Pest Pressure Index for Greater Orlando

What is the Pest Pressure Index?

The Pest Pressure Index (PPI) is a weather score we publish for Greater Orlando service areas. It looks at temperature, humidity, and rainfall over the last 7 days and compares that stretch to about 3 years of local history. The number runs from 0 to 100. Higher scores mean recent weather has looked more like the warm, wet stretches when mosquitoes, ants, and similar pests pick up outdoors. Use it when you are deciding whether to tighten up exterior prevention this month.

How we calculate your score

For each city we average daily temperature and humidity and total rainfall over the last 7 days. Open-Meteo supplies the raw weather near that city's coordinates. We compare those values to roughly 3 years of trailing 7-day windows for the same place, then scale the result from 0 to 100. All three bands are scaled to about three years of weather in each city we track. Low means the last month was milder than usual for that city. Greater Orlando stays warm and wet enough that mosquitoes, ants, and moisture pests can stay active in every season. If the score lands near 100, the last week was unusually warm, humid, or wet for that city. Near 0 means the opposite. We update the numbers weekly.

What raises pest pressure on the index

PPI goes up when the last 7 days sit at the high end of what we normally see for that city. We combine three weather inputs, weighted by how strongly they track outdoor pest activity in Central Florida:

• Temperature (35% of the score): a warmer-than-usual week speeds up insect development and keeps pests active longer each day.
• Humidity (30% of the score): sticky, humid stretches favor roaches, mosquitoes, and ants along foundations and shaded beds.
• Rainfall (35% of the score): frequent or heavy rain fills drains, saucers, and mulch lines, which adds mosquito breeding sites and ant trails after storms.

Weather patterns that usually push scores up

Any one factor can lift PPI. The score jumps fastest when all three run high together.

• Back-to-back afternoon storms with little time for standing water to dry.
• Warm nights in the 70s with daytime highs above the city's recent average.
• Weeks of high humidity after tropical moisture moves through.
• Late-summer rainy season stretches across Greater Orlando cities.

What lowers pest pressure on the index

PPI drops when the last 7 days land on the mild side for that city's own history. That can still feel warm and humid by northern standards. Central Florida rarely gets a true off-season.

• Temperature: a stretch of days that run cooler than the city's recent norm (still often in the 70s and 80s).
• Humidity: drier air for several weeks, or fewer muggy mornings than usual.
• Rainfall: less total rain across the week, with fewer daily downpours.

When you might see a Low or Moderate band

A Low band (under 40) means the last week was quieter compared to that city's last few years. Moderate (40-69.9) is a typical active stretch for the region.

• A dry spell between cold fronts, with lighter afternoon showers than normal.
• Early spring or late fall windows when heat and rain both ease slightly for that city.
• Short breaks in the rainy season when gutters and beds stay drier for a week or two.

How to read Low, Moderate, and High

Scores fall into three bands: Low (under 40), Moderate (40 to 69.9), and High (70 and above). Treat Low as routine exterior maintenance weather. In Moderate weeks, walk the perimeter after rain. In High weeks, dump standing water and check mulch and shrub contact along the foundation.

Greater Orlando average vs your city

You will see a Greater Orlando average on the homepage and a separate score on each city page. Lake Mary can run drier than Orlando. Winter Park may sit in a different band than the metro average. If you are planning service, start with your city page.

What PPI does not tell you

PPI tracks weather trends. It will not tell you whether roaches are in the kitchen tonight. Sanitation, landscaping, and how your home is sealed matter just as much. When something is active inside, schedule an inspection.

Sources and updates

Weather data comes from Open-Meteo (CC BY 4.0). We run the same formula every week and write the short summaries on city pages. When a refresh is late, the city widget notes that the data may be stale.

How we use PPI in prevention-first plans

We use PPI in two ways: on your property and behind the scenes in our office. On site, we glance at the score when we schedule follow-ups or talk about exterior work after heavy rain. A High week might mean extra time on drains and entry points. A Low week still gets the same inspection-first visit. We tell you what we find before recommending anything.

• Operations: we track PPI across Greater Orlando to anticipate inbound call volume. When several cities move into Moderate or High after rain and heat, more homeowners and businesses tend to call or schedule at once.
• Staffing: higher metro scores help us add phone and dispatch coverage on busy weeks so wait times stay reasonable.
• Honest limits: PPI is a weather signal, not a count of your calls. We use it to plan capacity, not to guess what is happening inside your home.
