Two of the largest pest intelligence sources in the industry released their 2026 seasonal forecasts within a week of each other this spring. Both said the same thing. The Southeast is heading into one of the heaviest pest activity windows in recent memory, and South Florida is at the center of it.

This is not a pest control company trying to scare you into booking. These are national research organizations with decades of data backing their projections. What they are forecasting lines up exactly with what we have been seeing in the field across Palm Beach County and the Treasure Coast since March.

At a glance

At a glance

The NPMA’s 2026 Bug Barometer forecasts heightened pest activity across the Southeast, driven by a warm winter and early humid conditions. Aptive’s Spring Pest Intelligence Report, released April 2, projects elevated termite, ant, mosquito, and cockroach pressure across Florida specifically. Aptive’s 2026 Spring Pest Intelligence Report, released April 2, projects elevated termite, ant, mosquito, and cockroach pressure across Florida specifically, citing above-average soil moisture and compressed swarm timing.

South Florida’s combination of year-round warmth, persistent humidity, sandy soil, and dense residential construction places Palm Beach County and the Treasure Coast at the leading edge of both forecasts.

Homeowners who are on a prevention plan are already ahead. Homeowners who are not are running out of runway before the rainy season surge hits full stride in June.

What the NPMA Bug Barometer actually says

The National Pest Management Association publishes its Bug Barometer twice a year, projecting pest activity by region based on weather patterns, soil conditions, and historical data. The 2026 spring edition flags the Southeast for above-normal activity across multiple species categories.


NPMA’s forecast cites a warmer-than-average winter across the Southeast as the primary driver, with earlier emergence of termite swarmers, accelerated mosquito breeding timelines, and extended ant foraging seasons all projected for the spring-summer window.

For South Florida specifically, the forecast aligns with what homeowners in Boca Raton, Boynton Beach, Lantana, Port St. Lucie, and Stuart have already been experiencing. Formosan and Asian subterranean termite swarms started earlier than usual this year. Ghost ant activity ramped up in March rather than April. Mosquito breeding sites that typically become productive in June were active in May.

The NPMA does not use the word “unprecedented.” What they do say is that the conditions favor heightened activity, and the data from Florida supports that assessment.

What the Aptive Spring Pest Intelligence Report adds

Aptive Environmental’s 2026 Spring Pest Intelligence Report takes a more granular approach. Released April 2, the report uses field data from thousands of service calls across the Southeast to project species-specific activity levels for the coming season.

The Florida-specific findings are worth reading closely. Subterranean termite swarm events are running two to three weeks ahead of the historical average timing window. Ant species that typically peak in late spring are already at mid-summer activity levels. Cockroach populations in coastal and canal-adjacent areas are elevated. Mosquito breeding cycle timing has compressed, meaning populations are building faster and peaking earlier.

The report attributes the acceleration to above-average soil moisture through the winter and early spring, combined with soil temperatures that never dropped low enough to reset insect development cycles. In a state like Florida, where winter dormancy is already minimal, the practical effect is that the population baseline going into rainy season is higher than normal.

What this means for Palm Beach County and the Treasure Coast

National forecasts provide useful context. Local conditions determine what actually happens at your property. Palm Beach County and the Treasure Coast sit in the most pest-productive climate zone in the continental United States.

Year-round warmth eliminates the winter reset that northern states rely on to suppress populations. High humidity supports continuous breeding cycles for moisture-dependent species like German cockroaches, ghost ants, and silverfish. Sandy, well-drained soils accelerate termiticide degradation, shortening the effective lifespan of pre-treatment protection on newer homes. Dense residential construction with irrigation, mulch beds, and landscaping creates harborage and breeding habitat on every block.

When a national forecast projects “heightened activity” for the Southeast, the practical translation for Boca Raton, Boynton Beach, Lantana, Port St. Lucie, Stuart, Fort Pierce, and Palm City is that the baseline pressure that is already higher than most of the country gets pushed even higher.

The homeowners who feel this most acutely are the ones who are not on a prevention plan. Properties with consistent monthly treatment absorb the increased pressure because the treatment schedule was already designed for it. Properties without ongoing treatment absorb the increased pressure directly, which is why the jump from “manageable” to “infestation” happens faster this year than in a normal year.

The species to watch this season

Based on both forecasts and what we are seeing in the field, four species categories deserve the most attention across Palm Beach County and the Treasure Coast this season.
Termites Icon

Subterranean termites.

Swarm timing is ahead of schedule, and the invasive Formosan and Asian subterranean species that have established across the region are producing larger swarm events than the historical norm. UF/IFAS Fort Lauderdale Research and Education Center continues to document the accelerating spread of both species across South Florida. Annual inspection is more important this year than in any recent season.

Ant Icon

Ghost ants and white-footed ants.

Colony expansion is running ahead of the typical spring timeline. Ghost ant trails that usually appear in April kitchens were showing up in March across Boca Raton and Boynton Beach. Bait-based treatment works, but the earlier start means the treatment window is shorter before colonies reach the size where budding behavior makes elimination harder.

Mosquitoes.

The compressed breeding timeline means mosquito populations are building toward summer levels earlier than usual. Pre-season barrier treatment applied in April or May is performing well for properties that scheduled it. Properties that have not yet treated are entering rainy season without the residual protection that makes the biggest difference in June and July.

German cockroaches.

Elevated populations in the field data correlate with the above-average humidity and soil moisture readings. German cockroaches breed continuously indoors in South Florida regardless of season, but the external conditions that support cockroach populations in shared-wall communities, commercial kitchens, and high-density housing are stronger this year.

What to do about it right now

If you are on a monthly prevention plan with any reputable pest control company, your treatment schedule already accounts for seasonal variation. Communicate with your technician about any changes in activity you have noticed, particularly earlier-than-usual ant trails, termite swarmers, or mosquito pressure. That information helps the technician calibrate the treatment to what is actually happening on your property. If you are not on a prevention plan, the window to get ahead of the season is closing. Rainy season in South Florida begins in earnest in June. Populations that are already elevated from the warm spring will surge further when the daily storms provide the standing water and soil moisture that drive the breeding cycle into peak mode.

Scheduling an initial inspection and treatment before June gives you the baseline protection that makes the rest of the season manageable. Waiting until July, when the pressure is at its annual peak, means the treatment is reactive rather than preventive, and the timeline to get results is longer.

Call Wise House Pest Control
