The cost to exterminate spiders in your home is $300 on average, but it can cost between $100 and $500 or more depending how severe your infestation is.
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 costs vary depending on several factors. Take the following into account when formulating your budget.
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.
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.
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.
| Removal Method | Cost Range for Single Treatment |
|---|---|
| Spot spraying | $100–$300 |
| Traps | $150–$250 |
| Fumigation | $300–$500+ |
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.
Pros might employ this non-toxic method to get rid of individual venomous spiders. It’s not a practical approach for large infestations.
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.
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.
| Infestation Size | Average Cost |
|---|---|
| Small | $100–$250 |
| Medium | $190–$350 |
| Large | $350–$550 |
| Severe | $600+ |
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.
The extent and location of your spider situation means you might have to factor in other expenses as part of the extermination.
| Add-Ons | Cost Range |
|---|---|
| Inspection | $100–$150 |
| Cleaning | $30–$50 per hour |
| Repairs | $50–$100 per hour |
| DIY materials | $25–$50 |
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 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.
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)
It’s possible to make big savings by removing spiders yourself, with costs as low as $25 to $50. If you’ve just got a few harmless house spiders and can’t face living alongside them, you could trap them in a glass, sweep them out of the house, set up inexpensive traps, or use a commercially available spot spray. It’s also easy to take preventative steps to try to keep spiders out of your home.
If you’re struggling to get things under control, there’s a big infestation, or you're dealing with venomous spiders, it’s usually best to leave extermination to the professionals. A local spider control specialist can target the area with the most effective products (often chemicals requiring a special license or bespoke natural strategies) and offer advice on preventative measures. Professional assistance also provides peace of mind regarding keeping your kids and pets safe when using chemical treatments.
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
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.
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.

Spiders are tiny creatures that can squeeze through the smallest cracks, so it’s impossible to guarantee eradication of every one within a home. However, understanding how to get rid of house spiders helps you be proactive with preventatives, minimizing the chance of an infestation taking hold. And if you do end up with a spider colony, thankfully, there are effective strategies for controlling the numbers.
Although it's easy to eliminate one or two harmless spiders yourself, professional spider exterminators have the tools, licenses, and expertise to reduce or remove major infestations effectively. They can also safely get rid of venomous black widow or brown recluse spiders and offer advice about preventative treatments to help defend against more infestations.
If your house is full of things that attract spiders, you’re more likely to have a population explosion. When you have lots of cracks leading to warm, secure spots in your home, why wouldn’t they want to come in? Especially if your home has plenty of other meal-ticket insects, like flies, roaches, and fleas. Sealing up obvious cracks and gaps and keeping your house bug-free makes it a less appealing place for spiders.
Spiders have lots of scent-sensitive hairs on their legs. Scented oils they aren’t fans of can act as a natural spider repellent to help keep their populations at bay when you rub them around your home’s entry points. Studies suggest mint and chestnut oils are two scents that spiders hate.
