How we pick

We don't run a test lab. Every pick here is chosen by reading the manufacturer's own specs, the pattern in thousands of verified buyer reviews, and published guidance from university extension entomologists — and by ruling out the products whose marketing claims don't survive that reading. Where the evidence says a whole product category doesn't work, we say so.

That paragraph is the whole method. The rest of this page is the detail.

What we look at

Mechanism of action. How does the product actually kill or repel the animal? This is the first filter and it removes more products than anything else. A device whose stated mechanism does not match how the pest finds you is not a borderline pick, it is a wrong one — which is why ultraviolet light scores badly for mosquitoes and a CO2 lure scores well.

Stated coverage or capacity. The manufacturer's own number, reported as theirs. When we write "manufacturer states up to 1 acre", that phrasing is deliberate: it is their claim, made under ideal conditions, and we are passing it on rather than endorsing it.

Running cost. Refills, cartridges, propane, bulbs, glue boards, batteries. This is where the cheap product often turns out to be the expensive one, and it is routinely missing from other roundups. Every pick on this site names its consumables.

Safety design around pets and children. Not whether the box says pet-safe, but whether the mechanism is physically enclosed. A trap that is only safe because of where you put it is not a pet-safe product, it is a plan.

Whether it is currently sold. A roundup full of discontinued models is worthless. Every product here was a current model at the date on the page.

What we rule out

• Products whose marketing claim contradicts published entomology. Ultrasonic rodent repellers are the standing example; extension testing does not support the claim on the box.
• Products with a documented secondary-poisoning risk where a safe alternative does the same job. Anticoagulant rodenticides fail this test almost every time, because a trap in a locked station does the same job without poisoning whatever eats the rodent afterward.
• Discontinued products, however well they used to work.
• Products we cannot describe honestly — where the only available information is the brand's own marketing copy and there is no independent pattern to read.

What we will never do

• Claim to have tested something. We have not. No "in our testing", no "after eight weeks", no lab.
• Publish a rating or a review count we cannot source. There are no star ratings on this site.
• Publish a price we cannot pull live from the retailer. Every buy button currently reads "Check price on Amazon" for exactly this reason — a stale price is worse than no price.
• Invent a credential. Ryder M. is the hands-on owner behind Magoo Media Group, and nothing more is claimed.

Where the evidence comes from

In order of weight:

1. University extension services and public health agencies — UF/IFAS, UC IPM, Penn State Extension, Iowa State Extension, the CDC and the EPA. Free, authoritative, and mostly absent from competing roundups. Where a claim on this site rests on evidence, this is where it comes from and we link the document.
2. Manufacturer specification sheets, for mechanism and coverage only — never for efficacy.
3. The pattern across large volumes of verified buyer reviews, reported qualitatively. "Buyers consistently report the contacts fouling" is a claim we will make. "4.6 stars from 12,000 buyers" is not, because we cannot verify the number.

Anything that cannot be traced to a primary source does not go on the page. A widely-repeated statistic about bug zappers — the "71% / 7%" figure attributed to the University of Florida — is a worked example: we could not trace it to any primary document and the attribution appears to be wrong, so it appears nowhere on this site. The verified UF/IFAS quote is used instead.

How commission affects the picks

It does not, and there are two pages that demonstrate it rather than assert it.

The bug zapper roundup links to bug zappers and opens by telling you they barely work on mosquitoes. The pet-safe rat poison page answers a high-intent shopping query by explaining why you should not buy the product you searched for.

Both pages would earn more if they were written the other way. Full detail on the funding model is on the affiliate disclosure page, and the corrections process is in the editorial policy.

When we tell you to stop

This site exists so you can handle a pest problem yourself. It should therefore be clear about the cases where you should not: a structural rat colony inside a wall, a large droppings clean-up in an unventilated space, a repeat infestation that returns within weeks of every treatment, or any situation involving someone immunocompromised in the household. Every pillar guide on the site carries that section.
