Pest control in Frisco

Mosquitoes into late fall. Denton County Public Health tracks West Nile virus and publishes mosquito maps at DentonCounty.gov/WNV. Its October 13, 2026 report counted the county's sixth human case of the year.

DSHS said in 2023 that mosquitoes stay active in much of the state into November and December, and it advises EPA-registered repellent and emptying standing water in toys, tires, buckets, clogged gutters and plant pots. On the Collin County side, ask the city or county what mosquito spraying, if any, covers your street.

Fire ants in spring and fall. Texas A&M AgriLife Extension prefers the Two-Step Method: broadcast a fire ant bait, then treat individual problem mounds. AgriLife says spring and fall are the best times to bait, because fire ants are less active in hot, dry summer months and mounds are harder to spot. If you hire this out, ask whether the plan follows that two-step approach.

Scorpions year-round around the house. The striped bark scorpion is the only one of Texas's 18 species found statewide. It turns up under rocks, boards and debris and around homes, so clearing yard debris helps whatever a company sprays. AgriLife says stings usually cause only moderate reactions, though a stung person should be watched for allergic reactions.

HomeGuide's national figures, from pages dated January 9, 2026 and November 21, 2025, give a benchmark for a Frisco quote:

• One-time exterminator visit: $100 to $600.
• Quarterly service: $80 to $150 per visit. Monthly treatments: $40 to $75 per visit.
• Mosquito control: $80 to $150 per visit, or $350 to $1,000 per season.
• Termite treatment: $225 to $2,500 for liquid or bait methods, $2,000 to $8,000 for whole-home tenting. An inspection costs $0 to $250.

Ask whether a quarterly plan includes callbacks between visits and whether mosquito service stops on a fixed date or runs as long as the season does. The Texas pest control guide covers pricing in more depth.

Texas requires anyone doing structural pest control for hire to be licensed under the Structural Pest Control Act, run by the TDA. Licenses come in categories, including general pest control, termite control, and lawn and ornamental, so a company licensed for general pests may not hold the termite category. TDA publishes lists of active commercial businesses, applicators and technicians, and a search by zip code or address.

A licensed business must carry at least $500,000 of bodily injury and property damage coverage with a $1,000,000 aggregate, and TDA requires that policy to cover property in the company's care, custody or control. Ask for the certificate of insurance.

Indoor treatments in Frisco homes and rentals

For an indoor treatment at an owner-occupied home, the technician must make TDA's consumer information sheet available to you. In a rental complex with five or more units, residents in or next to the treatment area must get at least 48 hours' notice by a posted sign or a notice at each unit. That notice can be waived only for an emergency treatment, and both sides must sign a statement saying so.

If you are buying in Frisco, the termite inspection report for the sale must be on TDA's prescribed Wood Destroying Insect Report form, from a licensed applicator or technician in the termite category. The inspection covers visible, accessible areas only, so inaccessible attics, hollow walls and spaces behind built-ins can hide activity it doesn't catch. A corrective treatment can be recommended only if there is visible evidence of active infestation, or of a past one with no sign of prior treatment.

If you are moving into a new Frisco home, book a house cleaning service in Frisco before the first treatment to clear clutter where pests hide. For more companies nearby, see pest control in McKinney, and the Frisco city page for local rules.
