Because fleas and ticks are so good at what they do, you will need to be extra vigilant during the peak flea and tick season -- typically the warm weather months from spring through early autumn (in the southern states, flea and tick season can be all year long). If you notice just one or two insects on your cat, treat it seriously, before it becomes a full blown infestation.
If your cat is very young or old, or if he has any underlying health condition, visit your veterinarian for advice on the best preventive medications and the safest way to use them. Your doctor will be able to show you the proper way to apply these medications and recommend just the right dose for your cat’s age and weight. If you catch the problem quickly enough, you may be able to avoid chemical solutions and try natural solutions first.
For the outside, there are some plants that are known for their flea repelling characteristics, and it is worth it to try anti-pest landscaping. But it is often easier and more effective to use chemical pesticides and repellants for yard and perimeter treatment, especially when dealing with an infestation that is already in full progress.
If you do already have a flea and tick problem, you might want use the tried and sure chemical remedies for this year, so that you can comfortably enjoy the rest of the season, saving your reliance on flea repelling landscaping for next spring. It’s much easier to start early, keeping parasites from getting a foothold, than it is to try to eradicate them after they have had a chance to breed and establish themselves in your home and on your pet.
