Knowing how to prevent fleas from living on your cat or dog is incredibly useful because there’s no doubt about it: fleas are a nuisance. They can make your pets itchy and uncomfortable, they carry tapeworm, and they can even transmit illnesses to your human family members. It's absolutely vital that you take some action to prevent them, be it the best flea treatment for dogs, or the best flea treatments for cats, along with following the six tips we've outlined here.

Once a female flea hitches a ride on your pet, she can produce 40-50 eggs per day, and can survive more than 100 days. Before long, you’ll have a major flea infestation on your hands. Maintaining your pet on flea prevention medications year-round is the best way to prevent fleas, but there are other steps you can take to ensure fleas stay out of your home. Managing the environment will ensure your home no longer looks warm and cosy to those invading fleas!

Check your pets for fleas regularly

It only takes one flea to start an infestation! Unfortunately, by the time many pet owners start noticing fleas, their living space has already become home to thousands of them. Checking your pets regularly will help you spot a problem early, so you can get it under control right away. Use a fine-toothed flea comb to look for signs of fleas in your pet’s coat. In addition to live adult fleas, keep a close eye out for flea faeces, also known as “flea dirt”, which looks like small black flakes or clumps. Finding any fleas or flea dirt is a sure sign of an infestation in your home.

1. Make sure every pet in the home is protected from fleas

Don’t forget that indoor pets can be exposed to fleas, too! Fleas and flea eggs can make their way into your home on other pets or even on your clothing. In apartment buildings, fleas have been known to accumulate in common areas, or even travel from apartment to apartment. Once inside your living space, they reproduce rapidly as long as a viable host is available. Keeping all your pets on flea and tick prevention year-round will help discourage fleas from establishing themselves inside your home. Your veterinarian can help you choose the best products for each pet in your household. With a variety of collars, topical treatments, and oral medications on the market, you’ll be sure to find the right products to meet everyone’s needs.

2. Treat problem areas like gardens, crevices, and crawl spaces

Flea larval cocoons are extremely hardy, and can survive in the environment for up to a year. Adult fleas will emerge from the cocoons when environmental conditions are just right. Their emergence is often triggered by warmth, movement, and carbon dioxide – all the things your pet provides as he or she passes through their hiding place! Once the adults emerge, they can rapidly reproduce and create a new infestation. If you live in an area where fleas are particularly prevalent, treating the places that may be harboring flea eggs and larvae can help prevent fleas from affecting your pets. Consider spraying your garden, under decks and sheds, inside crawl spaces, and any other cracks and crevices around your home. Just be sure to read the label on any flea control product to ensure it is safe for use around pets.

3. Clean carpets and bedding regularly and thoroughly

Adult fleas lay eggs on your pet, which then drop off into the environment. The fleas then complete their life cycle in the environment, safely ensconced in your carpets and upholstery. These hidden flea eggs and larva can be a constant source of infection for your pet. Frequent cleaning of high-traffic areas – especially those where your pet likes to hang out – can help reduce the environmental flea burden, and prevent new adult fleas from re-infesting your pets. Vacuum carpets and upholstery frequently, and wash your pet’s bedding in hot water. For added protection from fleas, sprinkle borax or flea powder onto the carpets before vacuuming, and add some to your vacuum bag to prevent fleas from crawling back out.

4. Keep your guests flea-free to protect your pets

Your pets may be protected, but the pets of friends and family members who visit your home may not be. These furry friends may be bringing unwanted guests when they come to visit! Ask your guests if they’re using flea prevention before they bring their pets over to play. Make sure your pets are protected from fleas too before allowing them to interact with the newcomers or passing through areas where they’ve been. After the visit, be sure to thoroughly clean the areas where an unprotected pet was resting or playing. 

5. Bring in the professionals to prevent fleas

Once a flea infestation starts, it can be a nightmare to stop. Professional pest control services have the experience and equipment necessary to stop active infestations and prevent new fleas from establishing themselves in your home. They can also help you identify problem areas in your home, and advise you on the safest ways to use flea control products around your pets. Many companies also offer follow-up services to check your property during peak flea season. Professional services can be expensive, but they are often easier and more cost-effective than trying to tackle the problem on your own. 

6. Year-round flea prevention: The best way to keep your pet flea-free

Ultimately, the quickest and easiest way to prevent fleas is to keep your pet up-to-date on flea prevention year-round. Prescription flea preventives are readily available, and with many varieties on the market, you’ll be sure to find something that fits your budget and lifestyle. Using prevention products recommended by your veterinarian will ensure fleas never have a chance to infest your pet, so you can rest easy knowing they are flea-free!
