Ant Killer Buying Guide

To help you with ant control in your home, we put together this guide to help you narrow down your options when choosing the ant killer that’s best for you.

Type of Ant Killer

Ant killers can be divided into two categories—bait and kill-on-contact.

• Baits: These products slowly poison ants. By the time they take their full effect, the ant has already returned to its colony and spread the poison to other ants.
• Kill-on-contact: This type of ant killer eliminates ants right away. While kill-on-contact works quickly, it can’t tackle widespread infestations.

Depending on the size and severity of your infestation, you’ll want to choose your ant killer wisely. Larger infestations will likely call for bait, while just a few ants can often be treated by kill-on-contact methods.

Type of Insect

Most ant killers target several household ant species as well as other common pests. It’s not uncommon for a single product to kill:

• Carpenter ants
• Cockroaches
• Fire ants
• Flies
• Fleas
• Gnats
• Mosquitoes
• Pavement ants
• Spiders
• Ticks
• Wasps
• Other crawling and flying insects

Toxicity

Many ant killers can’t be used around pets or children because of their poisonous formula. This is especially true for baits because they’re placed on the ground where they can be easily accessed.

If you have pets or children, put your ant traps in hard-to-reach places, or use a non-toxic spray.

Application

The form an ant killer comes in affects how it’s applied. Popular forms include various forms of bait and topical pesticides. The most common types are:

• Dust-based insecticide
• Ant gel bait
• Granular bait
• Liquid bait
• Spray-based insecticide

Types of Ants

To understand how to make your home ant-free, you must first understand what types of indoor ants you’re dealing with. The four species of ants you will likely see around your home are:

• House Ants: These ants are typically active in the summer and drawn by sugary foods.
• Carpenter Ants: Carpenter ants are active near wood, making them dangerous to your home’s structure. They excavate wood in order to build their nests, which, over time, could damage the structure of your home.
• Fire Ants: Bright red fire ants are the most threatening type of ant. If they feel that they’re in danger, they will sting you, leaving you with a spot that burns, swells, and itches.
• Pavement Ants: Pavement ants are most active near concrete. They will eat almost anything and can contaminate foods.

If you can identify the type of ant that’s causing your infestation, make sure that the ant killer you choose targets this species.

The Best Areas to Put Ant Traps

Once you’ve found the best trap to eliminate ant activity in your home, the next question you may be asking is where you should place it in your home.

The smartest areas to keep traps are:

• Basements
• Behind appliances
• Closets
• Corners of rooms
• Doorways
• Home entry points
• Near food and water sources
• Near trash cans
• Underneath cabinets and furniture
• Windowsills

Frequently Asked Questions About Ant Killers

How do ants get in my house?

How did your infestation start? All homes have holes, cracks, and gaps that ants are adept at finding and climbing through if they have the motivation. You can try to seal these gaps, though this is likely a losing battle. Instead, focus on taking measures to prevent your home from being attractive to ants. The following tips will help you do this.

• Clean counters and floors to eliminate particles that could be a food source.
• Empty your trash regularly.
• Keep food sealed in your pantry, cabinet, or fridge.
• Ensure gutters move rainwater away from your home.

How do you use an ant killer?

It depends on what type you have. For baits, set them in the corner of a room where you have seen ants. For spray bottles, simply spray the killer directly onto an infested area or onto an insect itself. Be sure to read your killer’s use instructions, as the manufacturer will provide you with more details that pertain to your specific product.

What’s the best way to get rid of ants in my kitchen?

To get rid of ants in the kitchen and keep them from coming back, you need to target the entire colony. The best way to do this is with bait, as this gets carried back to the rest of the ants.

When should I contact an exterminator?

You should be able to eliminate even larger ant infestations with frequent use of the right ant killer. However, if your ant problem isn’t going away, it may be best to let the professionals handle it.
