You're paying a pest control company $80–$120 every month to spray your yard with a chemical you can buy on Amazon for $54 a gallon. That's not an exaggeration — the active ingredient in most professional mosquito treatments is bifenthrin, and you can get the exact same concentration in a bottle, mix it with water, and treat your entire property in 30 minutes. We're going to show you exactly how, and what you need to do it right.
The Math That Should Make You Angry
Professional pest control: ~$100/month × 7 months (mosquito season) = $700/year.
DIY with Talak: ~$54 for a gallon of concentrate (makes 128 gallons of spray) + $30 sprayer = $84 for the entire season.
That's $616 saved per year using the same active ingredient the pros use.
What the Pros Actually Spray
Most pest control companies use bifenthrin — a synthetic pyrethroid that kills mosquitoes, ticks, fleas, ants, spiders, and 70+ other pests on contact and provides residual protection for up to 3 months. The industry standard has been Talstar Professional for years. But Talstar's patent expired, and now generic bifenthrin concentrates deliver the exact same 7.9% formulation at significantly lower prices.

How to Apply (30-Minute Process)
Step 1: Mix. Add 1 fl oz of Talak per gallon of water in your pump sprayer. For extra protection, add NyGuard IGR per label directions to the same tank.
Step 2: Spray your perimeter. Walk the foundation of your house, spraying 3 feet up the wall and 3 feet out onto the ground. Hit every door frame, window frame, and where pipes enter the structure.
Step 3: Treat the yard. Focus on shaded areas, under decks, around bushes, tall grass, tree lines, and anywhere mosquitoes rest during the day. They don't fly in direct sunlight — hit the shade.
Step 4: Let it dry. Keep pets and kids off treated areas for 30 minutes until dry. Once dry, it's safe for people and pets but still lethal to insects for up to 3 months.
Reapply every 30–90 days depending on rainfall. Heavy rain will reduce residual effectiveness. Most people spray 3–4 times per season (April through October).
State Restrictions
Bifenthrin products including Talak and Bifen I/T are not available for sale in Connecticut, New York, or Vermont due to state pesticide regulations. If you're in one of these states, consider Thermacell for portable protection or contact a licensed applicator.
