Traditional methods such as direct contact sprays, or even home remedies like lavendereucalyptus, etc. may work in the short term to remove these unwanted guests.

Still, if you can’t get to the source of the problem, it will be a constant uphill battle to get rid of them.

In this article, we’ll be looking at the best spider bombs available on the market and how to effectively use them, along with some of the key considerations when using a spider fogger.

What is a Spider Bomb?

Spider bombs, also commonly known as spider foggers or bug bombs, are a total release fogger containing pesticides that are release using aerosol propellants to fumigate a vast area such as a basement, apartment, or attic.

The difference between a contact spray and a bug bomb is that all the pesticide is released on application to cover the broadest possible area and the penetration of all the nooks and crannies.

Do Bug Bombs for Spiders Work?

So the short answer is YES. When they are used correctly for their intended purpose, they do work.

As long as you do not have a severe spider infestation requiring a professional pest removal service, spider bombs work well. The commercially available spider fumigation bombs for use in the home can be very effective.

What If There Is Heavy Spider Infestation?

If there are many spiders, you may find it challenging to get rid of them using a few bug bombs in your house.

In that case, I recommend taking the help of an exterminator. They (most of them) are professional, and you will be delighted after seeing a pest-free house. So, if you can afford an exterminator, hire one.

How to Use Spider Bomb in House

As with any do-it-yourself product, when used correctly, they can be highly effective. However, when misused, they can be extremely dangerous.

Spider foggers can pose a severe risk to your family; these can even include respiratory and gastrointestinal ailments. Before using any total release fogger in your home it is critical that you follow these safety tips and precautions:

#1 – Follow All Directions on the Product Label

Pesticide manufacturers are required to include important safety and usage information on the product label.

To understand the risks and proper usage of the product, you must read all of the sections on the label, i.e. dangers of the product, poison information, warning descriptions, etc. very carefully.

#2 – Use the Correct Number of Spider Bombs

Pesticide manufacturers test their spider bomb products to determine the safest and most effective amount of pesticide to use per square foot of target space.

Using more spider bombs than is recommended by the manufacturer is a waste of money and increases the health and safety risks of using these products.

#3 – Cover all Exposed Foodstuffs and Children’s Toys Before Use

It must be remembered that once you set off a spider bomb in your home, the pesticide will fill the room and then eventually settle on all surfaces.

Always cover or remove any foodstuffs or toys which may be exposed; this is especially important for small children as they tend to put their toys and other objects in their mouths.

Put exposed foods in the refrigerator or sealed containers, or use garbage bags as temporary storage for the toys the child may play with.

#4 – Unplug Any Appliances

The aerosol propellants used in spider bombs are incredibly flammable, and more often than not, people tend not to see the potential dangers this may pose.

A random spark may ignite the fumes in the air causing untold damage to your home and possessions.

As a thumb rule, always unplug any appliances, refrigerators, and air conditioners within the room or rooms to be spider bombed. If you use gas, make sure the pilot light is off.

As an additional safety precaution, always try and place the spider bomb at least six feet away from any potential source of a spark to avoid the propellant’s accidental ignition.

#5 – Vacate the Premises

This may be considered a no-brainer, but you would be surprised how many people simply ignore this critical step in using a spider bomb.

Remaining close to an activated spider bomb is a massive health risk, and exposure to the pesticide must be avoided at all costs.

Simply put, make sure you have a quick and easy exit from the room or house in place before you set off the spider bomb. Don’t think that using a fogger in your bedroom during the day will allow you to sleep there that same night.

#6 – Stay Away (Per the Product’s Instructions)

Depending on the brand and product used, you will need to vacate your home or premises for several hours before returning after you have activated the spider bomb.

Returning home early may pose a health risk as the pesticide has not had a chance to settle and is still in the air.

Instead, plan a date and time to use the spider bomb/s when you are away for some time, perhaps a dinner date or taking the kids to the park or other recreational activity.

Stay away from the premises for the minimum time indicated on the product label.

#7 – Ventilate the Area Well Before Entering

After the recommended time as indicated on the spider bombs label, open all the windows of your home for a minimum of one hour to ventilate the area properly.

It is recommended that family members not enter the house until after this one-hour period to ensure that any remaining airborne pesticide dissipates.
