Where we get our information.

If you ever want to verify something we've written or dig deeper than any single article can go, these are the same sources we cite. They are all free and many are searchable.

Why source quality matters more in pest control than almost anywhere else

Search "how to get rid of [any pest]" and you'll get millions of results. The overwhelming majority are one of three things: a pest control company's marketing page (every problem ends with "call us"), an affiliate listicle assembled to sell products, or AI-generated filler that recombines other low-quality pages. None of these are written by someone who has actually studied the pest.

This matters because pest control advice that's merely plausible can be actively counterproductive. Spraying a visible ant trail feels right and makes the problem worse. Throwing out a mattress feels decisive and doesn't touch the infestation. Bug bombs feel thorough and can scatter bed bugs into neighboring apartments. The intuitive answer and the correct answer diverge constantly — which is exactly why we anchor every article to primary research rather than to whatever ranks well.

The sources below are the primary research. They are written by named entomologists, reviewed by their peers, updated when the science or the pesticide regulations change, and — critically — have nothing to sell you. When something on this site disagrees with a pest control company's blog, this is why.

A quick hierarchy of pest-control sources

When you're evaluating any pest-control claim — ours included — it helps to know roughly where a source sits on the reliability ladder:

1. Peer-reviewed entomology journals — the underlying science. Dense, but definitive. This is where claims about efficacy, resistance, and life cycles ultimately originate.
2. University cooperative extension publications — peer-reviewed research translated into practical guidance, authored by named faculty. For most homeowner questions, this is the highest-value tier you'll actually read.
3. Federal agency guidance (EPA, CDC, NPIC) — authoritative on pesticide regulation, label law, and public-health vectors. Less granular on day-to-day technique.
4. Trade publications — written for professional applicators. Technically solid, but framed around billable service rather than DIY.
5. Independent consumer guides — quality varies enormously. Good ones (we aim to be one) cite tiers 1–3 openly. Poor ones cite nothing.
6. Company marketing pages and affiliate listicles — treat as advertising, because that's what they are.

You don't need to read tier 1 to make good decisions. But knowing the ladder exists makes it obvious when a confident-sounding article is actually sitting on tier 6.

University cooperative extension

Land-grant universities maintain extension services that publish peer-reviewed, regularly updated pest management guidance for the public. These are our most-used sources.

• UC Statewide IPM Program — California, but its pest-by-pest pages are nationally relevant. Particularly strong on ants, urban pests, and Argentine ants.
• Penn State Extension — Pests — Strong on Eastern U.S. structural pests including carpenter ants, termites, and stink bugs.
• Texas A&M AgriLife Extension — Authoritative on Southern pests: fire ants, cockroaches, ticks, and termites in high-pressure climates.
• Cornell Cooperative Extension — Northeast focus. Excellent on tick-borne disease and seasonal residential pest pressure.
• University of Minnesota Extension — Insects — Upper Midwest. Strong on cold-climate pest cycles and Asian jumping worms.
• Purdue Entomology Extension — Bed bug research from Mike Potter's lab is foundational.
• University of Arkansas — Extension Entomology — Brown recluse spider research and ID.

Federal agencies

• EPA — Safer Pest Control — Federal pesticide registration database, label search, and consumer guidance.
• National Pesticide Information Center (NPIC) — EPA-funded helpline and database for pesticide questions. Operated by Oregon State University.
• CDC — Pests Around the Home — Public-health framing for vectors and stinging insects.
• CDC — Ticks — Definitive resource on tick-borne disease prevention, removal, and identification.
• CDC — Mosquitoes — Vector control, repellent guidance, and arboviral disease surveillance.

Identification & databases

• BugGuide.net — Volunteer entomologist community for arthropod identification. Submit a photo, get an ID. Sourced through Iowa State.
• iNaturalist — General biodiversity ID with strong arthropod coverage and an active community.
• UF Featured Creatures — University of Florida's peer-reviewed encyclopedia of arthropods.

Trade and professional

• National Pest Management Association — Industry trade group. Their consumer pest library is useful, though framed from a service-provider perspective.
• PCT Magazine — Trade publication for professional pest control. Articles are written for practitioners and often more technical than consumer content.

Research journals

For the underlying research:

• Journal of Economic Entomology — Peer-reviewed research on insects of economic importance. Many open-access articles.
• Journal of Medical Entomology — Disease vectors, ticks, mosquitoes, and bed bugs.
• Journal of Integrated Pest Management — Open-access IPM research.

Regulatory references

• EPA Pesticide Product Label System — Look up the full label for any registered U.S. pesticide product.
• State pesticide regulatory agencies — Where to verify applicator licenses, file complaints, and check state-specific restrictions.

How to read an extension publication

If you're new to extension publications, the format may look unusual. A useful pattern to know:

• Publications are usually authored by named faculty entomologists (so the credentials are checkable).
• Most have a "last reviewed" date — pay attention to it, since active-ingredient registrations change.
• Pesticide recommendations are tied to specific products available at the time of publication. The recommended class (e.g., "non-repellent termiticide") matters more than the specific brand named.
• Photos are usually authoritative for ID purposes — far better than stock photo libraries.

One more habit worth building: when an extension page says something different from what you expected, that gap is usually the most valuable part. Extension authors have no incentive to tell you a comforting story. If a publication says ultrasonic repellers don't work, or that a "natural" remedy is ineffective, or that a problem genuinely needs a licensed professional, that's the unvarnished version — and it's worth more than a dozen pages that tell you what you hoped to hear.

How to find your own state's extension service

Every U.S. state has a land-grant university with a cooperative extension service, and most counties have a local extension office. Your state's service will have guidance tuned to your specific climate, pest species, and pesticide regulations — which can differ meaningfully from a national average.

To find yours, search for "[your state] cooperative extension entomology" or visit the USDA's directory of the Cooperative Extension System. Many county offices also offer free or low-cost insect identification — if you can capture a specimen, this is often faster and more reliable than any photo-based tool, including ours.

When to stop reading and call someone

Research has limits. A few situations warrant a licensed professional regardless of how much you've read:

• Termites with active structural involvement — soil treatment and baiting around a foundation are not realistic DIY projects, and most mortgage lenders require a licensed inspection regardless.
• Stinging-insect nests near entryways or in wall voids — the risk of a defensive swarm outweighs the cost of a single professional visit, especially for anyone with a sting allergy.
• Bed bugs in multi-unit housing — effective control usually requires coordinated treatment of adjacent units, which a single tenant cannot arrange.
• Wildlife in the structure — raccoons, bats, and squirrels involve protected-species law, disease exposure, and roof-level work; most of this is regulated and best left to licensed operators.

Even then, the reading isn't wasted. Knowing the biology and the standard treatment approach is exactly what lets you tell a thorough quote from a padded one, and a competent operator from a salesperson.
