When you’ve got creepy crawly spiders hanging around your house, but you can’t pinpoint where they’re coming from or hiding, what can you do?
You could go hunting with a point and spray can of your favorite spider killer and hope to find one of them, or you could take the easier softer way and use a spider bomb or fogger.
Today, we have five different bombs and foggers for you. Some are traditional bombs, others are anything but. We’ll look at:

NuVan ProStrip are a slow-release method of fogging an enclosed room, closet, or other small area. While the strips are releasing their payload, neither you nor your pets or children can be in the room while it is working. Think of it as a small-scale method of fumigation.
NuVan ProStrips have been successfully used to kill Brown Recluse spiders in closets. They have also proven to be effective in tight spaces that are packed with boxes and furniture. The gas slowly penetrates into all the cracks and crevices.

What Are Spider Bombs and Foggers?
The words “bomb” or “bombs” and “fogger” are often used interchangeably but in fact, they describe somewhat different devices. The intent of both of them is the same; to create a cloud of a visible or invisible gas that will kill insects that are within the cloud. Or in our case today, spiders.
The method of delivery is what makes the difference. A bomb is any device that, once triggered, continues to release the payload of toxic pesticides until it has exhausted its contents and nothing is left. Like a real bomb, once it is triggered there’s no way to stop it.
A fogger is any other device that creates a cloud of pesticide. The difference being that the action of a fogger can be turned on or off, continued or discontinued at will. A fogging device may or may not include the pesticide itself. Professional pest control experts generally expect the two to be separate but some manufacturers combine them for sale to the general public.
Spider bombs and foggers are a way to fill large cubic feet of air in a room with pesticide to kill spiders such as black widows and brown recluses, scorpions (members of the arachnid family), and other crawling insects.
The best spider bombs also exterminate:
- Bed bugs
- Black carpet beetles
...to name a few! The fogging process will also kill flying insects such as houseflies and take care of any flea problem you might have.
In other words, although the best spider bombs are intended for spiders, they’ll handle other pest problems too.

How Do Spider Bombs and Foggers Work?
Total release foggers (foggers or bug bombs) work by filling the air with microscopic particles of pesticide in a vaporous cloud. In this form, it seeps into every crack and crevice in a room or rooms where spiders (such as a brown recluse) might be hiding.
Because bombs and foggers create a spreading cloud, they can reach the hiding spots where bugs live and quickly stop an infestation before it becomes serious. Bug bombs can reach into the depths of storage areas, under appliances, and behind cabinets.
There is one serious side effect associated with even the best bug bombs – flammability. An aerosol spray is highly flammable. If you spray it around the pilot light on your stove, hot water heater, or HVAC, it could start a serious fire in your house.
The NuVan ProStrips is the only one on our list that doesn’t suffer from this serious drawback, and it’s a big part of the reason we like it so much.

How Do You Find The Best Spider Bombs and Foggers?
The best spider and other bug bombs are those that use professional-grade active ingredients such as:
These have been tested by the Environmental Protection Agency (EPA) and regulated as safe.
Additionally, we’ve used many of these products out in the field ourselves as pest control technicians. We know from practical on-the-job training what works and what doesn’t.
Are Spider Bomb and Foggers Effective?
Yes. However, bombs and foggers intended for professional use tend to be stronger than those for the general public. The active ingredients, the ones that do the killing, aren’t overly diluted in professional products
Over-the-counter products are usually diluted, mainly as a way to avoid lawsuits. So, although many products contain the same active ingredient(s) as professional products, the weaker strength means they don’t work as well.
Using professional-grade products requires you to follow the product label to a T. The end result is worth the.
A spider infestation, or any insect infestation, requires an aggressive response and you can’t do that with diluted products.
How To Use A Spider Bomb and Foggers
In order to achieve maximum penetration into all the cracks and crevices where bugs and spiders might be hiding, open all the cupboard doors, all the closets, all the drawers in the kitchen, bedrooms, bathrooms – anywhere you’re going to be using the bug bombs and foggers.
If spiders have made themselves at home around the A/C or hot water heater, turn off the pilot lights on each of them and leave the closet door wide open so the fumes can penetrate.
Close all the windows in the room (or house) to prevent the pesticide from leaking out. If you’re using a traditional bug bomb, start them one at a time as you back out of the house. No one (humans or animals) should be in the house while the bombs and foggers are working.
You’ll need to wait at least two hours for the fumes to dissipate before re-entering. Check the product label for specific guidelines. If you’re using NuVan ProStrips the waiting period will be 5-7 days.
Once you’re back in your home, you might need an odor neutralizer of some kind. Many pesticides leave a chemical smell in the air after they finish working. This is particularly true with total release foggers such as traditional bug bombs.
Be sure to wipe down the kitchen counters and food preparation surfaces so eliminate any lingering pesticide that might find its way into your dinner.
Finally, throw the pesticide cans away. Don’t try to re-use them or shake them to get the last little bit out.

