestWorld, there are two species in the southern and western United States that can cause serious harm when accidentally disturbed – the black widow and brown recluse.

black widow spider
Black Widow

You are probably familiar with the black widow’s appearance. It has an almost glossy sheen to its body and has an hourglass-shaped red mark on the underside of its abdomen.

The male widow spider is smaller than the female and rarely bites. The more aggressive females bite more often but will still usually only bite in defense. The most common reason for them to attack is if they are guarding or laying eggs.

The female black widow prefers to spin her silken web in a protected space, such as under decks, house steps or stones. They are rarely found inside of houses. The black widow bite produces sharp pain that typically lasts for hours, resulting in localized muscle cramps.

The pain can become severe and spread to other parts of the body and be accompanied by tremors and weakness. Cold clammy skin, a feeble pulse, spasmodic breathing, and delirium might also be experienced.

Brown Recluse
Brown Recluse

Wolf Spider

The brown recluse spider appears harmless. It is yellow to light brown in color and on the smaller side, with its body only measuring around 3/8” long. When its long legs are extended, its length grows by more than an inch. The brown recluse is often confused with the much larger wolf spider. The easiest way to identify the brown recluse is its three pair of eyes.

It won’t seek out humans to attack, as it is shy by nature. It typically hunts for prey at night and hides during the day.

However, its hiding places can lead to accidental encounters with humans as they like to hide in ceiling light fixtures, under insulation in attics, under furniture, in boxes or in closets.

These locations are prime areas for them to be accidentally found and bite in defense.

“I have general pest control services with you, why would I need Spider+ services?”

Our Spider+ Control service, which includes 8 enhanced spider treatments to the home, treats up to 1/2 acre and directly attracts & attacks spiders.

We use a fog machine to target your yard as well as above the first main floor of your home. This also covers structures on your property like docks, boats, etc. and is great if you live near a body of water.

The 8 treatments also come with a monthly guarantee in between services.

“Is there anything I can do myself to treat spiders?”

Light Leak Test

You’ll notice that the spider webs come out where there’s light. This is because the spiders know how to hunt for their food and that’s what they are targeting. You are most likely to see them around your porch light, flood light, etc.

To perform a light leak test you must do the following:

Wait until dark and then turn on all interior lights and close all blinds, curtains, shutters, windows and doors.

Go outside and see if there is any light “leaking” through.

Vacuuming, Hairspray, and Windex – Who Would Have Thought?

Between services, we recommend vacuuming up any webs and spiders to keep their quickly growing population under control, making sure to properly dispose of any dead pests (aka their food source), and refraining from using over the counter pesticides as they can counteract with our treatment.

You can use Windex or hairspray to kill any pests you see.

We also offer a service targeted directly to spiders for the exterior of your home, please let us know if you have any questions or concerns or would like more information on our Spider + services.

“Do spiders benefit the environment?”

Spiders can help keep down the chances of flying insects invading the inside and outside of your home. Their food source is other bugs. As long as they stay hungry and searching for food, they can be more helpful than harmful.

Chances are you will never experience the bite of a black widow or brown recluse spider, however, that doesn’t mean you have to share your home with these pests.

Thankfully, you can get rid of all types of terrifying spiders around your property today by calling Clark’s Termite & Pest Control. Give us a call at our toll-free number 866-781-4991.


Spiders, Spiders Everywhere!

Spider Facts:

Brown Recluse
  • There are currently over 3000 species of spiders in North America but thankfully in our service area we only have to be concerned about the Brown Recluse and the Black Widow.
  • Spiders have horrible eyesight. A spider is even unable to see a human until they are about a foot away from it!
  • Unlike other insects, spiders do not clean themselves, so spiders can crawl through the pesticide all day long and not die. This is due to the fact that pesticides work by having the pest crawl through the dried pesticide, get it on their feet, clean themselves, ingest the pesticide and die.


How to Prevent and Get Rid of Spiders in your Home

If your home currently has spiders or you would like to prevent spiders from entering, these few tips will help:

  • Vacuum up all webs along with the actual spider.
  • Perform a light leak test and seal all cracks and crevices around doors and windows.
  • Replace exterior white lights to yellow lights. This attracts fewer flying insects which will lead to fewer spiders.
  • Trim bushes around the house.


How to Perform a Light Leak Test

To perform a light leak test you must do the following:

  1. Wait until dark and then turn on all interior lights and close all blinds, curtains, shutters, windows and doors.

2. Go outside and see if there is any light “leaking” through.


If you have a spider problem, our Quarterly Pest Control Service guarantees spider control on the inside and within the treatment zone on the exterior, and we also have Spider Control service for yards, landscaping and other areas as well.

Cellar spiders are usually found in dark corners of cellars, crawlspaces, and garages. They are very long-legged and often confused with daddy-longlegs best slimming products.

Brown Recluse Spider

Brown ReclusePhysical Characteristics

Over the years, the group of spiders to which the brown recluse belongs has been known by various colloquial names: “violin” spiders, “fiddleback” spiders, “recluse” spiders, and “brown” spiders. Many publications refer to the violin marking on the top surface of the head region as the most important diagnostic feature. Although this marking is fairly consistent in mature brown recluses, it can vary in intensity and sometimes fades in preservative, and it is very faint to nonexistent in several recluse species. To be identified as a recluse spider, it must have all five of these characteristics.

  • six eyes in pairs as opposed to eight eyes (like most spiders)
  • uniformly colored abdomen with fine hairs
  • no spines on the legs
  • uniformly colored legs
  • body not more than 3/8” in length


Recluse spiders, as their name implies, are reclusive natural slimming pills. These nocturnal spiders emerge from their retreats at night and actively hunt down prey or may wait for prey to land in the small area several inches from their retreat. Although they do not build webs to capture prey, they do use silk to build a retreat in which they hide during the day. As dawn approaches, they may seek shelter in dark places such as in clothing or shoes. In nature, recluses are found in cracks and crevices in and under rocks. Recluses have very much benefited from human-altered environments where they are readily found under trash cans, plywood, tarps, or rubber tires, in boxes, etc.

Black Widow Spider

Black Widow SpiderPhysical Characteristics

The adult female is about 1/2″ including an almost spherical abdomen about 1/4″-3/8″ in diameter with overall length including legs of about 1 1/2″-1 3/8″. Females are black in color with identifiable marking of a red hourglass.


Black Widows can be found in irregular webs and hang upside down or in sheltered places, such as under stones, firewood piles, under decking, hollow tree stumps, trees and rodent burrows. A favorite place is in barns, outhouses, henhouses, sheds, meter boxes, bricks, barrels and woodpiles.


Part of the Clark’s Pest Control treatment is not only providing a residual barrier for the control of insects and spiders, but to also physically sweep down all accessible spider webs Look At This.
