A compiled reference of 44 verified statistics on pests in restaurants: how large a share of health violations are pest related in New York City, Chicago, Boston and Los Angeles County (computed by us from each city's open inspection data for the year to August 2026). It also covers which pest inspectors find most, how pest findings track with closures and grades, the FDA Food Code sections behind every pest citation, what diners say they do after a sighting, what operators fear most, and what a commercial pest contract costs in 2026. Every figure is drawn from a named public source (the four health departments' datasets, the FDA, Orkin, Terminix, a Cebr study for Rentokil, the CDC, and 2026 price guides) and independently checked before publishing.

Key statistics

Key takeaways

Pests are not a rare finding. In the four biggest open inspection datasets, between one in eight and one in three restaurant inspections records live pest evidence, and pest citations rank in the top four in New York City, Chicago and Boston. Three of four NYC closure orders and 63 of 64 LA County grade losses carried one. Diners punish sightings harder than inspectors do.

NYC has a separate code for each pest, so its bar sums to 100%. Boston and Chicago record one pest item and describe the pest in a free-text comment, so their bars show the share of comments that name each pest; a comment can name more than one, and the grey remainder is comments that named none of the three. Rodents are the most common named pest in every city.

How we built this report

Every figure was compiled in September 2026. Groups 1 to 4 are our own computations from open government data; the rest are quoted directly from named public sources and checked against the original before publishing.

  1. Pulled the raw inspection records

    New York City (dataset 43nn-pn8j) and Chicago (4ijn-s7e5) through their Socrata APIs, Boston through its CKAN datastore SQL endpoint, and Los Angeles County's inspection and violation CSV files from its ArcGIS open data items, joined on the inspection serial number. Window: inspection dates 2025-09-01 to 2026-08-31, except LA County, which publishes fiscal-year files (2025-07-01 to 2026-06-30).

  2. Counted pest codes against every violation

    Example NYC query: $select=violation_code,count(*)&$where=inspection_date between '2025-09-01T00:00:00' and '2026-08-31T23:59:59'&$group=violation_code. Inspections are distinct establishment-and-date pairs (NYC count(distinct camis||inspection_date); Boston licenseno||resultdttm). Chicago stores all violations in one text field, so we split it on the pipe separator and matched item numbers. LA County changed its code list mid-year, so old and new codes for the same item were combined.

  3. Read the inspector comments for pest type

    Where a city has one pest item (Boston, Chicago), we searched only the comment text for rodent, fly and roach terms. NYC has a code per pest, so no text matching was needed.

  4. Quoted surveys and the rule book verbatim

    Orkin, Terminix and Cebr survey figures, the FDA Food Code sections, CDC guidance and price guides are each quoted as the source states them, with the year and sample size where the source gives one.

  5. Independent review

    Written by one co-founder, reviewed by the other before publishing.

Read our full editorial process

Scope caveat: the city figures count what inspectors wrote down, not how many pests exist. Inspection frequency, code definitions and enforcement culture differ by city, so a higher share does not mean a dirtier city. The datasets are live and get corrected, so a re-run will drift by a small amount. Survey figures are self-reported attitudes, mostly from pest control companies' own polls, and Orkin's 2014 report does not publish its sample size. Price guides are national or single-market ranges, not quotes.

Restaurant pests, by the numbers

All 44 figures, grouped by theme. The first four groups are computed from open data (gold badge); the rest are verified against the named source (blue badge).

New York City: pests in 1 of every 10 violations

New York City publishes every violation from every inspection, with a separate code for each pest. According to the NYC Department of Health and Mental Hygiene's restaurant inspection open dataset (nyc.gov), as computed by RapidEye Research, inspectors cited 97,038 violations across 27,501 inspections at 20,628 establishments between September 2025 and August 2026. Live pest evidence (mice, rats, roaches, or flies and other nuisance pests) accounted for 9,942 of those citations, and the harborage code 08A for another 7,757, the second most-cited code in the city behind unclean non-food surfaces (13,702).

