Spiders can be a nuisance in homes and businesses, and while many people try to get rid of them using DIY methods, professionals often use specific chemicals to effectively eliminate spider infestations. In this article, we will explore the different types of chemicals that professionals use to kill spiders, their active ingredients, and how they work.
Understanding Spider Infestations
Before we dive into the chemicals used to kill spiders, it’s essential to understand why spider infestations occur in the first place. Spiders are attracted to homes and businesses that provide them with food, shelter, and a suitable environment to live and breed. Some common reasons why spiders infest buildings include:
- Presence of insects: Spiders feed on insects, so if your home or business has an insect infestation, it’s likely to attract spiders.
- Moisture: Spiders need a humid environment to survive, so buildings with high moisture levels or water damage are more likely to attract spiders.
- Clutter: Spiders like to hide in cluttered areas, such as basements, attics, or storage rooms.
- Poor sanitation: Buildings with poor sanitation and hygiene are more likely to attract spiders.
Types of Chemicals Used to Kill Spiders
Professionals use a variety of chemicals to kill spiders, depending on the type of spider, the severity of the infestation, and the location of the infestation. Some common types of chemicals used to kill spiders include:
Insecticides
Insecticides are the most common type of chemical used to kill spiders. They work by targeting the spider’s nervous system, causing paralysis and eventually death. Some common active ingredients in insecticides used to kill spiders include:
- Pyrethroids: These are synthetic versions of natural insecticides found in chrysanthemum flowers. Pyrethroids are commonly used in sprays and aerosols to kill spiders.
- Neonicotinoids: These are a class of insecticides that work by blocking the spider’s nicotinic acetylcholine receptors, causing paralysis and death.
- Organophosphates: These are a class of insecticides that work by inhibiting the spider’s acetylcholinesterase enzyme, causing paralysis and death.
Residual Sprays
Residual sprays are a type of insecticide that leaves a residue on surfaces, providing long-term protection against spiders. These sprays are often used in areas where spiders are most active, such as basements, attics, and crawl spaces. Some common active ingredients in residual sprays used to kill spiders include:
- Permethrin: This is a synthetic version of a natural insecticide found in chrysanthemum flowers. Permethrin is commonly used in residual sprays to kill spiders.
- Cyfluthrin: This is a synthetic version of a natural insecticide found in flowers. Cyfluthrin is commonly used in residual sprays to kill spiders.
- Lambda-cyhalothrin: This is a synthetic version of a natural insecticide found in flowers. Lambda-cyhalothrin is commonly used in residual sprays to kill spiders.
Dusts
Dusts are a type of insecticide that is applied directly to surfaces, providing long-term protection against spiders. These dusts are often used in areas where spiders are most active, such as basements, attics, and crawl spaces. Some common active ingredients in dusts used to kill spiders include:
- Diatomaceous earth: This is a natural substance made from the fossilized remains of tiny aquatic organisms. Diatomaceous earth works by dehydrating the spider, causing death.
- Silica gel: This is a natural substance made from silicon dioxide. Silica gel works by dehydrating the spider, causing death.

What chemicals do professionals use to kill spiders?
Professionals typically use a variety of chemicals to kill spiders, depending on the type of spider and the severity of the infestation. Some common chemicals used include pyrethroids, neonicotinoids, and organophosphates. Pyrethroids, such as permethrin and deltamethrin, are commonly used to kill spiders and other insects. They work by disrupting the spider’s nervous system, causing paralysis and death. Neonicotinoids, such as imidacloprid, are also effective against spiders and work by interfering with their nervous system.
It’s worth noting that professionals may also use a combination of chemicals to achieve the best results. For example, they may use a pyrethroid to kill the spiders quickly, and then use a neonicotinoid to provide longer-term protection against re-infestation. Additionally, professionals may also use other methods, such as sealing entry points and removing webs, to help control spider populations.
Are the chemicals used to kill spiders safe for humans and pets?
The safety of the chemicals used to kill spiders depends on the specific chemical and the circumstances of use. Generally, the chemicals used by professionals are considered safe for humans and pets when used according to the label instructions and in a well-ventilated area. However, it’s still possible for exposure to occur, especially if the chemicals are not used properly. Pyrethroids, for example, can cause skin irritation and respiratory problems if inhaled.
To minimize the risk of exposure, professionals typically take precautions such as wearing protective clothing and respirators, and ensuring that the area is well-ventilated. They may also use specialized equipment, such as sprayers and foggers, to apply the chemicals in a controlled manner.
