User Criteria For Buying Bug Bombs for Spiders

Before you jump the gun, here are a few things to consider when buying a bug bomb for spiders.

Targeted Use

Some of the best bug bombs for spiders available in the market are listed above. The best spider bombs kill spiders immediately upon contact as well as offer a barrier against re-infestation for several months. These foggers don’t just get rid of your arachnid problem, they also target other pests like cockroaches, silverfish, ants and even scorpions, in some cases. However, since they are targeted to kill spiders specifically, they may not be as effective against other insects.


Most spider foggers contain harsh chemicals that are toxic to humans and animals. They also contain smelly, toxic fumes that can cause discomfort to anyone in the vicinity. When buying spider foggers, make sure you buy the ones that contain natural, toxin-free ingredients. However, when it comes to pesticides, natural ingredients aren’t always very effective, so make sure all people and pets in the house vacate the building before you apply the spider bomb.

Let them in once the spray has dissipated. Also, keep the product away from children and animals. If the chemicals get on your hand, thoroughly wash with soap and water. In case of irritation, go to a doctor immediately.


Although many bug bombs for spiders are filled with chemicals, there are some options that are not as harsh as others. These also do not emit any harmful odor that can disturb your family and are made of partly organic ingredients. You can choose these instead of purely toxic spider bombs. Also, remember that most aerosol sprays are flammable, so don’t spray them near a lit flame.



Spider killer sprays are relatively affordable; however, there are some brands that cost more than others, because of superior quality. While making sure that you buy a spider fogger that fits your budget, don’t compromise on effectiveness and performance.

Buy a spider bomb that suits the need of your home. Since spider infestation is not too common and often not that large, keep in mind that a single bottle can last you a long time.


Q: Are spiders very harmful?

A: Although most household spiders are almost completely harmless, there are some species that are extremely lethal, like the infamous black widow, brown recluse and the Hobo spider. These spiders have a venomous bite that can harm humans and animals. If you have small pets and children at home, there is good cause to be concerned.

Q: Should I worry if there are spiders in my home?
A: Generally, having a large number of spiders in your home points to an infestation of another kind. Arachnids live in areas where there is plenty of food, so it means your home as other pests as well, like bed bugs, fleas, roaches or silverfish. Fortunately, many spider foggers work on these pests too, giving you great value for money.
Q: Do bug bombs for spider work?
A: In short, bug bombs for spiders work very well for small to moderate infestations. However, there are some products whose fumes cannot penetrate cracks and crevices, where spiders live. A lot of mist also ends up falling onto table surfaces and carpets. If you have a larger infestation and the spiders are out of control, call an exterminator.
Q: Are spider bombs safe to use?
A: Since many spider killer sprays contain chemicals, they can be dangerous for both children and animals. Some spider bombs contain the active ingredient, pyrethrin, which may be relatively harmless to humans and dogs but not to smaller animals, like cats. Also, as mentioned above, many of the spider bombs are broad-spectrum, meaning they can harm non-targeted insects as well.

This is good news if the insects are harmful pests like roaches ants and scorpions, but not so much if they are harmless flying insects like moths, butterflies, and bees. Therefore, whenever you are buying a spider bomb, make sure you read the instruction label’s carefully and minimize harming other beneficial species.

Q: What are some dangers of spider foggers?
A: Spider bombs contain chemicals that can be harmful to children and pests. If you are present during fumigation, you may experience dizziness, asthmatic symptoms, and nausea. Aerosol sprays are also quite flammable, so be wary of open flames around the house during fumigation.
