Common questions
How much does termite treatment cost?
A liquid barrier treatment - trenching around the foundation and drilling through concrete to create a continuous treated zone - commonly runs 1,000-3,200 dollars for a typical home perimeter. Inspections run 100-300 and are often credited against the job or offered free as a promotion. Bait systems are priced differently and usually carry an annual monitoring fee.
What questions separate a good company from a cheap one?
Four: what exactly is being treated and with what method; how many visits are included and what a return visit costs; what the agreement term, renewal price and cancellation cost are; and what the guarantee obliges them to do if the pest comes back. Companies that answer all four in writing are rarely the ones that cause problems later.
Is pest control safe around children and pets?
Product labels carry legally binding directions covering application, ventilation and re-entry, and a professional is required to follow them. Tell the company in advance about pregnancy, infants, pets, fish tanks or asthma, and ask which products will be used and for the labels. Where a lower-risk approach exists - baits and targeted application rather than broadcast spraying - it is reasonable to ask for it.
Do I have to leave the house during treatment?
For most routine interior treatments the rule is set by the product label, which is federal law - commonly re-entry once treated surfaces are dry. The widely circulated 'twelve hour' figure comes from agricultural worker protection standards and does not apply to homes. Fumigation is different and does require vacating. Ask the technician what will be applied and what the label requires.
How much does pest control cost?
In 2026 published ranges, a one-time general treatment runs 150-500 dollars and recurring quarterly service 100-175 per visit, with typical annual spending of 300-900. The first visit is often discounted or waived when you sign a recurring plan. These are market ranges from price aggregators, not quotes - your price depends on pest, property size and local rates.
