Pest control costs depend on your project and location. Check with a local pro for your specific job.
Termite treatments are designed to destroy nests and remove termites that may have infested a property, ideally before they can cause serious damage.
Expect to pay at least several hundred dollars for the average termite treatment in St. Louis, which includes fees for pest inspections.
Significant cost factors include the treatment options you choose, like bait traps or spraying, as well as how large the affected area is.
If the termites have already caused damage, especially to wood beams or other structural materials, you should arrange for repairs, too.
In St. Louis, expect to pay $416 for termite treatment, or somewhere between $162 and $691. Termite species are a threat to homes that aren’t protected in the St. Louis area, where they can create expensive damage if they run unchecked. That means if you start spotting lots of termites, it’s time to contact an exterminator near you and arrange for an inspection to plan next steps.
If your St. Louis property is having trouble with termites, it’s important to narrow down the cause fast and create an action plan to avoid more serious problems. That starts with a professional inspection to find out where the termites are and what treatments will be most effective. Here are the cost factors that matter the most.
The number of treatments you need will also affect your total termite treatment cost. Largely, the number of treatments required depends on the severity of the infestation. As stated above, a one-time termite treatment will run between $200 and $1,000.
Instead, you can set up annual, monthly, or quarterly treatments with a termite control company near you. You can expect to pay between $200 and $400 annually, $650 to $900 monthly, and $200 to $600 quarterly.
| Number of Treatments | Average Cost |
|---|---|
| One-time | $200–$1,000 |
| Annually | $200–$400 |
| Monthly | $650–$900 |
| Quarterly | $200–$600 |
Your total termite treatment cost will also depend on the infestation level. Getting rid of a small colony of termites will cost much less than tackling a mature colony, which could include thousands of termites. If you notice signs of a termite infestation, such as mud tunnels, holes in your wood, and bubbling or buckling floors or walls, your best bet is to call a professional pest control company immediately. Depending on the severity of your infestation, a pro can recommend the best types of termite treatment for your home.
| Level of Infestation | Cost Range |
|---|---|
| Small | $250–$1,200 |
| Medium | $400–$1,500 |
| Large | $1,200–$3,000 |
A professional exterminator can recommend the type of treatment most effective for squashing these determined little buggers. Some treatments are more effective on certain species, but the seriousness of your infestation will also play a role. Here are the different treatment types and associated costs:
| Treatment | Pros | Cons | Costs |
|---|---|---|---|
| Chemical termiticide | Effective when termites are caught early, affordable, can be used in many situations | Toxic and not for use inside the home, not long-term | $3–$16 per linear foot |
| Termite bait | Effective long-term, safe to use in many locations | Requires time to work and follow-up visits | $8–$12 per linear foot |
| Termite tenting/fumigation | Treats the entire house at once | Very expensive, toxic, requires leaving home for a time, struggles to reach termites outside of the house or in the foundation | Flat fees from $1,200 to $2,500 or $5–$20 per linear foot |
| Termite tenting with heat | Avoids the toxicity of old-fashioned fumigation, effective on all exposed termites | Expensive, time-consuming, struggles to deal with termites underground | Flat fees from $1,200 to $2,500 or $5–$20 per linear foot |
If your entire home needs to be tented and treated at once, it may cost $2,500 or more, or around $5 to $20 per linear foot. Larger homes cost more to treat, especially those with multiple floors, attics, and basements that need attention. Smaller applications can range from $200 to $1,000 for one-time treatments, depending on the location, the severity of the damage, and the number of termites in your home.
| Home Size in Square Feet | Average Cost of Fumigation |
|---|---|
| 1,000 | $3,000–$20,000 |
| 1,500 | $4,500–$30,000 |
| 2,000 | $6,000–$40,000 |
| 2,500 | $7,500–$50,000 |
| 3,000 | $9,000–$60,000 |
| 3,500 | $10,500–$70,000 |
| 4,000 | $12,000–$80,000 |
The location of the termite infestation on your St. Louis property can also affect pest control costs. The more isolated the infestation, the lower the costs to treat it. For example, termites confined to a shed, barn, or detached garage are more affordable to tackle than termites infesting a home foundation. The more ground there is to cover and the more wood there is to protect, the higher the costs will be.
You should bring in an expert to handle termite infestations to find out exactly how much damage termites have done and stop them before they spread. Instead of adding up the hours of their work, exterminators charge a flat fee combining the factors we discussed above in addition to a fee for the original inspection.
Termite infestations can be difficult to detect, so keep an eye out for changes in your wood features, such as floors bubbling or deck sagging. Don't hesitate to take pest control action to prevent the infestation from growing.
Exterminators will also want to arrange an annual or semi-annual service to make sure termites aren’t coming back and to re-apply barriers. If termites are a known problem in your St. Louis area, consider one of these maintenance plans, which cost $100 to $200 per year on average.
Your pest control pro should be able to take care of any treatment options as well as repeat visits if necessary. But it’s important to get a thorough examination of any damage the termites have caused and hire a professional repair contractor if necessary. Contacting a contractor is especially important if it looks like termites caused structural damage to beams, foundations, or flooring.
