Dealing with spiders is like dealing with a jester. Exceptionally smart and eccentric, spiders are not very easy to kill or capture.
So, how do you get rid of them?
In this post, we’ll go over some of the best spider killers in the market. These devices will not only allow you to instantly kill spiders but also do it without much effort on your part.
Let’s dive in!
1. Black Flag Spider & Scorpion Killer – Best Aerosol Spray
Pros
Can spray accurately from a five-foot distance
Non-staining formula
Can cover up to 2,000 cubic feet of area
Easy to handle
Affordable
Can be used indoors and outdoors
The product can last up to six months
Cons
The formulation is toxic to aquatic creatures
Highly combustible
Produces a strong chemical odor
The nozzle is not adjustable
Not safe to be used around plants
Key Details
- Type of Killer: Aerosol Spray
- Active Ingredients: Prallethrin 0.025% and Lambda-Cyhalothrin 0.030%
- How Fast Does It Work: On Contact
- How Long Does It Last: 12 weeks
How Does It Work?
The Black Flag Spider & Scorpion Killer Aerosol contains Prallethrin and Lambda Cyhalothrin, which disrupts the bug’s nervous system upon contact.
To put this product into action, you can apply it directly to any spiders you see crawling around your home.
You can also use it as a barrier defense by applying it where you suspect spiders frequent or have crawled to recently.
For example, you can spray the window seals and door seals inside your home. Any spiders that come in contact with the sprayed areas will die. This is because Black Flag has a residual effect that lasts up to 6 weeks.
What I Like
Potent
This spray is potent because it is designed to kill large and tough spiders such as scorpions, black widows, brown recluse, and wolf spiders.
Prevents growth of insects
Not only does it kill adult insects, but it also kills eggs to prevent any future pest invasion.
This is a great way of stopping the spread and growth of an infestation.
Accurate Spray Tip
This aerosol can has an accurate and powerful spray tip. This makes it easy to spray spiders that are trying to escape.
If you are spraying as a barrier, you will be able to reach tight spaces and hard-to-reach areas with ease due to this spray tip.
What I Dislike
Confusing product design
The spray’s trigger mechanism is difficult to figure out. Additionally, the bottle’s sprayer doesn’t produce fog or mist when dispersing its contents, but it comes out as a powerful stream and in massive amounts.
Toxic
This product is toxic to both animals and humans. Be cautious when spraying this around your home to ensure no animals or humans will come in direct contact with the spray.
Strong odor
One major downside of this spray is that it leaves an odor. When you are spraying indoors, be sure to ventilate the area afterward.
The smell is pungent and can be disturbing to some.
2. Rescue! Spider Traps – Best spider Traps
Pros
Doesn’t leave any mess
Includes glue dot patterns to capture multiple spiders at once
Blends in with the environment
Can be placed in narrow spaces
Sturdy product built
Non-toxic
Great adhesive
Cons
Can only be used indoors
Should not be placed near children or pets
Expensive compared to other insect glue traps
Not eco-friendly due to plastic packaging
Key Details
- Type of Killer: Trap
- Active Ingredient: Glue
- How Fast Does It Work: On contact
- How Long Does It Last: After full dispose and apply the new trap.
How Does It Work?
The Rescue! Spider Trap contains hundreds of glue dots on its interior. The glue dots cover every side of the trap.
The trap has four entry points that the spiders can enter through. Unlike other glue traps, Rescue uses an adhesive dot technology rather than a flat adhesive.
This allows for the spiders to enter the traps deeper before they caught on the adhesive. The dot adhesive design prevents spiders from stacking up at the entrances which encourages more spiders to enter.
What I Like
Innovative but simple design
The product may look simple, but it is very innovative. It has four entry points with three individual traps resulting in more spiders getting caught.
Its extensive scattered glue dots keeps spiders traps while still allowing them to get deeper into the trap. This will prevent spiders from piling up at the entrance.
Non-toxic trap
It doesn’t contain any toxic chemicals, allowing you to place it anywhere inside the house freely.
Easy to use and durable
The product is sturdy and does not require any assembly. If you accidentally hit it, the trap won’t break, and you can quickly return it to its place.
What I Dislike
Ecologically impractical
The product is excellent, however, its whole unit is made up of plastic, and the traps can only be used once. If there are ways to throw out the glue traps instead of throwing away the whole thing, it would have been better.
No Lure
The issue with this trap is that it does not use a lure.
This means that you may have a hard time catching spiders but not other insects.
In some cases, the trap might fill up before you catch any spiders.
