Buyer’s Guide

It’s no secret: Fleas are a threat to your health and that of pets – that is evident with flea dirt lying around. In fact, Chigoe flea acts as intermediate hosts for parasitic tapeworms and cause skin allergies. However, fleas live on human skin only for a short time (about 7.5 minutes).

Therefore, target the bugs in their hideouts, yard and pet skins. Also, vacuum rooms before fogging to remove debris, flea eggs, and larva & stimulate flea larvae to change stages. You can use the best bombs for fleas in enclosed spaces such as offices, restaurants, apartments, garages, and other residential areas. 

How to Bomb Your Home for Fleas 

What Safety Precautions Should You Consider?

But, do they work? Many people use Fleas Bombs (also known as flea foggers) to kill fleas and insects in their homes. The active ingredients in flea foggrs are S-methoprene, IGR (Insect Growth Regulators), pyrethrin, tetramethrin, and cypermethrin.

But, Do Flea Bombs Ever Fail To Work?

The only time that foggers do not work is when you put only a small amount of these bombs in a very large area or, the fleas have started to build resistance for these chemicals.

Best fogger for fleas contain chemicals that kill adult fleas and hinder the growth of eggs. For flea bombs to be effective, you’ll need to place the correct number of canisters for the size of the area you want to deal with.

  • You can be infected if you forget to clean your yard. We must remember that your dog spends most of the time in your yard beside your home. Therefore, besides your house, you should also treat your yard.

Flea Bomb Alternatives

1. Flea Combs 

Besides best bombs for fleas or you can use a Cat Flea treatment or Dog Flea shampoo. However, if you have a feeling that your dog or cat has fleas, you can get a flea comb for cats (or even the Electronic Flea Comb) and run it through the fur of your pet.

After doing it, you will see the fleas out from the fur and in the comb indicating their strong positive presence. You may also use dawn dish soap to kill and repel fleas.

You can also check for more fleas by looking into black specks into the fur and skin of your dog. If there are indeed, then it’s time to act. In the battle against these creatures, time really plays an important part.

There are alternative treatments for fleas, but regardless of the treatment that you use, you should not forget to comb your dog with a flea comb thoroughly in order to remove as much of the fleas, feces, and eggs as possible.

While combing the hair of your dog, you should have a standby bowl with you so that you can have something to place the contents of the comb after. Once you’re done, you could drown the remaining material into the toilet.

2. Flea Collars

The use of flea collars, powders and lotions are other options that you can try for your dog. In fact, you can try them all.

You could also combine these natural methods with the use of foggers that have also proven to be effective in eliminating fleas in the entire house.

3. Diatomaceous Earth (DE)

There is no doubt that DE plus borax is an excellent natural flea control method that can offer all year round protection against fleas.

You’ll need to sprinkle the DE powder in the pet houses. Further, do not assume that locking your pet will prevent fleas from infestation. It is important to control the fleas inside the pet house too.

4. Pesticide Sprays

Pesticide sprays kill fleas and are suitable for home use. Watch out for ingredients such as resmethrin and permethrin, which is not good in cat flea treatment. Ensure that any spray you use will kill the flea eggs on cats.

Sprays can be a good alternative especially for those hard to reach areas in your home. Just follow the instructions on the label to achieve better results.

5. Vacuuming

The combination of pesticide sprays and vacuum is another effective method of removing fleas from your home. Areas such as those under the bed, furniture and even hard to reach areas cannot be treated.

Vacuuming these areas will ensure that no traces of dead fleas and eggs will remain. You can also use flea traps to get rid of fleas. There are many brands of flea traps available in the market. Light easily attracts fleas. Set up the trap near a lighted area. However, flea traps only kill adult fleas. 

Do Foggers Kill Fleas Instantly?

Yes, most foggers do kill adult fleas instantly i.e. within a few seconds – particularly for a massive flea infestation. But the fogger will continue killing the fleas for up to 8 months (long residue effect) in your home. Flea bombs with IGRs like S-Methoprene in Precor Plus will also inhibits the flea’s life cycle killing the flea larvae and their eggs. However, vacuum the carpet and floors thoroughly within 2 weeks after the initial treatment to remove flea eggs and flea dirt.

A small indoor space will require fewer foggers as the mist will easily reach all the hidden areas. Also, ensure you block all the spaces leading outside including cracks, doors, and windows where the fogger mist would escape.

How Do I Get Rid Of Fleas in My House Fast?
