Ease of Use
The bottle makes it easy to use even in small spaces like porches, effectively clearing out bugs and mosquitoes.

The Ortho BugClear Insect Killer for Lawns & Landscapes Concentrate is a versatile insecticide that targets 235 types of bugs, including spiders, ants, ticks, mosquitoes, and fleas. This product stands out for its quick action, as it begins to kill insects within minutes and offers long-lasting control. This makes it highly effective for those who need immediate and durable pest management for their outdoor areas, including lawns, home perimeters, trees, and shrubs.

The concentrate form of the product requires mixing and must be applied with a separate sprayer like the Ortho Dial N' Spray or a tank sprayer, making it slightly less convenient for those looking for a ready-to-use solution. However, its flexibility in application methods can be seen as a benefit for those who already own spraying equipment.

Safety and environmental impact are important considerations, and while the product is effective, it does not specify being organic or eco-friendly, which may be a drawback for environmentally-conscious users. Additionally, it’s unscented and relatively lightweight, making it easy to handle during application. The product is best suited for those who need comprehensive, long-term bug control in medium to large outdoor areas and are comfortable with the mixing and application process.

Ease of Use

Residual Effect
Lasts a long time without needing frequent reapplication.
Ease of Use
Very easy to use: just spray where you see bugs or don’t want them, and you'll find dead bugs later.

The Ortho Home Defense Insect Killer for Indoor & Perimeter Refill2 is a versatile choice for managing not just spiders but also a range of other insects like ants, roaches, and fleas. This makes it a handy all-in-one solution for households dealing with multiple types of pests. One of its major strengths is its longevity, providing up to 12 months of protection indoors on non-porous surfaces, which means less frequent reapplication is needed.

This product is easy to use, particularly if you have the Comfort Wand from the original container, allowing for precise application in both indoor and outdoor settings like kitchens, bathrooms, and around the house perimeter. It is unscented, which is a plus for those sensitive to strong chemical smells. However, the product's safety profile is crucial to consider, especially around pets and children. While it is effective, it's important to follow the usage instructions carefully to avoid any potential harm.

The environmental impact is another aspect to note; chemical insecticides can have broader ecological effects, so this product might not be the best choice for those seeking an eco-friendly option. The 1-gallon size can be cumbersome to handle, and although it covers a good area, those with extensive pest problems might find it insufficient for larger properties. This insect killer is highly effective and user-friendly for those needing comprehensive pest control, but safety and environmental concerns should be weighed before use.

Rating
9.5
Type of Spider Killer
Coverage Area
Residual Effect

Most important from
8767 reviews

Type of Spider Killer
It's not just a killer but also a repellent. Spiders seem to avoid treated areas entirely after application.
Coverage Area
This product is incredibly effective, even in severe infestations. One user mentioned it cleared a spider-infested old farmhouse, leaving no spiders or webs within 24 hours of application.
Residual Effect
The long-lasting residual effect is impressive, with no live spiders seen for over a month after spraying, even during peak spider season.
Ease of Use
The sprayer is user-friendly and allows for easy application in hard-to-reach places. Simply screw on the sprayer, and you’re good to go.
Safety
Wearing protective gear like gloves, work glasses, and a face mask is recommended, especially when spraying overhead to avoid fine mist exposure.

Miss Muffet's Revenge by Wet & Forget is a spider killer designed for both indoor and outdoor use. It features Bifenthrin as the active ingredient, which is effective against most spiders except Black Widow and Brown Recluse. One of its strongest points is its long-lasting residual effect, providing protection for up to 12 months with a single application. The attached sprayer is convenient, allowing you to spray up to 10 feet, which is great for those hard-to-reach areas.

Users have found it easy to apply, with the recommendation to use it in calm weather and allow it to dry completely for the best results. However, safety precautions should be taken to avoid entering treated areas before the spray is dry. The product has an unlimited shelf life and is ready to use straight out of the package, which adds to its convenience. On the downside, it is not suitable for eliminating Black Widow and Brown Recluse spiders, which could be a significant limitation for some users. Additionally, while it is effective, Bifenthrin is a chemical insecticide, which may raise environmental concerns for those looking for eco-friendly options.

If you need a reliable solution for most spider issues and ease of use is a priority, this product is a strong candidate.

Buying Guide for the Best Spider Killers

Choosing the right spider killer can be crucial for effectively managing and eliminating spider infestations in your home or workplace. The best product for you will depend on several factors, including the severity of the infestation, the type of spiders you're dealing with, and your preferences regarding safety and environmental impact. Understanding the key specifications of spider killers will help you make an informed decision that best suits your needs.
Type of Spider KillerSpider killers come in various forms, including sprays, traps, powders, and natural remedies. Sprays are quick and easy to use, providing immediate results, but they may contain chemicals that some people prefer to avoid. Traps are non-toxic and can be effective for monitoring and reducing spider populations over time. Powders can be applied to hard-to-reach areas and provide long-lasting protection. Natural remedies, such as essential oils, are safe for use around children and pets but may require more frequent application. Choose the type that aligns with your needs and preferences.
Active IngredientsThe active ingredients in spider killers determine their effectiveness and safety. Common chemical ingredients include pyrethroids and pyrethrins, which are effective but can be harmful to humans and pets if not used properly. Natural ingredients like peppermint oil, vinegar, and diatomaceous earth are safer alternatives but may require more frequent application. Consider the safety of the active ingredients, especially if you have children or pets, and choose a product that balances effectiveness with safety.
Coverage AreaThe coverage area of a spider killer indicates how much space the product can effectively treat. Sprays and powders often specify the square footage they can cover, while traps may indicate the number of traps needed per room. For large infestations or bigger spaces, you may need a product with a larger coverage area or multiple units. Assess the size of the area you need to treat and choose a product that can cover it adequately.
Residual EffectThe residual effect refers to how long a spider killer remains effective after application. Products with a longer residual effect provide ongoing protection and reduce the need for frequent reapplication. Chemical sprays and powders often have longer residual effects, while natural remedies may need to be reapplied more often. If you prefer a low-maintenance solution, look for a product with a longer residual effect.
Ease of UseEase of use is an important consideration, especially if you are not experienced with pest control. Sprays are generally easy to apply and provide immediate results, while traps and powders may require more effort to set up and maintain. Natural remedies can be simple to use but may need more frequent application. Consider your comfort level with using the product and choose one that you find easy to handle and apply.
SafetySafety is a critical factor, especially if you have children, pets, or sensitive individuals in your household. Chemical spider killers can be effective but may pose health risks if not used properly. Natural and non-toxic options are safer but may require more frequent application. Always read the safety instructions and warnings on the product label, and choose a product that aligns with your safety requirements.
Environmental ImpactThe environmental impact of a spider killer is an important consideration for eco-conscious consumers. Chemical products can have negative effects on the environment, including harming beneficial insects and contaminating water sources. Natural and eco-friendly products are less harmful to the environment but may require more frequent application. If environmental impact is a concern for you, look for products labeled as eco-friendly or biodegradable.
