Does Hairspray Kill Spiders?

If you apply hairspray to a spider with the intention of killing it, the chemicals in the spray will react with the spider’s body, leading to its death within a few minutes.

The effectiveness of the chemicals is quicker on smaller spiders, while larger ones may take longer to succumb.

Chemicals present in hairspray can be detrimental or harmful to spiders. Opting for a natural spider repellent is a more effective way to kill them without resorting to using hairspray everywhere.

Furthermore, it is worth noting that using hairspray may leave a sticky residue on the floor where it was applied to cover the spider.

How Does Hairspray Kill or Affect Spiders?

Hairspray Immobilize Spiders:

The effectiveness of hairspray in immobilizing spiders is primarily attributed to its sticky residue.

When hairspray is sprayed on a spider, the mist and propellant rapidly evaporate, creating a sticky layer that adheres to the spider’s legs, hairs, and body.

This sticky coating acts like a glue, limiting the spider’s ability to move freely. It restrains spiders, limiting their ability to crawl, climb, or jump.

The result is that the spider becomes trapped and finds it difficult to navigate due to the adhesive nature of the hairspray residue.

Hairspray Suffocates Spiders:

The respiratory interference caused by certain hairsprays, particularly those with alcohol or specific polymers, can impact a spider’s breathing.

The chemicals present in the hairspray have the potential to clog or irritate the small book lungs found on the spider’s abdomen.

As a result, the spider faces difficulty in taking in oxygen, leading to symptoms like lethargy, disorientation, and, ultimately, suffocation.

This respiratory disruption contributes to the overall effectiveness of hairspray in immobilizing and incapacitating spiders.

Hairspray-Induced Stress and Harm in Spiders

Using hairspray on spiders can have detrimental effects on their well-being.

The chemicals in hairspray, known for their potential to irritate, can distress the delicate skin and tissues of the spider. Furthermore, if the spider ingests hairspray during self-grooming, it may suffer internal irritation and damage to its organs.

While the immediate impact may not be fatal, the combined effects of immobilization, oxygen deprivation, and stress can gradually lead to the spider’s death.

Additionally, a partially immobilized spider becomes more susceptible to predation by other animals, as its ability to defend itself or escape is compromised.

How to Use Hairspray to Kill a Spider?

If you want to proceed with your hairspray to kill a spider, follow these steps:

Locate the Spider:

Spiders play a vital role in ecosystem balance by controlling insect populations. Typically, they prefer to stay out of sight and are often more afraid of humans than we are of them.

If a spider is not posing an immediate threat, it is advisable to coexist peacefully with it or carefully put it in a jar and shift it somewhere outside your place.

However, if you are determined to use hairspray to remove the spider, choose one with a potent adhesive formula for more effective immobilization. Identify the spider’s location before applying the hairspray.

Maintain Distance:

Stand at a safe distance from the spider to prevent direct contact.

Direct Application:

Aim the nozzle of the hairspray directly at the spider, covering it thoroughly. Allow some time for the hairspray to take effect without disturbing the spider.


Be prepared to clean any sticky residue left on surfaces.

Precautions to use Hairspray to Kill Spiders:

Ensure good ventilation in the area. Avoid open flames, heat sources, or electrical appliances to prevent the risk of fires.

How Much Hairspray Do You Need to Use to Kill Spiders?

Spraying a spider directly with hairspray for 3-5 seconds is typically sufficient to eliminate it. The hairspray coats the spider, obstructing its breathing and rendering it immobile.

Afterward, you can gently remove the spider using a paper towel or a dustpan and dispose of it.

Larger spiders may require more hairspray to ensure effectiveness, especially considering their tendency to flee upon encountering humans, making it challenging to apply enough spray.

Hairspray proves most effective against smaller spiders, where a brief application is generally adequate for successful elimination.

Does Hairspray Kill Spider Eggs?

If you apply hairspray on spider eggs, coating spider eggs thoroughly with hairspray creates a barrier that blocks the emergence of baby spiders and can be effective in preventing them from hatching.

However, larger egg sacs may still rupture, allowing the baby spiders to emerge, and even smaller spiders can sometimes break through the hairspray coating.

To prevent the hatching of baby spiders in your home, take measures to ensure that it does not occur.

It’s advisable to remove the egg sac carefully; using a broom or mop for egg sacs in elevated locations can be a practical and effective option.

How Fast Does Hairspray Kill Spiders?

Hairspray’s speed in killing spiders varies based on factors like spray type, spider size, and the amount used.

Generally, it is not an instant method, taking several minutes or longer for the chemicals to affect the spider. Larger or faster spiders may be more resilient.

However, the application of the hairspray will result in the immobilization of the spider, and you can easily remove the spider from your home.

What Natural or Household Spray Kills Spiders?

Numerous household sprays can effectively manage spiders, offering various options:

Insecticides: Seek out insecticide sprays specifically designed to target spiders, often containing chemicals like pyrethroids effective against various insects.

Peppermint Oil Spray: Create a natural deterrent by mixing water with peppermint essential oil and applying the solution in spider-prone areas, as spiders dislike the scent of peppermint.

Citrus-Based Sprays: Exploit spiders’ aversion to citrus scents by using a citrus-based spray or a water and citrus essential oil solution to repel them.

Vinegar Solution: Act as a natural spider repellent by spraying a mixture of white vinegar and water in areas where spiders are likely to be present.

It is crucial to acknowledge that while these sprays can assist in deterring or eliminating spiders, they may not offer complete effectiveness.

Adhering to safety guidelines is essential, and addressing the root cause of spider presence, such as sealing entry points and maintaining cleanliness, is advisable.

For persistent spider issues, consulting professional pest control services may be a prudent course of action.

Does Hairspray Kill Daddy Long Legs?

While hairspray may affect daddy’s long legs (harvestmen) to some extent, it is not a highly efficient means of controlling or eliminating them.

Daddy’s long legs, as arachnids, possess anatomy and behavior that make them less susceptible to certain substances like hairspray.

Daddy’s long legs stand apart from true spiders due to their inability to produce silk or construct webs, setting them distinctly apart from the silk-spinning behavior exhibited by true spiders.

Typically found in damp areas, they are generally harmless, lacking venom glands. Suppose you are concerned about Daddy’s long legs.

In that case, it is advisable to explore alternative methods for their management, such as physically removing them, creating less conducive conditions, or seeking professional pest control advice if necessary.

How Does Fly or Bug Spray Kill Spiders?

Fly sprays, containing nerve-disrupting ingredients like pyrethroids or pyrethrins, quickly immobilize and kill spiders.

When applied directly, these substances are absorbed through the spider’s exoskeleton, disrupting its nervous system.

These insecticides, designed for fast action, are effective in quickly eliminating pests, but success depends on factors like the product used and application method.

Adhere to product instructions and safety guidelines for responsible pest control.
