### Is it Safe to Use DEET-Based Insect Repellents During Pregnancy? Ticks can transmit several diseases with a single bite, the most severe being Lyme disease, which can affect your spine, joints, nervous system, and heart. If you get Lyme disease while pregnant, it can also affect your unborn baby. Here’s what you need to know to stay safe: Many insect repellents contain strong chemicals that harm insects' nervous systems. Since a baby’s nervous system grows rapidly during the first trimester, some experts suggest avoiding bug sprays during this time. It’s also unclear how these chemicals affect the rest of the pregnancy, as many haven’t been studied for birth defects. DEET is a common chemical in tick repellents. Some studies show that DEET doesn’t increase the risk of birth defects, but more research is needed. Therefore, it might be wise to avoid DEET products. However, if you spend a lot of time outdoors in tick-prone areas, consult your doctor. They may determine that the benefits of using a small amount of DEET outweigh the risks of contracting a tick-borne illness like Lyme disease. Some products contain natural oils known to repel ticks, such as eucalyptus and citronella. The effects of these ingredients on pregnancy haven’t been studied either. If used according to package directions, they’re probably safe but may not offer strong protection and can wear off quickly. Note that taking these oils as supplements won’t repel ticks and could harm your baby. To stay tick-free, consider these simple strategies: - Wear long sleeves and pants when outdoors. - Stay on clear paths and avoid tall grass. - Check your body and clothes for ticks after being outside. Remember, a tick bite doesn’t guarantee Lyme disease. Removing a tick within 24 hours reduces your chances of getting sick. If you show early signs of Lyme disease, like a rash or flu-like symptoms, see your doctor immediately.