Statistic 1

In New York City, 9,942 of the 97,038 violations cited between September 2025 and August 2026 (10.2%) were for live pest evidence: mice, rats, roaches, or flies and other nuisance pests.

Computed

Statistic 2

Code 08A, conditions conducive to pests, was New York City's second most-cited violation with 7,757 citations (8.0% of all violations); pest evidence plus pest conditions together made up 18.2% of everything inspectors wrote up.

Statistic 3

8,096 of New York City's 27,501 restaurant inspections in the window (29.4%) recorded at least one live pest evidence code, touching 6,580 of the 20,628 establishments inspected (31.9%).

Computed

Statistic 4

Mice were the pest New York City inspectors found most often: evidence of mice was cited in 4,190 inspections (15.2%), flies or other nuisance pests (code 04N) in 3,318 (12.1%), roaches in 1,521 (5.5%), and rats in 895 (3.3%).

Computed

Statistic 8

New York City inspectors wrote 867 citations for having no pest management contract or extermination records on file (code 28-06).

RapidEye Research analysis of NYC DOHMH open data (2026)

Computed

What this means: Nearly a third of NYC inspections find a live pest, and every such finding is automatically Critical. Pests are also the common thread in closures: three of every four closure orders carried one. For an operator, the 7,757 harborage citations are the leading indicator; they are the conditions an inspector sees before the pest appears, and they are the ones a routine documented walkthrough can catch first.

Chicago: item 38 on half of all failed inspections

Chicago records every inspection as one row with all violations in a single text field, numbered by the FDA Food Code inspection form. According to the Chicago Department of Public Health's food inspections open dataset (chicago.gov), as computed by RapidEye Research, item 38 ("insects, rodents, and animals not present") was the fourth most-cited item in the year to August 2026, behind physical facilities (item 55), surface design and construction (item 47) and unclean non-food contact surfaces (item 49).

Statistic 9

In Chicago, inspection item 38 (insects, rodents and animals not present) was cited 2,995 times, 6.3% of the 47,780 violation items recorded between September 2025 and August 2026, making it the city's fourth most-cited item.

Statistic 13

Inspector comments on Chicago's item 38 citations mentioned rodent terms (mice, rats, or droppings) in 1,054 cases (35.2%), flies in 454 (15.2%), and roaches in 292 (9.7%).

RapidEye Research analysis of Chicago CDPH open data (2026)

Computed

What this means: Chicago's pest share of violations (6.3%) looks modest next to NYC's, but the item shows up on half of all failures. A pest finding is rarely the only problem on a failed report; it travels with the sanitation and facility items that precede it.

Boston: pest control is the most-cited violation

Boston cites pests under the Massachusetts food code's adoption of FDA section 6-501.111. According to the City of Boston Inspectional Services food establishment inspections open dataset (boston.gov), as computed by RapidEye Research, "Controlling Pests" was the most-cited violation in the city in the year to August 2026, edging out unclean non-food contact surfaces (1,798) and floors, walls and ceilings (1,692).

Statistic 14

In Boston, "Controlling Pests" was the single most-cited violation between September 2025 and August 2026: 1,804 priority-foundation citations plus 655 core citations, 2,459 in all, 5.1% of the 47,862 violations recorded.

Statistic 15

Adding Boston's 880 "Outer Openings Protected" citations (the pest-entry rule) brings pest-related violations to 3,339, or 7.0% of the total.

Statistic 18

64 of the 154 Boston inspections that ended in a voluntary closure (41.6%) included a Controlling Pests citation.

RapidEye Research analysis of City of Boston ISD open data (2026)

Computed

What this means: Boston is a rodent city on paper: two of every three pest citations describe mice, rats or droppings. That is the pest most likely to be found by looking rather than by luck, since droppings and gnaw marks persist between visits. A regular photo record of storage areas and floor edges can surface them before the inspector does.