3. Nuvan Pro Strips – Best Spider Fumigation
Pros
Pest control effects can remain up to four months
Works on different types of pest
Odorless
Targets the central nervous system of pests
Cons
The slow-acting effect that can take up to a week
Can bring about harm when inhaled by pets or humans
May cause mild to moderate eye irritation
Expensive
Key Details
Type of Killer: Fumigant
Active Ingredient: DDVP 18.6%
How Fast Does It Work: takes up to 48 to 72 hours to contain bed bug nymphs and adults
How Does It Work?
The Nuvan Pro Strip features a “controlled release technology” that diffuses an odorless vapor that reaches even the narrowest crevices, ultimately killing all types of pests it comes in contact with.
One notable active ingredient is acetylcholinesterase, which targets the pest’s nervous system, causing paralysis and eventual death. Its effectiveness stays for as long as four months.
When using Nuvan Pro Strips for spiders there are some important takes aways.
You should not use Nuvan Pro strips in small confined spaces or where people frequent often.
For indoors use Nuvan Pro strips in areas that are not frequented often such as attics and crawlspaces.
If you want to use Nuvan indoors you will need to evacuate the location and leave for several hours before returning.
The active ingredient DDV is highly toxic so it is important that you use these trips with extreme care.
What I Like
Designed to penetrate hard to reach areas
The Nuvan Pro Strip’s strength lies in its ability to kill pests that hide in hard to reach places such as nooks and crannies because of its diffusion power. The vapor can penetrate all areas while inflicting damage to the insect’s nervous system.
Effective
It kills all types of common house insects such as ants, bed bugs, spiders, cockroaches, flies, wasps, and earwigs. All of them were gone within two weeks.
Simple
The great thing about Nuvan Pro stips is that they are easy to use. Break the seal, place it in the holder, hand it up, and you are ready to go.
What I Dislike
The product’s shelf life
Nuvan pro strips typically do not last longer than one month active. This is a short shelflife before we need to apply a new one.
Takes Time
For the best results, you will want to leave Nuvan pro strips active for several days.
This means that area with the strip will not be accessible for several days.
If you are looking for immediate results, Nuvan Pro might not be the best choice for you.
Toxic
DDVP is highly toxic, and you need to handle it with care.
No one should be in the same room with a Nuvan Pro strip for an extended period of time for protection.
4. Spectracide Bug Stop Indoor Fogger – Best Fogger
Pros
Kills multiple types of insects
Non-staining formulation
Odorless
Residual effect
Fast and easy
Cons
Chemical composition includes Petroleum Distillate
Flammable
Needs multiple reapplication
Contaminates entire room with pesticides
Key Details
- Type of Killer: Fogger
- Active Ingredients: Tetramethrin (0.10%), Cypermethrin (0.60%)
- How Fast Does It Work: Kills on contact
- How Long Does It Last: Two Hours
How Does It Work?
Foggers are quite simple. Once activated, they will release all the contents inside. This makes the position of the fogger extremely important while it’s active.
The idea behind a fogger is that the content of the bottle will shoot into the air. As the mist falls, the insecticide will penetrate into crevices and eventually attack spiders and other visible insects.
What I Like
Odorless insect killer
Once the room has been fully aired out after treatment, the product doesn’t leave any lingering scent.
Targets All Insects In Sight
The mist, once dispersed throughout the room, will kill all the bugs that come in contact with the pesticide. This is a fast and easy way to treat all the insects in a room.
What I Dislike
Small Coverage
The coverage area of this product’s fogger is much smaller than the usual foggers in the market.
Residual Pesticide
Foggers inject chemicals into the air and through the room that is being treated. These chemicals are not safe for people or pets. Treated rooms need proper cleaning to eliminate any residue.
5. MDXconcepts Organic Home Pest Control Spray – Best All Natural Spray
Pros
Uses natural ingredients
Environmentally safe
Great substitute for pesticides
Pleasant scent
Multi-use: indoors and outdoors
Contact kill
Cons
Cannot eliminate infestation
May subtly leave stains
Its exterminating action is similar to cheap pest control products
Key Details
- Type Of Killer: Spray
- Active Ingredients: Sodium Lauryl Sulfate – 3%, Peppermint oil – 2%, Rosemary and Spearmint Oil – 1% and Inert ingredients – 93%
- How Fast Does It Work: Kills on contact
- How Long Does It Last: No Residual Effect
How Does It Work?
MDXconcepts Home Pest Control Spray is completely safe and non-toxic. It’s made of a combination of essential oils and organic vinegar.
Using these natural substances, the spray attacks the spiders nervous system eventually leading to death. Although it is deadly to small insects, it is safe for children and pets.
When applying MDXConcepts, you must make contact with the spider you are trying to kill. This product does not have a residual effect. So once it dries, there will be no impact on the insects.
What I Like
All-natural ingredients
Derived entirely from plants and organically sourced essential oils. This product is safe for pets and humans.
You can use this product knowing that you are not spreading harmful chemicals inside your home.
