How Much Does Spider Removal Cost? [2026 Data]

The average professional spider exterminator cost is $300, but typically varies from $100 to $500, depending on the size of the space, the frequency of visits, and the type of treatment. DIY removal methods might cost less than $50. For the most part, you don’t need to kill spiders in your home. They are generally harmless creatures that prey on pesky flies and other problematic pests. However, large infestations aren't desirable—especially if you’re an arachnophobe—and you don’t want venomous spiders setting up a home in your house. This is when understanding the costs of having spiders professionally removed and kept away is helpful.

Spider Exterminator Cost Factors

Spider exterminator costs vary depending on several factors. Take the following into account when formulating your budget.

Size of Area

The size of the space needing treatment influences the price. If the pros only have to spot-spray a nest in a small room corner, it will cost less than fumigating an entire basement. Calculate approximately $0.15 to $0.20 per square foot as a rough guide. However, a minimum fee usually applies for spot treatments or trapping.

Frequency of Treatment

If you discover an individual venomous black widow or brown recluse spider on your property, you might want a one-time visit to get rid of the creepy crawly pronto. For homes prone to infestations, even of less harmful species, having an exterminator visit regularly can help keep populations at bay.

A one-time reactive visit typically costs $100 to $300. Budget $350 to $750 annually to have the pros eradicate and evaluate preventative measures quarterly. And, if you’re an arachnophobe living in a spider hotspot, investing in monthly preventative visits can put your mind at ease. However, you could pay up to $1,000 annually for the privilege.

Removal Type

Depending on the size of the spider infestation, location, and species of spider, the professionals can adopt different approaches for eradication. The removal method often affects the price you pay.

Spider Dust or Spot Spraying 

These products are often only suitable for use by licensed professionals. They leave a fine layer of spider-killing chemical dust or targeted spray in areas where arachnids frequent. 

Traps 

Pros might employ this non-toxic method to get rid of individual venomous spiders. It’s not a practical approach for large infestations.

Fumigation

This method could set you back even more than $500, depending on the size of the area being treated. Pros use strong chemicals that fill an entire room or home with gaseous spider-killing chemicals. This is effective for large infestations in bigger areas, but it is the most expensive option, and some products are only legal for use if you have a license.

Level of Infestation

If you just have one or two spiders in your home, the professionals will typically charge less than they would for dealing with a spider scourge. A big infestation requires more time, chemicals, and possibly even repeat visits to deal with it. If you also want exterminators to help you put in place preventative measures, allocate a bigger budget than for a one-time trapping. 

Location

A spider’s nest in your chimney is more tricky to remove than one in a corner of the kitchen ceiling. Expect professionals to charge more when accessing difficult-to-reach spots around your property.

Additional Spider Extermination Costs to Consider

The extent and location of your spider situation means you might have to factor in other expenses as part of the extermination.

Inspection

If you’re overrun with spiders, it’s clear that you need to take action. However, it’s more tricky if you just spot a solo spider. You might be worried about it being poisonous or whether there are more creepy crawlies hiding away. In these instances, arranging an inspection can be helpful. Inspections typically cost between $100 and $150, but some companies waive this fee if you go ahead with an extermination job.

Cleaning Service

Cleaning up copious cobwebs from a major basement spider infestation might not appeal if they give you the heebie-jeebies. In these instances, expect to pay $30 to $50 per hour for professional house cleaning costs.

Repairs

The professional exterminators may have to alter your home in order to apply treatments to the infested area. If that’s the case, you should budget for the necessary post-treatment repairs.

• Repair drywall: $50 to $75 per square foot

• Recaulking windows and cracks: $105–$290

• Remove a wall: $1,000–$10,000 (severe infestations only)

Why You Should Hire a Spider Control Pro

The best way to put an end to your spider infestation is by hiring a spider exterminator near you. You may be able to DIY the fix if the pests are harmless house spiders and the affected area is small, but you’ll need a knowledgeable exterminator to use professional-grade products and recommend the safest way to eradicate dangerous species. 

Here’s why it’s ideal to hire a spider exterminator

Here are some of the benefits of hiring a spider control professional:

• A spider control pro can evaluate the infestation and let you know if they recommend spider removal or if what you’re noticing is a normal amount of critters.

• If you don’t know which species you’re dealing with, it’s best to bring in a pro to avoid health complications from venomous spider bites.

• Clearing out a large spider infestation, regardless of the species, may require professional-grade products.

• Hiring a pro, especially for regular treatments, gives you peace of mind knowing that the infestation won’t return.

• Your exterminator may notice additional pests that need to be addressed while working on the spider removal, which can help prevent a larger issue in the future.

If you want to DIY spider removal

Hire a specialist to safely take care of a big infestation or venomous spiders, but if you have a few harmless house spiders, you can try:  

• Trapping the spiders in a glass

• Sweeping them out of the house

• Setting up inexpensive traps

• Using a commercially available spot spray

Cost of Common Spider Removal Add-Ons

If you’ve been experiencing problems with other pests on your property, now’s the time to tackle them. Pest control specialists often offer discounts to eliminate multiple creepy crawlies as part of the same job.

Other common pest control costs include:

• Flea extermination costs: $150–$400

• Ant extermination costs: $100–$500

• Bed bug extermination costs: $350–$5,000

• Cockroach extermination costs: $100–$600

• Wasp extermination costs: $100–$1,300

Tips to Reduce Costs When Removing Spiders

You can still make savings, even if you don't want to go down the DIY spider removal route. Here are some ways to reduce your final bill.

• Shop around: Ask for prices from at least three reputable, licensed pest control companies rather than opting for the first one you contact.

• Be proactive rather than reactive: While it’s impossible to 100% guarantee spiders won’t enter your home, you can reduce the chances of them becoming tenants. By putting preventative measures in place, you're less likely to need to call the pros.     

• Don’t wait to get help with an infestation: When there’s a big population of spiders, don’t delay calling the professionals. Holding off in the hope they move on usually means the job will get bigger and more costly the longer you wait.

Signs of a Spider Infestation

Seeing a stray spider on the wall or scurrying across the floor is completely normal, albeit unpleasant. As a result, some homeowners may not be able to tell when there’s a more serious spider infestation that warrants action. Here are the key signs to look out for.

• Webs: An excess of cobwebs can mean an excess of spiders abound.

• Egg sacs: The sight of an egg sac holding potentially hundreds of baby spiders warrants a call for an exterminator.

• Insects: If your house gets a lot of flies and mosquitos, it could attract spiders, as arachnids prey on insects.

• Frequent bites: Spider bites happen. Recurring spider bites, however, could indicate an infestation.

• Loads of spiders: If you see several spiders (living or dead) at once, there’s likely an infestation.
