Should you spray for special events?
If you’re hosting a special outdoor event like a wedding, graduation party, or backyard gathering, it’s smart to schedule mosquito and tick spraying ahead of time to help keep guests comfortable and bites at bay. Professional treatments should be applied 24 to 48 hours before the event to allow the product to dry and maximize effectiveness. Targeted spraying focuses on high-risk areas such as tall grass, wooded edges, dense shrubs, and under decks — all prime hiding spots for mosquitoes and ticks.
In addition to spraying, it’s a good idea to trim grass, clear standing water, and tidy up landscaping to reduce pest habitats. With proper preparation, you can enjoy your event without worrying about itchy bites or tick-related health risks. Learn more about how to prepare.
Tick-Borne Diseases to Watch for in Worcester County
Massachusetts is home to several tick species, with the black-legged tick (commonly called the deer tick) posing the greatest health risk due to its ability to transmit multiple diseases. Lyme disease is the most common tick-borne illness in the state, with thousands of cases reported each year. Early symptoms often include fever, fatigue, and a distinctive bull’s-eye rash, though not everyone develops the rash. If left untreated, Lyme disease can lead to more serious complications affecting the joints, heart, and nervous system.
In addition to Lyme disease, ticks in Massachusetts can carry other illnesses such as anaplasmosis, babesiosis, and Powassan virus, though these are less common. These diseases can cause flu-like symptoms, and in some cases, more severe health issues. The best defense is prevention: using tick repellents, performing regular tick checks after spending time outdoors, and treating yards to reduce tick habitats can all help lower the risk of tick-borne illnesses.
