Best Flea Carpet Powders & Sprays Buying Guide
What to Consider When Buying Flea Carpet Powders & Sprays
There are plenty of products out there so here is a list of what you should look out for when choosing the best flea powder for you.
- Flea powder or spray: The best one for you is a matter of personal preference. Some people find sprays messy but they are quick. Powder application takes a little more effort.
- Where you want to treat: Choose the best product for the area you want to treat. Some are designed for spot treating small areas whilst others are for whole rooms.
- Odor control: Many owners choose a product that contains an odor control ingredient to leave their house smelling fresh after the treatment.
- Length of action: Some treatments last for a few weeks but others remain active for months.
Can Flea Powder Kill Fleas Immediately?
Even the best flea carpet powder and spray cannot start working until it actually comes into contact with the fleas. Once that happens, many of the commercially available home flea treatments will get to work straight away. The powerful insecticides such as Pyrethrins are very fast-acting and you should soon start to see results. This is especially welcome if you have a heavy infestation in your home and need some immediate help.
However, this is not enough because the fleas will have laid eggs. You need a product that remains active and that will tackle larvae as soon as they hatch.
How to Properly Use Flea Treatment for Carpet
Each carpet flea powder and all flea carpet sprays come with their own detailed instructions. Because each product contains different active ingredients and different concentrations of active ingredients, you should read the instructions and follow them carefully. Most flea carpet powders are applied by shaking the container to get an even coating on all parts of the carpet. They require you to brush the powder into the carpet using a broom. This is to make sure that the product is worked deeply into the carpet where it will come into contact with fleas.
Then, it has to be left for a 'contact time' during which it will act on adult fleas and larvae. The 'contact time' will vary between products and you may not be able to walk on the carpet whilst it is working. The powder is removed by vacuuming.
Flea carpet sprays are applied by directing the aerosol or nozzle to deliver droplets onto the carpet. Don't forget those hard-to-reach areas.
It is very likely that you will have to reapply the flea treatment after an interval because you want to make sure that you kill newly hatched eggs. The manufacturer will give a recommendation for reapplication.
Flea carpet spray treatments and powders contain powerful chemicals and you must be careful that you do not get them in your eyes, ingest them or breathe them in. If this happens, follow the instructions on the label and seek medical advice. Always follow the precautions regarding keeping pets away from the treated area for a period of time.
A top tip is to treat areas where your dog spends the most time with more flea carpet spray or powder and more frequently.
Best Flea Carpet Powders & Sprays FAQ:
Q: What are flea carpet powders?
A: Flea powders that can be applied to a carpet would be used when you suspect that fleas are living in your carpets and rugs. This is a problem because they will continually re-infect your dog or cat. You must tackle the infestation on the animal and in your carpet at the same time to be successful.
They come in the form of a fine powder that can be sprinkled directly onto the carpet. Most are left for a while to work and are then vacuumed up.
Q: How do flea carpet sprays work?
A: A flea carpet spray or powder works by interfering with biological mechanisms that the flea relies on to stay alive. Different chemicals do this in different but here are some key examples.
Pyrethrins are found in many of the products listed in this guide. They occur naturally in chrysanthemum plants and there are several different types. Pyrethrins act on the nervous system of parasites and causes it to go into overload - this causes death. The mechanism does not just work on fleas, it also works on lice, ticks, some mites, and mosquitoes.
Pyrethroids are another common constituent of flea carpet spray. They are able to kill fleas because they act in the same way as pyrethrins on the insect nervous system. They are not a naturally occurring group of chemicals but are manufactured in laboratories. The speed of action is slower but the effect lasts for longer.
There is another group of insecticides, the insect growth regulator group, which kills fleas that have not yet developed into adults. This group includes methoprene, fenoxycarb, and pyriproxyfen.
Finally, some treatments kill fleas by inhibiting their ability to synthesize chitin. They fail to form a hard cuticle and basically shrivel up. These need to be used with another preparation that kills adult fleas.
Q: How reliable are flea carpet sprays and powders?
A: Modern products are highly effective but must be used in conjunction with other methods of control if you are really going to get on top of this problem. Always use them according to the manufacturer's instructions to get the best out of them.
As well as treating carpets and soft furnishings, you must also treat your dog or cat as they are the host for fleas. It also helps if you maintain high standards of hygiene and cleanliness in your home and in any outdoor space that you have.
Q: Do they pose any health risks to my pets?
A: All types of flea powder and spray have undergone extensive testing to make sure that they are safe. However, you must exercise caution when you are using them. If you get them in your eyes, if you inhale a large amount or if you ingest them, you must seek medical attention.
Pyrethrins are easily broken down by the stomach so they are considered low in toxicity. Pyrethroids are more toxic because the gut cannot break them down as quickly.
