As the leaves drop from the trees and cooler temperatures set in this November in St. Louis, it is easy to think that pest issues are behind us until spring. Unfortunately, this is quite the opposite with termites. When fall rolls around, these pests do not vanish with the calendar page. Termite colonies remain active with their insatiable appetites deep into the winter months, resulting in approximately $5 billion in property damage annually in the U.S. St. Louis homeowners experience mild autumn weather, which creates excellent conditions for these subtle destroyers to live under their floors and inside their walls.
Impressive termite nests are often hidden away in surprising places, and many homeowners only realize the full extent of the damage after months of activity during what they thought was the ‘off-season’. Whether you suspect you may have termites or want to confirm, pointepestcontrol.com can help protect your most significant investment.
How St. Louis’ Climate Affects Termite Activity in Late Fall
November temperatures are still between 40 and 55 degrees, according to the National Weather Service, well above the levels that would cause termites to go completely dormant. The type of termites that we most commonly see in our part of the country, subterranean termites, will be active as long as the ground temperature does not sink below the freeze line. Additionally, the Gateway City is situated directly along the Mississippi River, which contributes to the high humidity levels that are conducive to termite growth. Although their activity slows down compared to the summer months, these pests continue to tunnel through soil and feed on wood into November. This time of year, the foundation of your home, which harbours heat from your indoor heating systems, becomes a prime target.
Why Late-Season Termite Inspections Are Crucial
- Hidden damage becomes visible: Structural harm is far easier to identify and precisely quantify after an entire season of potential action.
- Preparation prevents spring swarms: Finding colonies now allows them to be treated before too many swarmers (the start of a new infestation) form in the spring
- Treatment works better in cooler weather: Termites cluster closer together in the fall, making it easier for targeted treatments to reach whole colonies.
- Insurance and real estate considerations: Most home insurance companies require annual or semi-annual inspections. If you plan on selling, addressing problems promptly will prevent deal-breaking surprises in buyer appraisals.
Preventive Measures for November Termite Control
1. Moisture Management Around Your Property
Ensure your gutters and downspouts are positioned at least three feet away from your foundation. Before winter hits, also ensure that outdoor faucets are not leaking, and search the basement for standing water (which could indicate a leak). According to the Missouri Department of Conservation, termites obtain the moisture they need because the clay content of the state’s soil is similar to that in the St. Louis region, allowing the soil to hold moisture longer than sandy soils.
2. Wood-to-Ground Contact Elimination
Remove any wood debris, mulch against your foundation, or firewood sitting directly on the ground around your property. Store a stack of firewood at least 20 feet away from the home and up on racks. That decorative wooden landscaping timber that’s in contact with your foundation? They are basically highways for termites to your home.
Timing Matters: Why November Works Best for Prevention
Dealing with termites in November instead of spring has a hidden, but significant, benefit. Fall months usually have lower demand for treatment companies, providing more flexible scheduling and often more thorough service. Lastly, addressing termite issues ahead of winter will allow time for products to become established before the swarming activity in the spring. Pointe Pest Control, along with other local companies, knows that treatments now can jumpstart home protection for St. Louis homeowners this fall. They are familiar with the termite pressures that plague homes in our area, such as the historic neighborhoods of Soulard and newer developments in West County.