Los Angeles County: pests decide the grade

Los Angeles County grades every inspection on a 100-point scale and posts a letter. According to the Los Angeles County Department of Public Health's Environmental Health inspection and violation open data (publichealth.lacounty.gov), as computed by RapidEye Research, pests present was cited in 11.9% of the 28,511 inspections in fiscal year 2025-26, and the inspections that found pests graded far worse than the rest.

Statistic 19

In Los Angeles County's fiscal year 2025-26, 3,396 of 120,235 violations (2.8%) were for insects, rodents, birds or animals present, and another 5,585 (4.6%) were for vermin-proofing failures; together 7.5% of all violations.

What this means: In a points system, a pest finding is what tips an A into a B or C. Nearly every LA County facility that fell below 70 had one. The 5,585 vermin-proofing citations (gaps, screens, door sweeps) are cheaper to fix than the pests they let in, and they are visible in a photo of the back door.

The rule book: what the FDA Food Code requires

Every city code above traces back to a handful of sections in the model code most states adopt. According to the US Food and Drug Administration's Food Code 2022 (fda.gov), the core pest provision is section 6-501.111, and the model inspection form's item 38 (the same number Chicago uses) draws on seven code sections in all. The "Pf" tag means priority foundation, one step below a priority (P) violation.

Statistic 24

FDA Food Code section 6-501.111 requires a food establishment to be kept free of insects, rodents, and other pests through four measures: inspecting incoming shipments, inspecting the premises for evidence of pests, using control methods when pests are found, and eliminating harborage conditions.

FDA Food Code 2022, Chapter 6

Verified

Statistic 25

Section 6-202.15 requires outer openings to be protected against insects and rodents in three ways: filling holes and gaps along floors, walls and ceilings; closed, tight-fitting windows; and solid, self-closing, tight-fitting doors.

Verified

Statistic 26

Section 6-501.112 requires dead or trapped birds, insects, rodents and other pests to be removed from control devices and the premises often enough to prevent accumulation, decomposition, or the attraction of more pests.

FDA Food Code 2022, Chapter 6

Verified

Statistic 27

The Food Code's model inspection form item 38, "Insects, rodents and animals not present," draws on seven code sections, including animal handling (2-403.11), insect control device placement (6-202.13), outer openings (6-202.15), exterior walls and roofs (6-202.16), controlling pests (6-501.111), removing dead pests (6-501.112) and prohibiting animals (6-501.115).

FDA Food Code 2022, Annex 7

Verified

What this means: Two of the four duties in 6-501.111 are inspection duties: look at what comes in, and look at the premises for evidence. The code expects the operator, not the health department, to be the first inspector. A dated record of those checks is also the defense when a citation is contested.

What diners do after a sighting

The most-quoted numbers in this field come from one document. According to Orkin's restaurant industry insights survey report (orkin.com), published in 2014, half of patrons saw a pest at a restaurant in the past 12 months and 81% would never return after a pest on their plate. Orkin does not publish the sample size for that survey; its earlier 2006 poll of frequent diners does (267 of 410 respondents).

What this means: Diners see flies most and forgive flies most; they punish roaches and anything on the plate. Only 8% call the health department, so the inspection record understates what customers are seeing, and the review sites carry the rest.

What operators report

Two business-side surveys fill in the operator view. According to Terminix Commercial's 2018 pest perceptions survey release (terminix.com), a 2018 survey of 900 pest control decision-makers, 78% of business leaders with pest control in place are confident their facilities are pest-free, yet 65% still feel vulnerable. And according to a Centre for Economics and Business Research study for Rentokil (rentokil.co.uk), based on a January 2015 survey of 210 US decision-makers, 90% of US businesses had at least one infestation in five years.

What this means: Confidence and vulnerability coexist because most operators have no independent picture of their own back-of-house between contractor visits. The inspection data is the outside view: even with a contract being the norm, a live pest turns up in roughly one NYC inspection in three and one Boston inspection in five.

