Fipronil Plus-C Insecticide Concentrate — Kills Roaches, Ants, Fire Ants, Stink Bugs, Spiders & More — Non-Repellent Colony Killer — Makes 21 Gallons — 16 oz

THEY CARRY IT BACK TO THE NEST — ENTIRE COLONY DIES: Unlike repellent sprays that simply push pests to another room, Fipronil Plus-C is completely undetectable to insects. Roaches and ants walk through the treated area, unknowingly pick up fipronil on their bodies, and transfer it to nestmates — including the queen. The whole colony collapses within days, not just the individual bugs you can see.
SAME ACTIVE INGREDIENT AS PROFESSIONAL-GRADE TERMITICIDES — NOW FOR HOMEOWNERS: Formulated with 0.65% Fipronil — the same active ingredient used in commercial pest control — plus a patented Cellulose Entrapment Technology developed by a board-certified entomologist. The cellulose encapsulation protects the formula from UV breakdown and microbial degradation, keeping treated surfaces active for 30–90 days, even outdoors in direct sunlight.
ONE 16 OZ BOTTLE MAKES UP TO 21 GALLONS OF TREATMENT-READY SPRAY: Three dilution rates let you match treatment intensity to the infestation — 0.25 oz/gal for maintenance, 0.75 oz/gal for initial treatments, and 1.5 oz/gal for severe infestations. A single bottle covers your entire home's interior, perimeter, and yard multiple times over — at a fraction of the cost of a professional pest control visit.
KILLS 11+ PEST TYPES INDOORS AND OUTDOORS: German Cockroaches, Ants, Fire Ants, Spiders, Asian Lady Beetles, Brown Marmorated Stink Bugs, Boxelder Bugs, Crickets, Earwigs, House Flies, and Pillbugs. Labeled for use in homes, apartments, hospitals, schools, restaurants, hotels, and food-handling facilities. Apply to baseboards, wall voids, crack & crevice, perimeter foundations, ant mounds, and outdoor harborage areas.
NOT A CONTACT KILLER — THAT'S THE POINT: Fipronil's slow-acting formula (24–36 hours to kill) is what makes it so effective — pests survive long enough to carry it back to the colony before they die. Expect to see pest activity for the first few days after treatment; this means it's working. Residual protection lasts 30–90 days per application with reduced spray drift and even adhesion on both vertical and horizontal surfaces — so it stays where you put it.

Conquer Cockroaches: Your Ultimate Buying Guide to Roach Insecticides

Roaches are unwelcome guests. They scurry in the dark and can spread germs. Luckily, you have powerful tools to fight back. Roach insecticides can help you reclaim your home. This guide will help you choose the best product for your needs.

Key Features to Look For

When you shop for roach insecticide, keep these important features in mind.

Type of Application: Insecticides come in different forms. Sprays are good for quick action. Baits work over time. Powders can get into cracks and crevices. Gels are precise and target specific areas.
Active Ingredients: This is the part of the product that kills roaches. Look for ingredients like fipronil, indoxacarb, or hydramethylnon. These are proven to be effective.
Residual Effect: Some insecticides keep working for weeks or months. This is called a residual effect. It means fewer treatments are needed.
Targeted Action: Some products are designed to kill roaches on contact. Others are slow-acting and are carried back to the nest, killing more roaches.
Safety: Consider if the product is safe for pets and children. Many products have safety warnings. Always read them carefully.

Important Materials

The materials used in roach insecticides are crucial. They determine how the product works and how safe it is.

Active Ingredients: As mentioned, these are the chemicals that kill roaches. They are designed to disrupt the roach’s nervous system or other vital functions.
Inert Ingredients: These are the other parts of the product. They help the active ingredient work better. They can also make the product easier to use. Examples include water, solvents, or attractants.
Packaging: The packaging protects the product and makes it easy to apply. Sprays come in aerosol cans or pump bottles. Baits are often in small plastic stations. Gels are in syringes.

Factors That Improve or Reduce Quality

Certain things make a roach insecticide better or worse.

What Improves Quality:
- Proven Effectiveness: Products with good reviews and a history of success are usually high quality.
- Ease of Use: A product that is simple to apply saves you time and frustration.
- Long-Lasting Protection: Residual insecticides offer better value and convenience.
- Specific Roach Types: Some insecticides are better for certain kinds of roaches.
What Reduces Quality:
- Weak Active Ingredients: If the active ingredient is not strong enough, it won’t kill roaches effectively.
- Poor Application Design: A spray that dribbles or a bait station that is hard to open can be frustrating.
- Short Lifespan: Insecticides that stop working quickly require more frequent application.
- Unpleasant Odors: Some products have strong smells that can be bothersome.

User Experience and Use Cases

How people use roach insecticides matters.

Homeowners: Most people use these products in their kitchens, bathrooms, and basements. They target areas where roaches hide, like under sinks, behind appliances, and in cracks.
Apartment Dwellers: Roaches can spread easily between apartments. Targeted baits and gels are often preferred to avoid spreading chemicals widely.
Restaurants and Food Businesses: These places need strong, fast-acting solutions. Professional-grade products might be necessary. Strict adherence to safety guidelines is essential.
Preventative Use: Some people use insecticides to prevent roaches from entering their homes in the first place. They might apply barriers around entry points.

Frequently Asked Questions (FAQ)

Here are answers to common questions about roach insecticides.

Q: What is the best type of roach insecticide?

A: The best type depends on your situation. For fast results, sprays are good. For long-term control, baits and gels are effective. For hard-to-reach spots, powders work well.

Q: Are roach insecticides safe for pets?

A: Some are safer than others. Always check the product label for pet safety information. Keep pets away from treated areas until they are dry.

Q: How often should I use roach insecticide?

A: This varies by product. Read the instructions carefully. Some products last for weeks or months. Others need to be reapplied more often.

Q: Can I use roach insecticide if I have children?

A: Yes, but with caution. Choose products labeled as safe for homes with children. Keep children away from treated areas until the product is dry.

Q: What are the most common active ingredients?

A: Common active ingredients include fipronil, indoxacarb, hydramethylnon, and permethrin. These are effective at killing roaches.

Q: How do roach baits work?

A: Roaches eat the bait, which contains poison. They then go back to their nest and die. Other roaches eat the dead roach and also die.

Q: What is a residual insecticide?

A: A residual insecticide continues to kill roaches for a period after application. This provides ongoing protection.

Q: Can I spray insecticide directly on roaches?
