Eliminating fleas from your house can be a challenging task because these pesky creatures find difficult-to-access areas to hide.

Therefore, you will need to target all these congested regions to get rid of fleas from your home. Keep reading to know what you can spray for fleas in the house and learn about some best products.

What Can I Spray in the House to Get Rid of Fleas?

Regular inspection and early detection are critical for preventing fleas from infesting your house. Once these parasites are identified, it’s important to respond immediately and kill them before they could multiply themselves. The following are some treatments that can help you keep your home flea-free.

Citrus-Based Sprays

These low-toxicity treatments are ideal for indoor use because they are not dangerous for kids and pets. They contain chemicals like linalool or limonene that can be safely applied to carpets and bedding. These sprays are ideal for killing adult fleas but won’t provide a lot of protection against re-infestation. This is because they evaporate quickly and can’t eliminate fleas in egg or larvae form.

Boron-Based Products

This method is only effective against immature fleas because it works by contaminating their food supply. Adult fleas live on fresh blood and boron-based chemicals, such as Disodium Octaborate Tetrahydrate, won’t be able to kill them. These products don’t cause any damage to furniture, carpets, and rugs and offer a safe alternative for indoor use. However, they can cause some skin toxicity and are not recommended for people with sensitive skin.

Insect Growth Regulators

These sprays are very useful against fleas and some pest control companies also use them for treatments. The most common of these regulators are Pyriproxyfen and Methoprene. Both of these chemicals can be used to spray for fleas in the house. Pyriproxyfen is effective against adult as well as immature fleas and can also be used outdoors. On the other hand, Methoprene can’t withstand direct sunlight and is only beneficial for indoor use.

How to Use a Household Flea Spray?

It’s necessary to make appropriate preparations before applying a spray for fleas in the house. For example, you need to remove all the pets from the room or the house, depending on the scale of infestation. Similarly, you need to ensure that there is nothing on the floor, like toys, on which the spray can stay. This is because it might get contaminated and can make you (or the kids) sick. You also need to close all the doors and windows to stop the chemical from escaping the desired vicinity. Last but not least, these sprays are highly flammable and you must keep them away from naked flames.

Once all these preparations are done, you can spray the chemical to kill fleas. A safe method to do so is as follows.

  • Shake the can well before spraying.
  • Hold the can upside down and spray around the area you are trying to treat.
  • You should spray directly on the floor or carpets to kill the fleas.
  • Spray the region well but don’t overdo it. The general rule of thumb is that a 5-second burst is enough to cover 1 square meter.
