Buyer’s Guide

To determine which flea spray works best for your infestation, there are several elements that you should take into consideration. Below, we explain some of the most important factors to keeping flea control in your home.

Ingredients

Flea sprays are either made with synthetic chemicals or natural ingredients. Chemical-based sprays may give you pause if you’re using them on your pets or around your children. However, natural sprays may be more expensive and less effective. If you’re using a chemical-based spray, read its ingredients closely to see what it’s made with. Some chemicals, including imidacloprid, fipronil, permethrin, methoprene, and pyriproxyfen, are known to cause health problems for animals.

Versatility

Some sprays work for more pest control in addition to fleas. They typically target a range of common household insects, including bed bugs, ticksmosquitoescarpenter ants, and spiders.

Application

With some flea sprays, you apply them to the area of your home or yard where you have seen fleas. They typically kill the fleas on contact. However, because they’re usually made from harsh chemicals, you have to leave the area clear for a period of time after application. Other sprays work by killing or detaching fleas that live on your pet’s fur, bedding, and collar.

Quantity

From one-gallon jugs to five-ounce bottles, flea sprays come in different quantities. You can determine how much spray you need by considering how often you plan to use it and how large the flea infestation is. If your pets spend a lot of time outside and you anticipate needing to reapply the flea spray monthly, weekly, or daily, opt for a large container. However, if you have a flea issue in a specific area, you can get just enough spray to treat it.

Results Time Frame

Some flea sprays kill the insects on contact, which can be useful if your dog has picked up a flea and you need it removed right away. However, if you have a large infestation, it may take days or weeks to fully eliminate the problem. Check the description of your flea spray carefully to see how quickly it can produce results for the size of your infestation.


How To Keep Your Pets Protected From Fleas

Flea spray is an essential item for any pet lover whose dog or cat spends a lot of time outdoors and lives in an area that’s highly susceptible to fleas. However, flea spray alone may not be enough to keep your furry friend safe. Here are some other steps our team recommends you can take to prevent and get rid of fleas.

Keep Your Home and Yard Clean

Changing your linens, vacuuming and mopping your floors, and wiping your counters limit the risk of fleas getting into your home. You should also maintain your yard, as mowing the grass, pruning the bushes, and removing the fallen leaves give fleas fewer places to set up camp.

Check Often

Any time your dog or cat spends a significant amount of time outside or displays unusual behavior, check their fur and skin for ticks right away. The more often you complete a thorough check, the more likely you are to catch the fleas early before they can become a bigger issue.

Consider a Flea Collar

With approval from your vet, a flea collar can help repel and kill fleas. Flea collars should fit firmly around your pet’s neck, touching their skin without constricting their breathing.

Be Careful in Warm Weather

Fleas are more prevalent during the warmer months of the year, so you should be especially careful with your pets during the summer. Try to limit the amount of time your pet spends outdoors in the heat of the day and at dusk and dawn.

Brush Your Pet With a Flea Comb

Brushing your dog or cat with a flea comb can help remove attached fleas and eggs from their fur. Keep a bucket of warm water by your side whenever you use a comb so that you can quickly drown any fleas you come across.


Frequently Asked Questions

Are flea sprays harmful to pets?

Many flea sprays are made with safe plant-based ingredients, but others contain chemicals that can cause allergies or sicknesses. To determine which type of spray you have, read the product description. If your pet displays concerning symptoms, such as skin irritation, sneezing, vomiting, diarrhea, or watery eyes, it may be a result of your flea spray, so wash it off immediately.

Does flea spray stain carpet or upholstery?

There’s a chance that your flea spray could leave a stain on your furniture or carpet depending on the spray’s formula and the surface’s material. However, the product should clearly state on its label whether it is non-staining and can be used as a carpet spray.
