However, flea infestation may occur in houses without pets, too.

The bumps due to flea bites may be painful and itchy, causing significant discomfort to the child. But, constant itching may increase the risk of secondary infection. Timely diagnosis and treatment of flea bites are important to prevent secondary infection.

Prevention Of Flea Bites In Children

The best way to prevent flea bites is to minimize your child’s exposure to them. Here are some measures that you can observe.

1. Locate the flea source and kill them with anti-flea insecticides. Extermination is necessary as fleas reproduce rapidly, and curbing their growth becomes extremely difficult. You can find fleas in your doormats, carpets, or couch. Alternatively, they can be on your furry pets, such as cats and dogs, and in your yard, construction sites, and woody areas with tall grasses.

2. Clean the suspected indoor areas and items. As soon as you locate the area, prepare for its sanitization. For instance, you can vacuum clean rugs, couch liners, doormats, carpets, and all the other fabrics that you suspect are infested with fleas. It will help remove flea, flea eggs, and droppings. Alternatively, you can steam clean or shampoo the fabrics and use boric acid powder to prevent flea from reproducing.

Two Crazy Cat Ladies, a YouTube channel belonging to two cat-lovers from the US, mention in their vlog how the manifestation of fleas in their homes, or more specifically rugs, can be stopped. They explain, “In order to safely remove fleas from your home, you would want to stop the cycle. Flea eggs can go dormant in your carpet and hatch with the smallest vibration, which will start the cycle again, so you will need to treat your house even after you no longer see the fleas. Vacuum the carpets in your home daily and use safe natural flea treatments, both for your cats and in your home. Be consistent as it can take several weeks to break the cycle, but you can do it naturally with these tips (i).”

You could also vacuum all the crevices around baseboards, behind doors, and under furniture, cabinets, and appliances. Throw off the vacuum bag immediately once you finish cleaning.

3. Consider pest control indoors and outdoors. For instance, you can treat your home with insecticides using a hand sprayer, aerosol can, or room fogger. Alternatively, you can book a professional pest control service and let them clean the house and yard thoroughly. Here, you should note that the flea pupae don’t get affected by the insecticide. So, you may see some adult fleas in your house for up to two weeks after the treatment.

4. Talk to your child’s school or day-care facility if you suspect that the child may be getting flea bites there. While the organizations take the necessary measures to locate and combat fleas, go a little further and dress your child in weather-appropriate clothes that cover their exposed body parts, such as arms and legs.

You can clothe your child in full-arm shirts, socks, gloves, and trousers. Additionally, tuck in their shirt in their trousers and their trousers’ legs into their socks or shoes. Follow this practice even when you take your child to play outdoors.

5. Consult your healthcare provider regarding insect repellents. The doctor will suggest some non-toxic, child-friendly insect repellents that the child could wear on their skin or spray on their clothes. Fabric roll-ons are another good option. Teach your child to use insect repellents whenever they step out of the house.

6. Keep your pets flea-free. To know if your pet has fleas, observe them. For instance, if you notice your pet continually scratching themselves, especially when they spend a lot of time outdoors, there’s a high chance that they have fleas. Furthermore, if you notice salt and pepper-like mixture on your pet’s bedding or red scabs on their skin, they may have fleas. In such a scenario, consult a veterinary doctor and seek advice to treat your pet. The doctor may

Note: Buy anti-flea products that are labeled for a particular pet. It means if you buy a dog-oriented anti-flea product, use it only on dogs and not cats. Also, keep your child away from anti-flea products and pets that have just been treated. If they want to tend to the pet, ask them to wear gloves.
