Pest Pressure Index for Greater Orlando

What is the Pest Pressure Index?

The Pest Pressure Index (PPI) compares the last 7 days of temperature, humidity, and rainfall in each city to about 3 years of local history, using validated weather data sources*. Scores run from 0 to 100. Higher values mean recent weather looks more like the warm, wet stretches when mosquitoes, ants, and similar pests pick up outdoors. 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. You will see a Greater Orlando average on the homepage and a separate score on each city page.

What raises and lowers the score

We weight three inputs by how strongly they track outdoor pest activity in Central Florida. Scores climb fastest when all three run high together after storms or muggy stretches. They ease when the week lands milder for that city's own history.

• Temperature (35%): warmer-than-usual weeks speed insect activity.
• Humidity (30%): sticky air favors roaches, mosquitoes, and ants along foundations and beds.
• Rainfall (35%): heavy or frequent rain fills drains, saucers, and mulch lines.
• Typical High weeks: back-to-back storms, warm nights, tropical moisture, or late-summer rainy stretches.
• Typical Low weeks: drier spells, lighter showers, or short breaks when gutters and beds stay drier.

How to read Low, Moderate, and High

Low (under 40), Moderate (40 to 69.9), and High (70 and above) describe the last week against that city's recent norm. Treat Low as routine exterior maintenance weather. In Moderate weeks, walk the perimeter after rain. In High weeks, dump standing water and check mulch along the foundation. PPI tracks weather trends only. It will not tell you whether roaches are active inside tonight. Sanitation, landscaping, and how your home is sealed matter just as much.

How we use PPI

On site, we factor PPI into follow-up timing and exterior work after heavy rain. A High week may mean extra attention on drains and entry points. A Low week still gets the same inspection-first visit.

• We track metro PPI to anticipate inbound call volume when several cities move into Moderate or High after rain and heat.
• That helps us staff phone and dispatch on busy weeks so wait times stay reasonable.
• PPI is a weather signal for planning outdoor and perimeter work. Indoor activity still needs a look at harborage, food, and moisture inside the structure.
