Spiders are a common sight in most homes, but when do a few eight-legged visitors become a full-blown infestation? For many homeowners, the line between a manageable spider presence and a problem requiring professional intervention can be blurry. This guide will help clarify when it’s time to call in the experts, how to identify different types of spiders, and what to expect from professional spider control services. Whether you’re dealing with harmless house spiders or potentially dangerous species, understanding your options is key to maintaining a safe and comfortable home environment.

What Are the Signs of a Spider Infestation?
While the occasional spider sighting is normal, certain signs may indicate a more serious problem. Recognizing them can help homeowners determine when they might need professional intervention.
Excessive Spider Webs
One of the most visible signs of a spider infestation is an abundance of spider webs. Spiders typically construct their webs in high-up areas of the home to catch flying insects. Look for webs in ceiling corners, wall intersections, light fixtures, window frames, and among items on shelves.
A few webs here and there are normal, but if you’re constantly clearing them away only to find new ones the next day, it might be time to consider professional help.
Presence of Egg Sacs
Spider egg sacs are another clear indicator of a potential infestation. These sacs are typically white or off-white, teardrop-shaped, encased in webbing, and hidden in secluded areas. Common locations are basement corners, attic spaces, crawl spaces, garages, and inside unused items.
The presence of multiple egg sacs suggests that spiders are actively reproducing in your home, which could lead to a rapid increase in the spider population.
Increased Insect Activity
Since spiders feed on other insects, an uptick in general bug activity can attract more spiders to your home. If you notice an increase in flies, mosquitoes, or other small insects, it’s likely that spiders won’t be far behind. Addressing the underlying insect problem can help control spider populations as well.
What Constitutes an Excessive Spider Problem?
Determining what qualifies as an excessive spider problem can be subjective, but there are some general guidelines to consider. If you’re regularly seeing multiple spiders daily, finding webs in most rooms of your house, or noticing spider droppings (small, dark spots on floors or surfaces), these could be signs of an infestation.
Spiders tend to gravitate toward dark, moist environments like basements, crawl spaces, and areas under sinks. If these areas seem to be teeming with spider activity, it may be time to consult a professional. Remember, a single breeding pair of spiders can produce hundreds of offspring, potentially leading to a rapid population explosion if left unchecked.
Identifying Spider Species
Understanding the specific types of spiders you’re dealing with can help you gauge the severity of the infestation. Some spiders are relatively harmless, while others can pose health risks due to their venom.
Common House Spiders
Most spiders found indoors are harmless and more of a nuisance than a threat. Common house spiders include:
- American house spiders: Small, brownish spiders that build tangled webs in corners
- Daddy longlegs: These have long, thin legs and small bodies—they’re non-venomous and essentially harmless
- Jumping spiders: Small spiders with good jumping ability, often seen on walls and windowsills
Venomous Spiders
Certain species of spiders pose greater risks due to their venom. These include:
- Black widows: Easily recognizable by the red hourglass shape on their abdomens. Their bites can cause severe pain, muscle cramps, and other symptoms.
- Brown recluses: Light to medium brown with a violin-shaped mark on their backs. Bites can lead to necrotic wounds and serious health issues.
- Hobo spiders: Brown with a distinctive herringbone pattern on the abdomen. Their bites can cause skin damage and other symptoms.
As I’ll discuss further in-depth below, if you identify venomous spiders in your home, seek professional help immediately.
DIY Spider Control Methods
Before calling in the professionals, you can try several DIY spider control methods:
Sealing Entry Points
One of the most effective ways to control spiders is to prevent them from entering your home in the first place. Caulking cracks in the baseboards and around windows and ensuring doors and window seals are intact are good places to start. Also, check for gaps around pipes and cables entering the home. Sealing off any entry points to attics or basements will cut down on avenues for spiders to enter.
By closing off these access points, you not only keep spiders out but also prevent the entry of other insects that spiders prey on.
Using Sticky Traps
Sticky traps can be an effective and nontoxic way to capture spiders. They work by attracting spiders with bait and trapping them on a sticky surface. Sticky traps come in many forms, so trial and error is your best bet to find the most effective one for your home.
Place traps in corners, along baseboards, and in other areas where you’ve noticed spider activity. Replace them every three months or when they become full.
Removing Webs and Egg Sacs
Regular cleaning to remove webs and egg sacs can discourage spiders from settling in your home. Use a long-handled duster or vacuum attachment to reach high corners and ceilings. Pay special attention to often-overlooked areas, such as behind furniture and in storage spaces.
Natural Repellents
Some natural substances are thought to repel spiders. Some homeowners find success with spray treatments of essential oils such as peppermint, tea tree, or lavender or a spray made with white vinegar.
These natural options can be a good first step for those who prefer to avoid chemical pesticides.
Professional Spider Control: What To Expect
If DIY methods prove ineffective or if the spider problem seems overwhelming, it may be time to call in professional pest control services. Here’s what to expect from a professional spider extermination process:
Initial Inspection
A pest control professional will start with a thorough inspection of your property. They’ll look for signs of spider activity, potential entry points, the presence of other insects that spiders prey on, and conditions that might be attracting spiders.
This inspection helps the exterminator develop a treatment plan specific to your home’s needs.
Treatment Methods
Professional exterminators use a variety of methods to control spider populations. They often use liquid or powder-based pesticides in key areas where spiders might enter or travel within the house and may even use Industrial-strength repellents around the home’s perimeter to deter spiders from entering the home in the first place.
Some treatments are specific to the type of spider. For severe infestations or dangerous spider species, more intensive methods like wall injections may be needed.
Follow-Up and Prevention
Many pest control companies offer follow-up visits to ensure the effectiveness of their treatments. They may also provide advice on preventing future infestations, such as reducing household clutter that provides hiding spots for spiders, maintaining a clean and dry environment, and regular inspections to prevent infestation before it becomes a problem.
How Much Does Professional Spider Control Cost?
The cost of professional spider exterminator can vary widely depending on factors such as the size of your home, infestation severity, and treatment required.
According to Angi, homeowners can expect to pay between $100 and $500 for a one-time spider control treatment. For ongoing pest management plans, costs will vary by provider and the specific needs of your home.
Get quotes from top pest control companies and make sure you’re clear on exactly what services are included in the price. Some companies offer guarantees or free re-treatments if the problem persists after initial treatment.
When To Call an Exterminator Immediately
While many spider situations can be handled with DIY methods or can wait for scheduled pest control, there are times when you need immediate professional intervention:
- If you identify venomous spiders such as black widows or brown recluses in your home
- If you or a family member experiences a spider bite with severe symptoms
- If you have a sudden, large-scale infestation that overwhelms your ability to manage it
- If spiders are entering living spaces in large numbers, particularly in homes with small children or pets
In these cases, don’t hesitate to call a professional exterminator right away. The potential risks of venomous spiders or severe infestations outweigh the cost of emergency pest control services.
Final Thoughts About Spider Control
Dealing with spiders in the home can be a challenging and sometimes frightening experience. While the occasional spider is usually harmless and can even be beneficial in controlling other insect populations, an infestation can quickly become overwhelming and potentially dangerous.
The key to effective spider control is early identification and prompt action. By recognizing the signs of an infestation and understanding the options available—from DIY methods to professional extermination—homeowners can make informed decisions about how to protect their living spaces. Whether choosing to tackle the problem yourself or calling in the experts, the goal remains the same: a safe, comfortable, and spider-free home environment.