Pleasant aroma
In contrast to other odorous pest control products in the market, one advantage of this spray is its excellent and pleasing aroma.
Contact Kill
The benefit of this spider spray is that it delivers a contact kill. There is no wondering whether the spider died or escaped. If the spray comes in contact with the spider, it will die.
What I Dislike
No Residual Effect
Unfortunately, this product does not have any residual effect on insects. This means that you need to continually spray a fresh batch of chemicals on the surface for the spiders to die.
There is no way for the spray to create a protective barrier against new spiders without a residual effect.
Low Knockdown Rate
While it can kill on contact, the knockdown rate is low.
Since this uses all-natural chemicals, the mortality rate is much lower and comparable to low-priced market pesticides.
6. FMC Talstar P Professional – Best Insecticide
Pros
Does not generate any odor
Can be used indoors and outdoors
Non-staining once dried
The product comes in different sizes
The water-based solution that won’t disintegrate easily with rainfall
Can be mixed with other pesticides such as herbicides, fungicides, or liquid fertilizers
Can cover a large area
Easy to handle due to its squeeze and pour design
Cons
When using the product, you should be mindful of the mixing ratios
Should not be used around children or pets
Requires protective clothing to avoid harmful effects from skin contact
Pricey
Key Details
- Type of killer: Insecticide
- Active Ingredients: Bifenthrin – 7.9%, Other Ingredients – 92.1%
- How Fast Does It Work: On Contact
- How Long Does It Last: Product lasts up to three months
How Does It Work?
This product is an all-around rat poison formulated to eliminate home and agricultural pests, including voles, without the need for special traps and poisons.
The formulated pellets contain Diphacinone. It is a popular multiple feed anticoagulant with proven results for almost 25 years. Pellet size ensures maximum absorption of the poison and usually kills rats.
It is also known as highly attractive for its freshness and sweetness in a wax-free formula and long-lasting nugget form.
What I Like
Professional Grade and Powerful
This is a professional grade insecticide that can kill on contact and has a residual effect that lasts up to 3 months.
This is a powerful insecticide that you can spray around your house for ultimate protection against any spiders or other insects.
Residual Effect
The residual effect of this insecticide is what truly sets it apart from the rest. You can create a barrier around your home, and for the next three months, any insects that try to cross that barrier will die.
Economical
There’s no need to buy separate pesticides in case there’s a vehicle infestation. The FMC Talstar P Professional functions just as well.
What I Dislike
Contains strong chemicals
The Talstar P contains potent chemical ingredients; it isn’t safe to use on areas near pets or children. On top of that, it may kill plants if the right chemical-to-water ratio isn’t followed.
Only For Outdoors
The unfortunate thing about Talstar P is that you can only use it outdoors. This means that any infestations inside your home won’t be addressed.
7. Diatomaceous Earth – Best Dust For Spiders
Pros
Safe to use around kids and pets
Also acts as a natural deodorizer
Product can be easily transported
Does not contain any contaminants or additives
Cons
Unable to kill larvae or insect eggs
messy
dangerous if inhaled
Key Details
- Type of killer: Dust / Powder
- Active Ingredients: Fossilized diatoms
- How Fast Does It Work: 3-5 days
- How Long Does It Last: As long as there is no moisture
How Does It Work?
Diatomaceous earth is dust made from fossilized diatoms.
To us, it might seem like normal powder. If you use a microscope, you’ll see something different.
DE is sharp, and it can break down the exoskeleton of an absorb all the moisture until they die from dehydration.
For DE to work, spiders must come in direct contact with it.
This is why it is recommended that you apply DE to areas of high spider activity. This can include under furniture, in small cracks and crevices, or under cupboards.
What I Like
Has variety of uses other than pest control
Aside from its ability to kill pests or fleas from pets, it also has other benefits: a natural deodorizer and an excellent cleaning item that removes stains.
Easy To Apply
DE is easy to apply and to get access to. With a dust bulb you can easily apply dust to hard to reach areas.
Long Lasting
The great thing about DE is that there is no expiration date. As long as the dust is there and there is no moisture it will remain effective.
No Chemicals
DE is a low toxicity powder that does not contain any harsh chemicals.
As long as DE is applied out of sight and in small cracks and crevices where it can not be disrupted and tossed into the air then there are no health concerns.
What I Dislike
Messy
DE can get messy if you are not using the right tools. This can lead to DE getting disbursed into the air which is a health concern.
Slow Acting
DE is not a fast-acting dust powder. It can take between 3-5 days for a spider to die after coming into contact with DE. To see improvements in an infestation, it can take weeks to months.
Conclusion
Effective spider control doesn’t have to be difficult.
With the right guidance and proper execution you can exterminate these pests quickly and effectively.
