Spider extermination costs $100 to $500 for most homeowners, with Angi and HomeAdvisor both publishing a $300 national average.1,2 Fixr publishes a $400 national average for a one-time visit and spray treatment in a 2,500-square-foot home, within a $300 to $500 range, from a guide updated in January 2025.3 Prices below are national averages*.

*National averages, not local quotes. Angi figures are from a 2026 guide updated October 2026, HomeAdvisor figures are from a 2025-data guide updated June 2026, and Fixr figures are from a guide updated January 2025. Your price depends on the infestation size, the treatment method, and how often a pro visits.

Safety note: the CDC says venomous spiders found in the United States include the black widow and the brown recluse – black widow venom is a neurotoxin, and brown recluse venom can destroy skin tissue and requires professional medical attention. Most bites happen when a spider is trapped or touched, so leave a suspected venomous spider to a professional rather than handling it.4

What the sources say

Source Headline figures Notes
Angi (updated Oct 2026) $300 national average; most jobs $100 – $500 Prices a $0.15 – $0.20 per-sq-ft starting rate, with a minimum fee for spot treatments
HomeAdvisor (2025 data, updated Jun 2026) $300 average; same $100 – $500 normal range; small treatments as low as $50; severe infestations in large homes can exceed $1,200 Corporate sibling of Angi – matching figures alone don’t establish independent corroboration
Fixr (updated Jan 2025) $400 national average for a one-time visit and spray treatment in a 2,500 sq.ft. home; range $300 – $500; low-end $100 (a single visit with spider dust treatment in a 1,000 sq.ft. space); high-end $700 (fumigation in a 3,500 sq.ft. home or garage) Average covers a defined job scope

The sibling pair publishes identical headline figures, presented as published. Fixr’s figures are separately published and older (January 2025), with no shared sourcing stated, and its average covers a defined job scope, so they are presented separately.

Cost by extermination method

The publishers price overlapping methods at different figures, and Fixr’s method prices include the inspection, treatment, and monitoring. The rows are not compared directly.1,3

Method Cost Source and scope
Spot spraying $100 – $300 Angi
Traps $150 – $250 Angi
Fumigation $300 – $500+ Angi
Spider dust $100 – $250 Fixr (2025), inspection included
Traps $100 – $300 Fixr (2025), inspection included
Spray $200 – $500 Fixr (2025), inspection included
Fumigation $300 – $1,000 Fixr (2025), inspection included

Cost per square foot and by home size

Angi and HomeAdvisor publish a matching $0.15 – $0.20 per-square-foot rate, with HomeAdvisor pricing a whole 2,000 sq.ft. home at $300 – $400.1,2 Fixr publishes a $0.10 – $0.20 rate and the per-treatment table below; the two rates differ, so they are not compared directly.3

Home size Cost per treatment (Fixr, 2025)
1,000 sq.ft. $100 – $200
1,500 sq.ft. $150 – $300
2,000 sq.ft. $200 – $400
2,500 sq.ft. $250 – $500
3,000 sq.ft. $300 – $600
3,500 sq.ft. $350 – $700
4,000 sq.ft. $400 – $800
5,000 sq.ft. $500 – $1,000

Cost by infestation size

All three publishers price by infestation size, with different presentations: Angi publishes ranges, HomeAdvisor publishes point averages, and Fixr publishes wider ranges. The figures differ, so the columns are not compared directly.1,2,3

Infestation size Angi HomeAdvisor Fixr (2025)
Small $100 – $250 $175 $100 – $300
Medium $190 – $350 $270 $150 – $400
Large $350 – $550 $450 $200 – $600
Severe $600+ $600+ $300 – $1,000

Angi and HomeAdvisor publish the same $600+ severe figure; matching figures alone don’t establish independent corroboration between the corporate siblings. Fixr defines small as 1 to 5 spiders, medium as up to 20, large as up to about 100, and severe as beyond that.

Cost by location

Fixr (2025) prices a one-time perimeter and interior pesticide treatment by where the spiders are.3

Location Cost per treatment (Fixr, 2025)
Deck $75 – $250
Patio $75 – $250
Carpet $100 – $300
Bathroom $125 – $300
Bedroom $125 – $300
Kitchen $125 – $300
Shed $125 – $300
Yard $150 – $450
Attic $170 – $500
Basement $400 – $1,000
Garage $400 – $1,000

Angi notes hard-to-reach nesting spots cost more, without publishing per-location figures.1

Cost by treatment frequency

Angi and HomeAdvisor publish matching per-year frequency figures; the quarterly figure also matches Fixr’s, while the monthly figures differ and are not compared directly.1,2,3

Frequency Cost per year Source
One-time $100 – $300 Angi / HomeAdvisor
Quarterly $350 – $750 Angi, HomeAdvisor, and Fixr (2025), matching figures
Monthly $1,000 Angi / HomeAdvisor
Monthly $600 – $1,250 Fixr (2025)

The matching quarterly figure is separately published across different owners, and the pages state no shared sourcing. Fixr also prices preventative treatment at $100 – $500 and reactive treatment at $250 – $800, depending on property size and visit frequency.
