Types of Ant Killers
There are two different types of ant killers, baits and sprays. They each work a bit differently and have different goals.
This is why a lot of professional exterminators use a combination of the two for particularly bad infestations.
The goal of a spray treatment is to kill the ant as soon as it makes contact. These treatments are for a broader application and are generally effective on a wide range of insects, from ants to cockroaches to termites.
Another key feature of sprays is that they’re effective for a much longer period of time than bait. In fact, they can sometimes last up to 3 months. They’re also much cheaper to make than baits and can cost significantly less.
It’s a little bit easier to get spray into the right area because all you have to do it put it where the ants are known to go. For example, if they’re always scavenging around the garbage cans, that’s a good place to spray.
The downside is that sprays only treat the ants that are out and about, away from the mound. Even spraying near the mound doesn’t guarantee that you’ll wipe out the whole colony because, in order to do that, you have to get the queen.
Bait works much differently than killer sprays because it’s meant to be taken back to the nest to get the queen. It has delayed effectiveness to give the workers time to ingest it then carry some back with them.
One difference between bait and spray is that bait is only effective for a short amount of time. The longer it sits out in the sun and rain, the more it breaks down and the less effective it is. Baits are usually only effective on ants and each works on only a few ant species.
Bait is meant to lure the ants to it by acting like good-tasting food. One reason why bait can be a little difficult to use is that there may plenty of other, more enticing things for the ants to eat.
The one major benefit to ant baits is that they’re meant to be taken back to the queen and therefore designed to wipe out entire colonies. How effective they are at doing this depends on a few factors, as we’ll see later.
Which Is Best?
It’s hard to say which ant killer type is best because there are so many factors to consider, including the type of ant, environment, moisture, and how well you’re able to establish where feeding trails and mounds are.
How to Choose the Best Ant Killer?
There are several things to consider when choosing an ant killer.
The first thing you have to decide is whether you want to use a spray or a bait. If you have problems with multiple insects or if you aren’t able to locate specific trails and mounds, a spray might be the better option.
Another thing to remember is that sprays tend to last a little longer and aren’t as affected by rain and wet weather. If these things are a concern, liquid ant killers might be a better option for you.
If you decide to use bait, the best thing to do is try to determine the kind of ants you’re dealing with because this determines what kind works best. Some ant varieties prefer sweets while others prefer greasy food.
If you’re not sure what kind of ant you’re dealing with, you can always use trial and error by seeing what kind of food they’re more attracted to or start with a sweet bait and, if that doesn’t work, switch to one that’s grease based.
How Does Ant Bait Work?
While any sprays work by instantly poisoning and killing the ants, baits have a more long-term goal and work a bit differently.
Ants and other insects that live in large colonies have workers and scavengers who go out and search for food to bring back to the mound or nest. Baits take advantage of this to eliminate the whole colony.
How does it work?
The fatal ingredients in ant bait don’t kill them immediately. The workers eat some of the bait and take the rest back to the nest where the entire colony eats it. Eventually, this will kill all the ants, even the queen.
Killing the queen is important so that the colony doesn’t reappear. If you’ve even gotten rid of an ant mound only to have another one pop up a few feet away, it’s likely that you didn’t get the queen the first time and the ants have started building a new colony.
One of the things to remember about bait is that it takes time to work. The ants have to get it back to the nest and then all of the other ants have to consume it so don’t expect a whole colony to be destroyed overnight.
While some baits work quicker than others, you may have to wait a few weeks until you stop seeing ants altogether. Monitor different feeding trails and keep applying bait until the ant disappear.
How to Use Ant Bait?
The way that you apply ant bait helps to determine how effective it is. Here’s the best way to use ant bait to make sure you get results.
1. Spend some time watching the ants to locate their trails. These are the routes they travel when looking for food which means it’s the perfect place for bait. If you find more than one trail, bait everyone.
2. Check the trails every day and reapply the bait when it’s gone. If the bait is still there, it’s possible you’re using the wrong kind of bait and the ants don’t want to eat it. If this is the case, consider switching to another kind of bait.
3. Keep placing the bait along each trail until you stop seeing ants there.
4. Once the ants have started taking the bait, wait. It can take weeks for a colony to be wiped out.
Here are some helpful hints to make sure you have the best possible chance of the bait being successful.
- Use bait stations if needed to protect the bait from inclement weather.
- For best results, bait should be applied in temperatures about 70 and less than 90 degrees F. If the temperature is too hot, consider laying bait in the evening as that’s when the ant will be scavaging for food.
- Don’t place bait early in the morning if there is any dew on the grass.
- Don’t use any type of repellant near the bait.
- Remove any other sources of food if you can, including things like trash cans and pet food.
- Discard any unused bait after 6 months or so because it will no longer be fresh and the ants will not be attracted to it.
Is Ant Bait Safe for Pets?
In a word, no, but it does depend on the product so make sure you read all bottles carefully.
While the amount of poison in ant bait shouldn’t be fatal for a household pet, there are some dangers to be aware of.
A lot of these products come in large containers. While a few sprinkles might not affect your pet, getting into the container could be disastrous. Make sure you store any unused product securely and in an area where they can’t get to it.
If you’re concerned about your pet’s safety when using outdoor ant bait, the best thing to do is keep them away from the area until the infestation has been taken care of. This could mean keeping cats in the house or walking your dog instead of letting it run around the backyard.
If you’ve been avoiding your backyard because of a nasty ant infestation, the easiest way to take back what’s yours is to use the right ant killer for the job. By taking the time to discover the kind of ant you’re dealing with, you can pick the product that will be the most effective.
You also have to consider the environment. If you live somewhere where it’s particularly wet or hot, you may need to be more diligent about when and how you apply the ant killer to your yard.
One thing’s for sure, with the right ant killer and a little patience, your lawn will soon be ant-free. Get ready to spend some time outside without having to worry about the pests that might be out there, trying to get in.
