Select your product, application type, and sprayer size. Get the exact amount of concentrate to measure — with step-by-step mixing instructions. All rates are based on published EPA-registered labels.
Pesticide labels give a rate like "0.5 fl oz per gallon." Here's what that actually means and how to scale it up for any tank size:
| EC | Emulsifiable Concentrate — liquid, mixes with water to form milky emulsion |
| SC / CS | Suspension Concentrate / Capsule Suspension — tiny particles suspended in liquid |
| WP | Wettable Powder — dry powder that mixes with water; often sold in pre-measured packets |
| WDG / WG | Water-Dispersible Granule — granules that dissolve when added to water |
| RTU | Ready to Use — pre-diluted, do not add water |
| REI | Re-Entry Interval — minimum time before people/pets can re-enter treated area |
| PHI | Pre-Harvest Interval — days between application and harvest (agricultural) |
All rates below are from published EPA-registered labels. Rates reflect general/perimeter applications unless noted. Always consult your specific product label — rates vary by site, pest, and formulation lot.

This guide is one entry point in a connected library. Each pest profile, treatment guide, and tool on this site links to related references that go deeper than any single page can. Working through a pest problem effectively usually means starting with identification (so you know what you're treating), reading the species-specific treatment guide, checking the product or tool references for specific selection guidance, and confirming approach with the FAQ and troubleshooting sections. Bookmarking a few core references — the species profile, the relevant treatment guide, and one tool that supports the decision-making (product selector, cost estimator, treatment schedule) — gives you a workflow you can return to as the situation evolves. The structure is intentional: surface-level summary first, then increasing depth, with the deepest detail in the dedicated tool and reference pages.
Pesticide resistance is now common enough across major pest categories — cockroaches, bedbugs, mosquitoes, certain ant species, some flies — that treatment recommendations have shifted to account for it. Resistance develops through repeated exposure to a single active ingredient class; the surviving population reproduces, and over generations the population shifts toward resistance. Slowing resistance development requires rotating active ingredient classes (not just brands), using full label rates rather than reduced rates, and avoiding routine prophylactic spraying when it isn't needed. The EPA mode-of-action (MoA) classification on product labels helps with rotation: alternating between products in different MoA classes is more effective than alternating brand names within the same class. For homeowners, the practical translation is: don't use the same product month after month; if you're spraying regularly, rotate among at least two unrelated chemistries; and don't spray when monitoring suggests no active population.
Content on this site is reviewed by Derek Giordano, a former pest control company owner and previously licensed Pest Control Operator in Florida with several years of field experience servicing thousands of regular customers. Reviews check treatment recommendations against current EPA-registered products and label use directions, cross-reference major treatment claims against university extension publications and CDC public health guidance, and verify that any product mentions reflect current registration status and reasonable consumer availability. Pages get updated as treatment recommendations evolve — pesticide products are deregistered, resistance patterns shift, regional pest distributions change. The 'Updated' date at the bottom of each page reflects the most recent review pass on that specific page; the site-wide approach to E-E-A-T (experience, expertise, authoritativeness, trustworthiness) follows Google's published guidance on health and safety topics.
Editorial sources used consistently across this site: the EPA pesticide registration database for current product use directions and active ingredient information; CDC for public health context on pest-borne disease; the National Pesticide Information Center (NPIC) for homeowner pesticide questions; university Cooperative Extension publications (UC IPM, NC State Extension, Penn State Extension, University of Florida IFAS, and others) for region-specific identification and treatment guidance; the National Pest Management Association (NPMA) for industry context; and peer-reviewed entomological literature for biology, resistance management, and emerging issues. Product reviews reflect editorial testing and aggregated user-reported outcomes rather than manufacturer-supplied claims. Where regional information matters, we link to state and local extension publications rather than generalizing across regions.
Pesticide efficacy is highly sensitive to the conditions at application and immediately after. Temperature affects both vapor pressure (volatility) and residual binding — products applied above ~90°F often volatilize before binding to surfaces, while applications below ~50°F can fail to spread properly. Surface porosity changes residual duration: a residual that lasts eight weeks on a sealed concrete slab might last three weeks on bare wood. Rainfall within four hours of an outdoor application typically washes off most surface deposits, though microencapsulated products are more rain-fast. UV exposure degrades many pyrethroids within days to weeks on sunny surfaces, which is why fence-line applications often fail mid-summer. Indoor humidity affects bait acceptance — dry baits perform worse in high humidity as they absorb moisture and lose palatability. Reading conditions correctly explains many otherwise mysterious treatment failures.
