It is best to avoid using pesticides or insecticides, in your home, on your pets, or in the yard or garden during pregnancy. Especially avoid them during the first trimester. Even natural and organic products do not necessarily mean safer.
Significant exposure to pesticides is a concern for adults, children and particularly expectant mothers. Garden insects, fleas, mosquitoes, ants and cockroaches are just some of the reasons that women commonly spray pesticides around their home. Pesticides and insecticides contain chemicals that are used to attack the nervous system of the insects, and cause them to die.
During the first trimester of pregnancy, the nervous system is rapidly developing in your baby, so you definitely want to avoid any type of contact with pesticides during this time.
Are agricultural pesticides or insecticides safe during pregnancy?
Most studies point out that the greatest risk of exposure to pesticides is during the first three to eight weeks of the first trimester when the neural tube development is occurring. If you discover you are pregnant and you live near an agricultural area where pesticides are being used, it is advised to remove yourself to avoid exposure to these chemicals.
Annals of Oncology, Epidemiology, Toxicology and Applied Pharmacology, Journal of Neuroscience, Occupational Environmental Medicine, and the American Journal of Public Health are just some of the journals reporting associations between agricultural pesticides and birth defects, pregnancy complications and miscarriage.
Are domestic pesticides or insecticides safe during pregnancy?
The safest rule of thumb is that pregnant women should avoid pesticides whenever possible. The California Birth Defects Monitoring Program reports that three in four women are exposed to pesticides around the home.
They also observed that pregnant women exposed to household gardening pesticides had a 1.5 greater risks for oral clefts, neural tube defects, heart defects, and limb defects. Women living within 1/4 mile of agricultural crops had the same elevated risk for neural tube defects.
Both the Environmental Health Perspectives Journal (EHP) Volume 110, and the Journal of the National Cancer Institute report that children who are exposed to indoor and outdoor pesticides are at a higher risk of leukemia. EHP adds that the risk is increased during the first three months of pregnancy and when professional pest control services are used. Similarly, the Journal of Epidemiology Volume 12, reports that pesticides used around the home increases the likelihood of possible tumor development.
The Journal of Occupational and Environmental Medicin, Volume 54, reports that women exposed to ant and cockroach pesticides had a 70% increase in the likelihood of stillbirths due to congenital defects.
Women should avoid pesticides during pregnancy, particularly during the first trimester.
What about organic or natural pesticides during pregnancy?
Almost all toxins used in pesticides are compounds that are naturally present in plants. Although they sound healthier, the terms organic and natural are not synonyms for better or safer. All chemicals, including natural chemicals, have the potential to cause harm if they are not properly handled. Make sure you read the warning labels on all pesticide and insecticide packages before handling.
Helpful Information on Pesticide or Insecticide Use During Pregnancy:
Below is helpful information related to pesticide or insecticide use during pregnancy:
- Don't panic if you realize you have been exposed to a pesticide. Any real risk comes from long-term or intense exposure. If you just treated your dog for fleas and exposed yourself to a pesticide, the risks to your baby are small.
- The safest plan is to avoid using pesticides or insecticides in your home, on your pets, or in the garden during pregnancy. Especially avoid them during the first trimester when the neural tube and nervous system are being developed.
- If there must be treatment to your home, your pet, or your garden for pesticides, follow these guidelines for decreasing the likelihood of exposure:
- Have someone else apply the pesticides
- Leave the area for the amount of time indicated on the package
- Remove food, dishes, and utensils from the area before the pesticide is used
- Wash the area where food is normally prepared following any application of pesticides in the home
- Open the windows and allow the house to ventilate after the treatment is completed
- Wear protective clothing when gardening to prevent contact with plants that have pesticide on them
