Who This Is For
This page is for Ontario homeowners, real estate agents, and anyone in the Ontario area dealing with a termite problem or wanting to prevent one.
The Problem
Ontario's semi-arid climate — with humidity averaging 53% and annual rainfall around 15 inches — creates conditions where termites can breed and spread efficiently.The city's reputation as Ontario International Airport, logistics hub means a steady flow of people and goods, which can contribute to pest movement and introduction.The urban nature of Ontario, combined with older housing stock and seasonal weather patterns, means termites can become a problem quickly.The Formosan subterranean termite is especially destructive along the Gulf Coast.
Warning Signs
- •Property damage such as gnaw marks, stained surfaces, or damaged materials.
- •Unexplained bites, rashes, or skin irritation, especially after sleeping.
- •Sounds in walls, ceilings, or crawl spaces — scratching, scurrying, or buzzing.
- •The March-May swarm season brings increased pest sightings, with the South experiencing them earlier due to warmer temperatures.
- •Nests, webs, burrows, or mounds on or near the property.