Health stakes and what control costs

The health case is why pest citations are Critical. According to the Centers for Disease Control and Prevention's rodent control guidance (cdc.gov), rodents spread 13 listed diseases directly, salmonellosis among them, and more indirectly through fleas, ticks and mites. On price, Housecall Pro's 2026 pest control pricing guide (housecallpro.com) puts commercial work at $150 to $400 per visit, and a New York City pest control company's 2026 cost guide (advancedexterminating.com) lists monthly restaurant programs from $100 to $800 depending on volume.

Claims we could not verify

Three figures circulate widely on pest control blogs. We traced each to its origin where we could and dropped the rest.

"97% of consumers would avoid a restaurant after reading a negative review about pests or cleanliness," attributed to the National Restaurant Association. We found it only on pest control company blogs, never in an NRA document. Orkin's 2014 report does contain a different 97% (patrons naming at least one pest encounter that would make them never return), which is the likely source of the mix-up. Not on this page.

"59% of customers won't return to an establishment where they saw a pest," attributed to NPMA. No NPMA or PPMA release or survey page carries it; pestworld.org's food service page has no percentages at all. Not on this page.

"50% of diners saw a pest" and "81% will never return." Both are real and both come from Orkin's 2014 restaurant industry insights (quoted in Group 6). The report does not disclose its sample size or field dates, and the 28.5% cockroach figure often cited alongside them is a separate 2006 Orkin poll of 267 frequent diners. Cite them as Orkin 2014 and Orkin 2006 respectively, not as NPMA or industry-wide figures.

Quick FAQ

What percentage of restaurant health violations are pest related?

It depends on how the city codes pests. In New York City, live pest evidence (mice, rats, roaches, or flies and other nuisance pests) was 10.2% of all violations cited from September 2025 to August 2026, and 18.2% once conditions conducive to pests are included. In Chicago the pest item was 6.3% of violation items, in Boston pest control plus outer openings was 7.0%, and in Los Angeles County pests present plus vermin-proofing was 7.5%. RapidEye Research computed all four from the cities' open inspection data.

How many restaurants get cited for mice or rodents?

In New York City, evidence of mice was cited in 4,190 inspections (15.2% of 27,501) in the 12 months to August 2026, and rats in 895 (3.3%). Mice were the most common pest inspectors found. In Boston, inspector comments on pest citations mentioned rodents or droppings in 66.4% of cases. In Los Angeles County, 11.9% of inspections found insects, rodents, birds or animals present.

What percent of diners will never return after seeing a pest?

81% of patrons say they will never return if they see a pest on their plate or food, and 76% if they see multiple pests anywhere in the restaurant, according to Orkin's 2014 restaurant industry insights survey. The same survey found half of patrons saw a pest at a restaurant in the past 12 months, and 95% of those sightings included flies. An earlier 2006 Orkin poll of 267 frequent diners found 28.5% would never return after a cockroach sighting.

How much does pest control cost for a restaurant?

Housecall Pro's 2026 pricing guide puts typical commercial pest control at $150 to $400 per visit, with food service priced custom, and works an 1,800-square-foot restaurant on a quarterly plan out to $180 per visit or $720 a year. A New York City pest control company's 2026 guide lists $100 to $300 per month for a small restaurant or cafe, $200 to $500 for a full-service restaurant, and $300 to $800 for a high-volume kitchen or bar on bi-weekly service.

What does the FDA Food Code require for pest control in restaurants?

FDA Food Code section 6-501.111 requires the premises to be kept free of insects, rodents and other pests by inspecting incoming shipments, routinely inspecting the premises for evidence of pests, using control methods such as traps when pests are found, and eliminating harborage conditions. Section 6-202.15 requires outer openings to be protected with sealed gaps, tight-fitting windows and solid self-closing doors. Section 6-501.112 requires dead or trapped pests to be removed before they accumulate.
