Ideal Conditions for Fleas & Ticks

Regions with increased humidity levels, between 50 and 90% are ideal for fleas and ticks. They favor warm weather and are less active in colder times of the year. These parasites thrive in temperatures that are 70°F or higher. It’s worth knowing that adult fleas can stay in the cocoon for up to five months. Whereas flea eggs, larvae, and pupae remain alive throughout the year. Ticks too have been known to survive for months of freezing temperatures.

No State is Immune

As we know, fleas and ticks prefer warmer climates but do not vanish in low temperatures as their cocoons remain dormant during colder times. Considering the climatic conditions of every state, it is not unfair to say that every other state in the country is more or less populated with fleas and ticks; and some states are at mild risk of infestation, whereas some have moderate to severe risk of infestation.

There’s No Best Time to Start Flea & Tick Treatment

Since we’ve discovered that fleas and ticks are a year-round threat, there should be no pausing when it comes to giving your pets their required flea and tick treatment and/or preventives. If there’s a persistent threat of infestation, the protection must be uninterrupted too. So, a wise pet parent would continue with the flea and tick treatments throughout the year.

Every Season is Flea & Tick Season

To conclude, summer and spring are ideal for fleas and ticks. Although these blood-sucking parasites like warm weather, colder months of the year do not immune pets against the havoc created by these parasites. Therefore, it’s recommended to continue treating pets with flea and tick treatment all year around.
