Spray does less than you think

Worth knowing before you buy it. Residual insecticide works by contact with a treated surface, and a spider walks on the tips of its legs — its body barely touches anything, and it does not groom itself the way a cockroach does. So a perimeter spray that is devastating to ants does comparatively little to spiders.

What actually reduces spiders in a house:

  1. Web and egg sac removal. Physically knocking down webs at eaves, soffits, window frames, porch ceilings and garage corners, and removing egg sacs. This is most of what a visit is worth and it is immediate.
  2. Exclusion. Door sweeps, window screens, sealing where pipes and cables enter, and the gap under the garage door. Spiders come in; stopping them coming in works.
  3. Taking away their food. Everything below.
  4. De-cluttering garages, basements and crawl spaces, which is where the spiders people worry about actually live.

A treatment that is only a spray is the weakest version of this job. One that includes web knock-down and a look at the entry points is worth paying for.

Spiders are a symptom of insects

A spider is in your house because there is something to eat. Remove the food and the population falls without any insecticide at all.

The practical interventions, in order of how much difference they make:

The two that actually matter

Almost every spider in a US house is harmless and is doing you a small favor. Two species are medically significant:

Black widow. Glossy black, round-bodied, with the red hourglass underneath. Widespread across the southern and western US. Lives in dark undisturbed places — under outdoor furniture, in woodpiles, in garage corners, in the rims of plant pots and in crawl spaces. Bites are rare and are usually the result of reaching into somewhere unseen. A bite needs medical attention.

Brown recluse. Uniform tan to brown with a darker violin shape on the back, and six eyes in three pairs rather than eight — which is the identification that actually works. Its range is the south-central US: broadly Kansas and Missouri down through Oklahoma, Arkansas, Texas, Louisiana and across to Georgia. Outside that range, reported recluse sightings are nearly always something else. A suspected recluse bite needs medical attention.

Everything else — house spiders, cellar spiders, wolf spiders, jumping spiders, orb weavers — is harmless. Wolf spiders are large, fast and frightening and are the usual cause of a panicked call; they are not dangerous. Cellar spiders (the long thin ones) eat other spiders, including the two above, which is an argument for leaving the ones in the garage alone.

Gloves in the garage, and shake out stored shoes and gardening gloves. In widow and recluse country, that is the whole of the sensible precaution.

What a visit costs

1,800 sq ft house
Quarterly plan, per visit $115
One-time treatment $140
One-time, heavy $225
Monthly plan, per visit $60

Spiders are usually treated on general pest service rather than as a specialty, which is what these figures are: a perimeter band, web removal, eaves and entry points, and interior work only where something has been seen. Compare plans on the annual total rather than the per-visit figure — four quarterly visits come to roughly what six or seven monthly visits do.

Quarterly suits most houses. The seasonal pattern is worth knowing: spider activity indoors peaks in late summer and fall, when males wander looking for mates, so a visit timed for late August does more than one in March.

What not to pay for

Worth doing yourself, and it costs nothing: knock the webs down. A long-handled brush around the eaves and porch ceilings once a month in the fall is genuinely effective, and it is most of what you would be paying somebody for.

Questions worth asking

Common questions

How much does spider control cost?

About $115 a visit on a quarterly plan for an 1,800 square foot house, or $140 for a one-time treatment and $225 if the infestation is heavy. Spiders are normally handled on general pest service rather than as a specialty, so if a company prices spider control at a premium over general service, ask what is different about it.

Does spraying work for spiders?

Less than people expect. Residual insecticide works by contact with a treated surface, and a spider walks on the tips of its legs with very little body contact, nor does it groom itself the way a cockroach does. So a perimeter spray that is devastating to ants does comparatively little to spiders. What works is web and egg sac removal, exclusion at doors and windows, and reducing the insects the spiders are eating.

What actually gets rid of spiders?

Four things, in order: knocking down webs and removing egg sacs, which is immediate; exclusion — door sweeps, window screens, sealing pipe and cable entries and the garage door gap; reducing their food by moving exterior lights away from doorways and dealing with damp; and de-cluttering garages, basements and crawl spaces, which is where the spiders people worry about actually live. Insecticide is the least important of the five.

Why do I have so many spiders?

Because there is something for them to eat. Spiders follow insects, and the insects are usually following exterior lights and moisture. Fitting a warm-colored or yellow bug light, or moving the light off the wall beside the door onto a pole further away, is the single most effective change most houses can make. After that: fix damp, trim vegetation off the walls and move the woodpile away from the house.

Which spiders in the US are dangerous?

Two. The black widow — glossy black with a red hourglass underneath, widespread in the southern and western US, living in woodpiles, garage corners, under outdoor furniture and in crawl spaces. And the brown recluse — tan to brown with a darker violin marking and six eyes in three pairs rather than eight, found broadly in the south-central US from Kansas and Missouri down through Texas and across to Georgia. Both bites need medical attention. Everything else in a US house is harmless.

How can I identify a brown recluse?

By the eyes rather than the violin, which is the detail that matters: a recluse has six eyes in three pairs, where almost every lookalike has eight. It is uniform tan to brown with no banding on the legs and no pattern on the abdomen. Range matters too — it is a south-central US species, and outside that range reported sightings are nearly always something else, usually a harmless house or sac spider.

Are wolf spiders dangerous?

No. They are large, fast, hairy and alarming, which is why they cause most panicked calls, but they are not medically significant. They are hunters rather than web builders, which is why they appear running across a floor rather than sitting in a corner, and they come indoors in the fall. Catching one under a glass and putting it outside is the whole of the required response.

Should I kill cellar spiders?

There is a decent argument for leaving them. The long thin spiders in garage and basement corners eat other spiders, including black widows, so a population of them is doing useful work in exactly the places where the species you care about live. If the webs bother you, knock them down and the spiders move; a garage with no cellar spiders in it is not an improvement.

Why do I see more spiders in the fall?

Because male spiders wander looking for mates in late summer and fall, which is when they appear in the middle of floors and in bathtubs. They are not coming in from the cold — most house spiders have been there all along, out of sight. It does mean a pest visit timed for late August achieves more than one in March, which is worth asking about when scheduling a plan.

Do spider foggers or bombs work?

No, for two reasons. The aerosol does not reach into the voids, corners and undersides where spiders actually sit, and it does nothing at all about the webs, the egg sacs or the gaps they came in through. They also spread flammable propellant around a house with pilot lights in it. A long-handled brush around the eaves once a month in the fall is more effective than any fogger.

Can I do spider control myself?

Most of it, yes, and it is the pest job where DIY comes closest to professional results. Knock down webs and egg sacs with a long-handled brush around eaves, porch ceilings, window frames and garage corners once a month in the fall; fit door sweeps and fix screens; change the exterior lighting; and keep the garage and basement tidy. What a professional adds is reach at height, a perimeter treatment that suppresses the insect population, and somebody who recognizes a widow when they see one.

What should I do about spiders in the garage?

Accept some, and take the sensible precaution: wear gloves when moving stored items, shake out shoes and gardening gloves that have been sitting, and keep boxes off the floor and away from the walls. Garages are ideal spider habitat — undisturbed, sheltered and full of insects — and the realistic goal is management rather than elimination. In widow and recluse country that precaution is the whole of what is needed.
