Spiders can be very scary, especially if you have a phobia. There are also many times where you might encounter a spider, like the black widow or even a brown recluse. A bite from these spiders can even result in you ending up at the hospital.

Spiders can, however, be difficult to catch. There can be times when you might grab the thing next to you, just so you can get rid of the spider. Often, people might only have ant sprays in their houses. But, does ant spray kill spiders? To answer this question, we have done all the research for you. Today, we will tell you about how ant sprays work and whether or not they kill spiders or not!

How Do Ant Sprays Work?

The main objective of any ant spray is to get rid of them as soon as possible. To do so, some ant sprays contain chemicals that can help stop the physical processes inside the ants. You will also find some ant sprays that make use of bacteria, virus, or fungi, that can help kill the ants.

Most commonly, you will find ant sprays that directly affect the insect’s nervous system and its metabolism or growth.

Let’s dive deep to see how ant sprays work!

Ant sprays contain chemicals such as organophosphates, carbamates, chlorinated hydrocarbons, and pyrethroids. These chemicals are responsible for disrupting the transmission of nerve impulses in the insects that they are sprayed on. The chemicals inhibit the synapses, causing disruption in bodily functions. Ants will end up with paralysis or uncoordinated movement.

Ant sprays can also affect their respiratory system. Some ant sprays contain potassium salts that disrupt the ant’s breathing. The salt penetrates the body and starts attacking the respiratory cells. This causes the breathing tubes to stop functioning. Similar course of action will take place in a spider’s body, when sprayed with an ant spray.

Some ant sprays also contain insect growth regulators (IGR). When ants grow, they often shed their skin and grow a new one. The process of molting is disrupted by the IGR in the ant spray. The IGR comes with chemicals such as Methoprene that inhibits the growth hormone in an ant’s body. Luckily, the IGR does not affect humans since our bodies do not have the receptors for them. If you have pets, make sure that you use a pet-friendly ant killer. However, ant killers are ineffective on spiders. This may be one of the reasons why your ant spray is not effective on the spider, as much as you would have expected.

Ant sprays can also contain insect-attacking microbes that can help get rid of ants. Whenever ants ingest the ant spray, the microorganisms present in the ant spray, attack the cells inside the ant’s body. The microbe also multiplies in number to make sure that they kill effectively.

Can Ant Sprays Affect Spiders?

Does Ant Spray Kill Spiders? And What Else Can You Use?

Long answer short, ant sprays can help kill spiders. However, they can only kill a spider if the spray is sprayed directly onto the spider. However, you won’t be as lucky against a whole colony of spiders, if you use an ant spray or any other insecticide.

The reason behind this is the fact that an insecticide won’t work as effectively on spiders as it would on other insects.

There can be some ingredients in the ant spray which does not affect the spider. However, that does not mean that the spray is completely useless. In fact, ant sprays contain some active ingredients that can be harmful to the spiders if they come in physical contact with the spray particle.

When it comes to ants, they can easily come into contact with the spray particles. This is because of the way they move, their bodies remain close to the ground. However, when it comes to spiders, physical contact with the spray can be hard. This is because spiders come will longer leg as compared to ants. Their bodies are unable to touch the ground. This is why, simply spraying the ant spray, might not do the complete job.

Ants also pick up food from the ground that has a high possibility of being contaminated with ant spray. Ants ingest the ant spray in this way. On the other hand, spiders do not eat in this way, which is why there is less chance for them to ingest the ant spray.

To kill a spider with an ant spray, make sure that you directly spray it on the spider. This ensures that there is physical contact between the spider and the insecticide, decreasing the chances for the spider to escape.

For best results, you can use Terro Aerosol Spray, which also kills spiders as well as other insects. This spray can be directly sprayed even in corners and places that are hard to reach. You can even use the ants on the ceiling guide to help eliminate spiders from the ceiling.
