The short version
Ask every pro for the same itemized quote: initial visit, dewebbing and egg sac removal, interior treatment, exterior perimeter, sealing gaps, recurring visits and callback terms. Put the lines in one table and compare the first-year total, not the headline price. A quote that is cheaper per visit but leaves out dewebbing or ladder work usually costs more once you add what is missing.
- Request the same items from every pro so quotes are comparable.
- Compare first-year totals including the initial visit and callbacks.
- Dewebbing height and egg sac removal are the lines that separate spider quotes.
- Sealing gaps is rarely in the base price but often ends the problem.
- A quote that names your rooms and findings beats one that does not.
- Research: Across 50 North Carolina homes inspected in 2012, Bertone and colleagues found spiders in 68.5% of the 146 bathrooms, the lowest room-level share in their study.
For homeowners collecting quotes for a first spider service, for anyone comparing a renewal offer against competitors, and for property managers who need quotes that map onto a unit list. It assumes you have a rough idea of where spiders are showing up, which a short inspection walk provides.
What to look for
If nobody asked which rooms have activity or whether you have a two-story eave line, the quote is a guess. The fix is to send every pro the same short description and the same list of items to price. Spider control quotes are not standardized. One pro prices a ground-level perimeter spray and calls it spider control. Another includes brushing every eave from a ladder, removing egg sacs, treating interior cracks and crevices, and a thirty-day free callback. The second costs more per visit and is often the better deal, but a side-by-side of headline prices hides that. Quotes are also written to the company's standard package, not to your house.
- 1Webs at eaves, corners and fixtures rebuilt within days.
- 2Egg sacs in garage corners, closets or under decks.
- 3Spiders indoors in several rooms over a month.
- 4Web lines across doorways and window frames.
- 5Dark droppings on sills beneath regular web sites.
- 6Shed skins and spiderlings near a single corner.
Why it’s worth acting soon
- Choosing on headline price locks in a plan missing the key services.
- Uncompared callback terms turn returning spiders into surprise invoices.
- Egg sacs left in place hatch before the plan even starts.
- Sealing gaps omitted from every quote means spiders keep entering.
- A year-long term signed quickly is hard to leave.

Mesh and sealant around a pipe entry close off a gap spiders would otherwise use.The request to send every pro.
Attach three photos. Describe the problem in three or four lines from your sighting log: which rooms, which exterior areas, how often, and whether you have found egg sacs or a suspected widow or recluse. Describe the house: stories, approximate square footage, eave height, garage and outbuildings, deck. Keep it to one page. You will immediately see who read it and who sent their standard sheet. Send the identical request to each pro. Ask for the quote with each item on its own line, and ask whether an on-site inspection is needed before a final price. Products: names so you can read the labels. Term: initial length, renewal, cancellation notice and any fee. Sealing gaps: what would be sealed, with what materials, at what price.backs: free window and fee outside it. Recurring service: frequency, per-visit price, dewebbing on each visit, interior on request terms. Initial visit: dewebbing at all eaves, soffits, fixtures and corners, with the height reached; egg sac removal; interior crack-and-crevice application in the rooms listed; exterior perimeter application. Then list the items to price, in this order.
Building the comparison table.
At the bottom, compute the first-year total: initial visit plus recurring visits for the rest of the year plus any sealing gaps you intend to have done. Add rows for the free callback window, the term length, the cancellation fee and the dewebbing height. Fill in the price for each row, and beside it a one-word note on what's covered: included, extra, excluded, or unclear. Make a table with one column per pro and one row per line item. Keep the table with the signed agreement and compare service tickets to it. Dewebbing to the second story rather than the first is the difference between a house that looks maintained and one that does not. A thirty-day free callback window is worth a visit or two a year. A month-to-month term is worth real money because it lets you leave a plan that is not working. Weigh the non-price rows. A quote far below the others almost always has rows marked excluded; add the missing items at typical published ranges to see the true comparison. A quote with several rows marked unclear needs a follow-up email. The cheapest first-year total with every row marked included is your leading candidate. If a pro's callback window is short, add one or two callbacks at their fee.

