Services Offered by Termite Inspection Companies

Knowing what services termite inspection companies offer can assist you in making an informed decision that fits your immediate and future needs. Many companies offer annual termite inspections with preventive treatments for consistent coverage. Depending on your circumstances, this may be more helpful than treating termites only once.

Exterior Inspection

Technicians inspecting for termites will be on the lookout for visible signs of infestation around your home's exterior. They'll focus on structures that meet the earth, outdoor wooden elements, and moisture-prone areas that might lure termites, such as the following:
  • Cracks in expansion joints
  • Deadwood
  • Firewood stacks
  • Pooling water around the foundation
  • Standing water on the roof
  • Wood mulch close to the foundation
  • Wooden deck supports
  • Wooden fences
Signs of termite activity include droppings, damaged wood, and mud tubes. If the inspector suspects activity in an inaccessible area, they may bore small holes or use special tools to look for termites.

Interior Inspection

When evaluating for termites, specialists often pair the exterior inspection with a meticulous interior inspection. This inspection concentrates on damp spots, possible entry points, and anywhere with wood or cellulose materials. They may examine the following:
  • Attics
  • Basements
  • Crawl spaces
  • Doorframes
  • Exposed beams or studs
  • Exterior walls
  • Hardwood floors
  • Under-sink cabinets
  • Windowsills
  • Wooden furniture
Your inspector will look for signs of termites, such as detatched wings, mud tubes, and harmed wood, which typically sounds hollow when knocked on. They might use a probing tool and moisture meter to look for termite damage and termite-friendly environments.

Treatment Recommendations

If an inspector identifies termites in your home, they'll usually suggest an effective treatment plan to eliminate the termites efficiently. Nontoxic options exist, too, including physical barriers, heat, and biological pest control agents such as beneficial nematodes. The Environmental Protection Agency (EPA) regulates common chemical treatments including liquid termiticides and baits. Liquid termiticides soak into the ground around your house to create a protective barrier. Baits contain cellulose laced with slow-acting insecticide. If these treatments aren't enough, you can schedule fumigation. Fumigation means vacating your home, tenting it, and introducing a gas that’s lethal to termites. To address your current termite infestation, the pest professional might propose a multipronged strategy.

Future Vulnerabilities

Complete termite inspections evaluate potential entry points as well as current issues. Inspectors search for wood-to-soil contact, leaks, and other things that could attract termites. The inspection company may advise landscaping modifications or structural changes to minimize possible entry points and increase drainage. Addressing these issues reduces the risk of future pest problems.

Continuous Monitoring

Certain termite treatments require regular inspection, replacement, or reapplication to keep working properly. For this reason, many reputable exterminators offer continuing service agreements that include annual or quarterly inspections. With this monitoring, technicians look for new or worsening termite activity. This also involves changing out baits and reapplying liquid treatments as needed. This recurring service lowers the chance of major damage and commonly comes with a warranty.

Termite Warranties

Termite inspection providers often offer a reservice warranty with their services. The warranty covers any extra work required to tackle the termite infestation if they return within a certain time frame after service. Some pest control companies even include repair warranties. These cover costs to repair new termite damage following treatment.

Factors To Consider When Choosing a Termite Inspector

Be sure to consider the following key factors when selecting a termite inspector.
  • Cost: Get price estimates from a minimum of three companies. Some may insist on completing an evaluation first before giving a quote.
  • Experience: How long a company has been in business often reflects its dependability and skill. Companies with more industry experience can typically handle termite invasions more effectively.
  • Guarantees: Choose providers that offer guarantees or warranties covering reservice or repairs. Make sure to get the agreements in writing for your records.
  • Licensing and insurance: Pesticide applicators in Missouri must be licensed by the Missouri Department of Agriculture. To obtain a license, an individual must complete a training program and submit proof of financial responsibility. You should also make sure your provider is properly insured. Any technician who applies restricted-use pesticides must be registered as an applicator by the EPA.
  • Reputation and reviews: Check the Better Business Bureau (BBB) website, read online reviews, and ask people you trust to gauge customer satisfaction with companies you're considering. Positive customer feedback suggests you'll likely be satisfied with the service.

How Much Does a Termite Inspection Cost?

The fee for termite inspection in O'Fallon is typically between $39 and $217. The exact rate depends on the company performing the inspection and your specific location. Many pest control providers offer no-cost termite inspections. This gives them a chance to evaluate your specific situation, propose solutions, and provide a customized estimate. You can then opt for either a one-time treatment or ongoing services. Some inspectors include termite inspections with other home inspection services meant for people purchasing or selling a home. In this case, expect to pay an inspection fee.

Frequently Asked Questions About Termite Control in O'Fallon

What are some signs of a termite infestation?

Common signs of a termite infestation include discarded wings, flying swarms, hollow-sounding wood, visible wood damage, frass (termite droppings), and mud tubes.

How often should my home be inspected for termites?

You should arrange inspections annually for termites. Yearly assessments are very important if your property is surrounded by trees or you've had termites before.

What is the best way to prevent termites?

You can best prevent termites by fixing any moisture issues right away, keeping wood off the ground, and keeping termite food sources far from your home. Use rubber mulch or rocks around your foundation instead of wood mulch, and cut back tree limbs and bushes from your house. Repair any plumbing leaks as soon as possible, and clean your gutters regularly for proper drainage.

What attracts termites?

Damp areas and unfinished lumber attract termites seeking food. Cardboard and paper also are made of cellulose that termites eat.

What is the difference between ants and termites?

Termites chew through and consume wood, as opposed to most ants, aside from the carpenter ant. Termites have straight antennae and uniform waists. Ants have segmented antennae and narrow waists. Also, termites stay hidden more than ants, which you often see actively looking for food.