Are Spider Bomb and Foggers Safe Around My Pets And Children?
No. Pets and children, especially little children, have immature lungs compared to adults. The aerosol fumes can be very hazardous to them and to us. Never let them enter an area while it is being treated or immediately afterward.
Wait until the fumes are completely gone before letting children back in. The same thing goes for pets.
Best Spider Bomb and Foggers Reviewed
NuVan is a little-known indoor-fogger that works by the slow release of its active ingredient, Dichlorvos. Dichlorvos is a cholinesterase inhibitor that inhibits the action of certain chemicals in the central nervous system.
NuVan strips come sealed in a foil wrapper. When the wrapper is peeled off, the strip is put into a plastic hanger where it begins releasing its vapors into the air. One strip will fumigate 10 cubic feet of space. The drawback is that it takes 5-7 days to completely fumigate a room.
While the NuVan strip is doing its work, the room needs to be completely sealed so the gases don’t leak out. They will penetrate every crack and crevice of the room, killing every spider and insect in the room.
This is a hand-held aerosol spray fogger. Hold the can in one hand and press the button on the top. Continue holding it down to spray the areas where you’ve seen spiders in your house. The fog will spread out and penetrate the cracks and crevices.
Don’t forget to fog the corners of the room up by the ceiling where spiders like to make their webs.
This aerosol spray from Black Flag uses Prallethrin and Lambda-Cyhalothrin (both pyrethroids) to kill spiders of all kinds. Contrary to the product description on Amazon, it does not kill anything “on contact.” A pesticide that strong would be dangerous.
This is a small area spider fogger for enclosed spaces like closets, cupboards, and small rooms. Although technically it is a fogger, it should be used like a directed spray.
The active ingredients in it are diluted more than they need to be. The action will be slow compared to other methods that kill spiders.
As with all pesticides, follow the label directions carefully each time you use it.
Made for fogging orchards, this electrical, corded backpack fogger can easily be used indoors to fill a room with insecticide fog to kill spiders. Any good pesticide can be put into the fogger to kill the spiders in your house.
We recommend using Suspend SC, a pyrethroid-based insecticide, using Deltamethrin as its active ingredient. Mix the chemical according to the directions on the label, about 0.75 ounces per gallon of tap water in the tank and strap it on.
You’ll need to wear a respirator, of course, but you’ll get excellent coverage to get rid of the spiders. Keep the nozzle about five feet from any surface to prevent moisture from beading up and running down the walls, creating streaks.
This is a traditional “bug bomb” fogger. Each one will treat about 10-15 cubic feet so you’ll need multiple bombs to kill all the spiders in your house. Open all the cupboards and close all the windows and doors before triggering the bombs.
Space the bombs equally in each room you’re treating. Start them and quickly leave the room, shutting the door behind you. Stay out of the room for at least two hours to give the insecticide a chance to work.
Our Top Pick: NuVan ProStrips
NuVan ProStrips is our top pick. Even though it is slower to work than the other spider bombs and foggers listed, it has a much higher success rate than any of them. It’s as close to 100% effective as possible.
Short of putting a tent over your whole house, this is the closest thing to total fumigation available today.
And if you need to get rid of spiders in your car, this is by far the best solution. Cars are nearly airtight anyway and all you’ll need is one NuVan strip to completely fumigate your vehicle.

- Nerve gas for spiders
