As August arrives, most regions in the Northern Hemisphere enter the critical transition period from summer to autumn. With lingering high temperatures, highly active mosquitoes, and continuous hatching of residual parasite eggs in the environment, this month remains a vital node for annual parasite prevention and control. The WERVIC parasite control team reminds owners not to extend deworming intervals prematurely due to dropping temperatures, as overlapping parasite risks require standardized internal-external deworming as the core of pet health protection.

Pets face three major parasite threats in August. First, external parasites such as fleas and ticks remain in their active breeding period, keeping infection risk high in outdoor grasslands and wooded areas. Second, mosquito density stays at an elevated level, sustaining the transmission risk of heartworm, which causes severe cardiopulmonary damage once infected. Third, warm and humid conditions accelerate the development of intestinal parasite eggs, maintaining high infection rates of roundworms and hookworms. Many owners relax protection assuming parasites decrease in autumn, which easily leads to seasonal infections.
A broad-spectrum, long-lasting deworming formula is essential for scientific prevention. WERVIC Imidacloprid and Moxidectin Spot-on Solutions (separate formulas for dogs and cats) are recommended. The compound formula of imidacloprid and moxidectin eliminates external parasites including fleas, ticks and ear mites, controls intestinal nematodes such as roundworms and hookworms, and effectively prevents heartworm infection, delivering all-round protection in one dose. Apply the product strictly according to pet body weight, on the skin at the back of the neck, and avoid bathing within 48 hours after administration. Monthly use covers all parasite risks during the summer-autumn transition. Regular environmental disinfection to remove residual eggs will further reduce infection risk from the source.