A weak answer says they will spray the perimeter and inside as needed. It names a product and estimates time. When you ask about the initial visit, a good answer describes a sequence: brush and vacuum webs and sacs at eaves, fixtures and corners using an extension pole and, where needed, a ladder; apply a labeled residual to cracks and crevices in the rooms you listed; treat the exterior foundation, door and window frames and eave lines. Make sure the final list of work is in the agreement before you sign, and keep your table for the day the renewal offer arrives. Choose the pro whose answers are most specific to your house, not the lowest number. On products, a good answer is a name you can look up. On callbacks, a good answer is a number of days and a fee. A pro who says plainly that they do not do sealing gaps is acceptable, but then you need another pro for that line. On sealing gaps, a good answer lists candidate gaps from your photos, names materials such as door sweeps, silicone sealant, copper mesh or hardware cloth, and gives a price. A weak answer says interior is usually not necessary. On recurring service, a good answer specifies frequency, confirms dewebbing on every visit, and says interior is available on request at no charge.
What affects the price
- Square footage and number of stories.
- Eave height and whether ladder work is required.
- Number of rooms with recorded interior activity.
- Garage, shed and deck coverage.
- Visit frequency and length of the initial term.
- Presence of widows or recluses requiring more interior work.
When to call for help
Send the same request to three pros, then look for the ones who respond to your specifics: a pro who says the garage sacs and the basement sill findings suggest both exterior entry and an established interior population, and prices accordingly, is reading your notes. Request quotes once you have a week or two of sighting notes and a few photos, and sooner if you find egg sacs indoors or a possible widow or recluse. If a pro cannot explain a line, mark that quote down. A good answer for each line describes what a technician will do, how long it takes, and what product or material is used. Ask each pro to walk you through their quote line by line.
What you can do yourself
Pros earn their fee on ladder dewebbing across a whole house, crack-and-crevice application with products labeled for that use, sealing gaps at height and at utility penetrations, and identifying widows and recluses. Weigh those lines heavily. A quote that is inexpensive because it skips them is not a bargain; it is a smaller job. Writing the request and building the comparison table are yours to do. You can also handle some lines yourself, which changes the comparison: vacuuming webs and sacs in reachable areas, installing door sweeps, sealing obvious gaps, and switching exterior bulbs to warm colors are all DIY. If you plan to do them, tell pros so their quotes exclude those items.
Simple ways to keep spiders away
- Keep a sighting log so future quotes are based on data.
- Ask for product labels and keep them with the quotes.
- Note eave height and access issues before requesting quotes.
- Complete DIY sealing first so quotes cover only professional work.
- Reduce exterior lighting attractants to lower ongoing pressure.
- Save every quote and service ticket in one folder for renewal time.

Questions people ask
What should be itemized on a spider control quote?
Initial visit with dewebbing, egg sac removal, interior crack-and-crevice and exterior perimeter application; recurring visit price and frequency; dewebbing height; interior terms; sealing work with materials; callback window and fee; term length, renewal and cancellation. If a line is missing, ask for it.
How much does spider control cost?
Sealing gaps typically runs $200 to $1,000 depending on the job. Prices vary by region, home size and how much ladder work is involved. Typical published ranges are $150 to $400 for an initial visit and $40 to $90 per recurring visit, with quarterly plans around $300 to $550 a year.
Why is one spider quote so much cheaper than the others?
Ask the cheaper pro to confirm each line. If they add the missing items, the price often moves close to the others. Usually because it covers less: ground-level spray only, no ladder dewebbing, no egg sac removal, no interior work, or a short callback window.
Should sealing gaps be in the base quote?
Sealing gaps at doors, windows, vents and utility lines is often what stops spiders coming inside. A pro who does not mention sealing gaps at all is selling spray, not solutions. Rarely, but it should be offered as a separate itemized line.
How do I compare a quarterly plan against a one-time visit?
For steady exterior pressure, quarterly usually wins on results. For a single indoor problem with a clear cause, one-time plus sealing gaps often costs less. Compute the first-year total for each: one-time visit plus expected callbacks at their fee, versus initial visit plus recurring visits plus callbacks.
What questions expose a thin quote?
What do you seal and with what material? What is the free callback window? Short, specific answers indicate a real plan. How high do you deweb and with what tool? Do you remove egg sacs or spray over them? Which rooms get interior treatment and with what product?
Why do spider bites often turn out to be infections?
The diagnoses can overlap and the figures describe clinic patients, not the community. A red, painful, spreading sore with no spider seen deserves a doctor's look, whatever pest control you also decide to do. Because skin infections look like bites and spiders rarely bite people. In Suchard's study of 182 patients with suspected spider bites at one California emergency department between January 2006 and November 2007, published in 2011, 85.7% were diagnosed with an infection and only 3.8% with a spider bite.
How much does it cost to have a house sprayed for spiders?
Ask what the price includes and whether interior, exterior or both will be treated. It's a published estimate, not a local quote. Local quotes vary; ask for a written estimate. Many pros combine methods after an inspection.