State cooperative extension services — university-based educational and advisory programs in every state — are dramatically underused resources for residential pest decisions. Most state extensions employ entomologists who answer homeowner questions free of charge through county offices, online query forms, or scheduled call hours. The information available is specific to the state's pest pressure, climate, and recommended practices, and is typically much more locally accurate than national resources. Extension publications cover identification, life cycle, treatment options, and specific product recommendations for state conditions; the publications are peer-reviewed by university scientists and updated periodically based on current research. For any pest situation where identification is uncertain or treatment options are unclear, a clear photograph submitted to the state extension produces an identification, a brief biological explanation, and one or more treatment options within typically a few days. The benefit beyond any single inquiry is building familiarity with the local resource — extension contacts become a reference for future situations and produce better decisions than aggregated online advice.
Species misidentification is the single most common reason that DIY pest treatment fails or that homeowners describe products as not working. The patterns are consistent: bed bug bites are routinely attributed to mosquitoes, fleas, or unknown causes; carpet beetle larvae are mistaken for bed bug nymphs; small black ants are called 'sugar ants' regardless of actual species; carpenter ants and termites are confused despite very different treatments; bat bugs are treated as bed bugs (the treatment may work, but the actual problem is overhead). Even when identification is correct at the family level, species within a family often require different approaches — German vs. American cockroaches, subterranean vs. drywood termites, or pavement vs. carpenter ants are practical examples. The first hour of any pest problem should go to identification, not treatment: photograph specimens with a coin for scale, send images to a local cooperative extension office (most respond within a day or two), or post to one of the moderated identification forums where entomologists answer. Correct identification narrows treatment options to those that actually work and discards the larger pile that don't.
Integrated pest management (IPM) is a structured approach to pest control developed for agricultural and commercial settings that translates well to residential use. The hierarchy: prevention first (sanitation, exclusion, habitat modification to make conditions unfavorable for pests), monitoring second (sticky monitors, visual inspection, identifying pests at low population before infestation establishes), targeted intervention third (using the least disruptive effective method against an identified pest in an identified location), and broad chemical treatment last (when targeted approaches have failed or aren't feasible). The hierarchy matters because higher-level interventions are durable and address root causes, while lower-level chemical interventions address symptoms and require repeat application. Most residential pest control reverses this hierarchy — chemical treatment first, sometimes prevention later — and produces the predictable consequence of recurring problems. Households that adopt the IPM hierarchy (often without using the term) generally describe spending less time and money on pest issues over years even though specific incidents might take more thought to address than spray-and-forget approaches.
The quality of pest information available to homeowners varies enormously by source, and finding the reliable sources for your specific region is a one-time investment that pays off across years of pest management decisions. Cooperative extension services associated with land grant universities in each state are usually the highest-quality regional resource, producing fact sheets, identification guides, and treatment recommendations specifically calibrated to local conditions, pest species, and regulatory environments. State department of agriculture pest fact sheets are typically similar in quality and orientation. Local pest control company blog content varies in quality but can be useful when produced by experienced practitioners writing about their actual work rather than generic SEO content. National pest control sites tend to be less useful for the specific reason that they average across regions and don't address the conditions you're actually facing. Bookmarking two or three high-quality regional resources at the outset, and consulting them before making significant pest management decisions, raises the average quality of your decisions dramatically without much ongoing effort.
The residual life of a pesticide is one of the most misunderstood properties in household pest management. Active ingredients vary widely in how long they remain bioavailable on a treated surface, and the same active can behave very differently depending on substrate, exposure to sunlight and rain, temperature, and the formulation it's carried in. A pyrethroid applied to a porous masonry surface in full sun will degrade in days; the same active in a microencapsulated formulation on a protected interior surface may remain effective for months. Understanding this is the difference between an evidence-based treatment schedule and one driven by superstition. Reapplying too soon wastes product and increases selection pressure for resistant individuals; reapplying too late creates gaps in coverage during which pest populations rebound. The right answer depends on specific conditions and is not the same number printed on the bottle in all circumstances. Field experience and willingness to monitor for early signs of pest return are what calibrate the schedule. The label is a guide, but conditions in front of you are the real input.
Pest forecast reports — issued by some state agricultural agencies, cooperative extension services, and commercial pest control companies — are an underutilized resource for homeowners who want to anticipate rather than react to seasonal pest activity. These reports typically combine historical pest data, current weather conditions, and growing degree day calculations to predict when specific pests will emerge or peak in specific regions. A tick forecast for an upcoming spring season, a mosquito pressure forecast after a wet winter, a termite swarm prediction for a specific week in the Southeast — these aren't speculation but reasonably calibrated predictions based on biological timing. For homeowners, the value is in scheduling preventive treatment and personal protection to match the predicted high-pressure windows rather than reacting after problems have established. Subscribing to a regional pest newsletter from a cooperative extension service or state agriculture department is free or low cost and produces these forecasts during relevant seasons. The information is dramatically more actionable than generic pest control content because it's calibrated to your specific region and current conditions.
