Where to Use

Woodworker Ants:
  • Woodworker ants typically originate from an outside province and go into your home hoping to set up a satellite state in a zone containing water-harmed wood. Craftsman ants are anything but difficult to recognize in light of the fact that they are bigger than every other insect. Regularly you will discover them living in wood that has been in contact with water, for example, around downspouts and canals, close window sills and entryway openings, near spilling water funnels, or around decks. Craftsman ants are most dynamic amongst nightfall and sunrise — find their outside trails amid this time. Woodworker ants take after particular trails, for example, edges of scene timbers, along the ground near outside dividers, close downspouts or along the edge of an outside divider.
    Apply TERRO Outdoor Ant Killer to all territories where you presume ants are entering the home. Seal any noticeable outside splits where ants can be seen entering the home. On the off chance that you locate the principle settlement outside in the yard, treat the regions where ants are seen entering the fundamental province.

Center your treatment in key regions outside the house, where you speculate ants are entering the structure, for example, around downspouts and canals, close window sills and entryway openings. Splash ants specifically where conceivable. Seal up any unmistakable outside breaks where ants can be seen entering the home. Splash subterranean insect trails, slopes, insect hills and different zones of passage and pervasion.

Other Crawling Insects:

Questions Before Buying an Ant Killer

Why Are Ants Such a Pest?

Ants are normally harmless, but you may be suffering from fire ants that bite and hurt, or you may be suffering from carpenter ants which cause damage to your home’s wood. There are a lot of ant species, and one of the reasons that they’re such a pest is because they are multiplying rapidly.

You may have a 300 worker colony in the summer, and then in the winter, you may have over 2,000 worker ants per queen.

The largest colony has over 306 million worker ants, but you’re very unlikely to come across a colony of this size. But you may come across a colony with 500 – 200,000 ants. There are fire ant colonies with over 100,000 ants.

The size of these colonies makes them a pest for humans.

Ants are foraging for food, and even the smallest crumb you drop on the floor can be a feast for an ant. Since ants leave trails behind, other ants will smell the chemicals and follow the trail.

This is why you’ll see ants forming a long line to the ant traps that you place.

Everyone in an ant colony works together, so all of the ants naturally alert others to food and will follow the trail to where the food is located. For humans, it’s unsettling to see hundreds of ants crawling around the kitchen, through carpeting or all over the bathroom floor.

Fire ants can be very invasive, and since they actually bite, they’re one of the worst forms of ants you can have. These ants are even deadly to small animals, so you need to be very cautious if you have fire ants in your yard and a small cat or dog.

There are also different types of traps. Some traps will work on fire ants, but they won’t work on carpenter ants. You need to be very cautious of the traps that you choose to ensure that your trap is designed to kill the ants that you’re targeting.

You will find a lot of general ant traps and poisons that are designed to kill most ants. It’s recommended that you observe the ants when placing bait to determine if they’re avoiding the bait or not. Some species have evolved and will avoid common baits because they know that they’re deadly.

If this is the case, you may need to try another form of bait. I recommend viewing the active ingredients in your selected bait to ensure that they’re not the same as in the bait that the ants are ignoring.

Will Ant Traps Attract Ants?
Yes. Lots. Ant traps are great because they will destroy ant colonies, but they’re also bad because you’ll see long trails of ants going to the trap. Ants will alert others that they have found a food source, so at the very beginning, you’ll often see hundreds of ants swarm the trap.

A lot of people opt for clear traps because they can watch the ants gather the bait.

Some ants will not make it back to the colony, so they will die inside or close to the trap. You have to remember that the queen ant must die, so it takes a while for the worker to return to the hive and kill the entire colony.

Once the queen dies, new ants should not be born and the colony will quickly collapse. You need to give it a few days, and in severe cases, a few weeks before all of the ants are terminated.

When Should I Use Ant Sprays?
The best ant spray may not be a good idea for a kitchen. Why? You have little control of where the spray goes. You might directly spray a slew of ants, but the spray will go into the air and may contaminate your food.

One time that ant sprays really work best is when there is an immediate problem.

For example, I had an infestation of ants in my bathroom. I didn’t want ants crawling at my feet when I was going to the bathroom, so I decided to use an ant spray. The spray is highly toxic, so it will kill ants on contact.

I also recommend opening the window to be able to air out the bathroom.

You’ll find that sprays are great when used with ant traps or other forms of repellent. The goal of a spray is to immediately kill, but there are some sprays that also act as a repellent. These repellent sprays will keep ants away from the area for hours.

An entire colony of ants will not die with ant spray, so you’ll want to use the bait of some kind instead.

Sprays are also not ideal when used near animals, children or food.

When Should I Use Ant Gel?
I’m a big fan of any gel, and it’s one of the best ant killers for the kitchen. What’s really nice about gels is that they can reach into cracks and crevices with ease. You will find that these gels are very effective against sugar ants.

If you have holes or cracks, you can apply a gel to keep the ants from coming indoors.

Gels will have some form of bait, so they will allow the ants to carry the bait back to the colony and kill the queen. Gels are also long-lasting, and they can stay active for a month as long as they are not removed.

The gel will take time to dry, and when not dry, the gel will not be waterproof.

What does this mean?

The gel can easily be removed if water touches it or it rains. And a lot of people complain that once the gel does dry, it is no longer appealing to ants. I find gel to be most effective in areas where you see ants entering or exiting a room.

Tiny cracks in a floorboard or on the trim in a room are perfect areas to apply the gel.

Since most of these gels come with a syringe, you can apply the gel to the cracks and not worry about animals or kids coming in contact with the gel. There’s also no need to worry about the gel entering the air and getting on any of your food.

Just remember to wash your hands thoroughly after handling any form of ant bait, repellent or control.

When Should I Use Ant Granules?
Ant granules are great products, and they’re meant to be used outdoors although some forms can be used indoors. Some of the granules are safe for animals, but others are not, so make sure that you read the warnings on the package.

Offering long-term solutions, granules are ideal for large areas of land.

Some ants are “smart,” and what I mean is that granules may become less effective over time. You need to keep a close eye on the granules to see if ants are actually avoiding them.

And while the ideal solutions to kill ants outdoors, granules also require a lot of work on your part. Some need a spreader while other forms may need to be mowed over before they start working.

There are also water-in options that will require water before being effective.

If you do find a good granule ant killer, you’ll be able to control ants in your yard all season long. The ants will eat the granules, bring it back to the colony and cause a massive collapse in the process.

High-end options will allow you to keep your lawn and yard ant-free. Pest control specialists often use granules to control ants. You can also place some of these granules around or on top of the ant mound.
