Cleaning and disinfecting surfaces is an important part of preventing the spread of COVID-19. Only disinfectants kill viruses, not cleaners or sanitizers; look for "disinfect" on the label. It's important to always follow the "contact time" listed on the label, which is the time the surface must stay wet with disinfectant to kill the virus. Check to see that you're following all instructions, including where the label says it can be used. Do not allow children to use any disinfectants, even wipes! Learn more in the expanded FAQ linked below.

Pesticides used outdoors may have risks to nearby people and animals. While each product has unique risks, steps can be taken to minimize the risk of exposure. First steps may include staying out of the area during and after the application. Moving sensitive items and keeping doors and windows shut may also help to minimize exposure. Please feel free to call us and talk to one of our Pesticide Specialists to discuss your situation at 800-858-7378.
Exposure to enough of any substance (water, pesticides, pain killers) can make a person or animal ill. The toxicity of different pesticide active ingredients can vary. Some are very low in toxicity and some are high. Whether high or low in toxicity, the health risks depend on your amount of exposure to the product.
Find toxicity information on ingredient fact sheets, learn more about understanding pesticide risks, and how to minimize risks. Please feel free to call us and talk to one of our Pesticide Specialists to discuss your situation at 800-858-7378.
Symptoms vary widely. Potential health effects depend on the pesticide and how a person was exposed. Reported symptoms from exposure to different ingredients may be found in our active ingredient fact sheets or by searching in health databases. Talk to your doctor for medical information.
Pesticides approved for organic production or ingredients like plant oils are sometimes low in toxicity. However, this is not always the case. Some of these products are just as toxic or even more toxic than similar synthetic pesticides.
Consider looking for the signal word "CAUTION" on a label to know it's a low-toxicity product. You may also consider looking for pesticides with certain qualified ingredients that are called minimum risk pesticides.
Consider reducing the need for pesticides by using a combination of methods for control. You may be able to receive free pest control advice from a Master Gardener or another local expert by calling your Cooperative Extension Service.
All pesticides have some level of toxicity and pose some risk during pregnancy. The risks can depend on the product, who will apply it, and where it will be applied. Call us to discuss your questions and find more detailed information below.
There are no quick answers that apply to every situation. However, you can get a good sense of the risk by gathering information from nearby pesticide users. In general, the risk from any pesticide depends on how toxic it is and how much contact you have (eating, breathing, touching).
If directions on a product label are unclear or if you have questions, consider calling the manufacturer of the product. If you cannot find the phone number for a company, call us for help at 800-858-7378.
A product label may not say what you are not allowed to do with it. Labels usually only list how you are allowed to use the product. If it isn't on the label, don't do it. In general, there are a few safe use practices you may wish to follow.
The breakdown of a chemical is measured by its half-life. Each ingredient will move differently in the environment. Pesticide ingredients vary in their potential to dissolve, vaporize, bind to soils, or enter groundwater.
If you have an herbicide, use the Herbicide Properties Tool to find how it might move in the environment.
Handle dirty clothes with gloves and keep them in a bag away from pets and children until they can be washed. Wash the clothing separately from family laundry to prevent cross-contamination. Find tips for wash cycles, drying, and detergents in the expanded FAQ below.
Do what you can to avoid spills and damaging containers during transport. Place products in the trunk of your car or as far away from passengers and pets as possible. Secure the load with ropes or straps. Avoid leaving products in extreme temperatures (hot or cold).
The two products are not identical. 'Food grade' products are not labeled for pest control and have not been evaluated for pest-control related risks. The amount of diatomaceous earth that can be used in food production may be much less than you would use in your home for pest control.
Food grade products don't tell you how much to use or what precautions to take (dust mask, etc.) while applying the product.
Mothballs contain high concentrations of insecticides designed to off-gas and kill fabric pests like moths. Mothballs should only be used in airtight containers that trap gas and prevent the fumes from entering living spaces. Inhaling the mothball fumes can cause health problems. The label will tell you exactly where and how a product is supposed to be used.
Cockroaches can enter a home in many ways. They may want shelter, food, or water. Keep the kitchen clean, repair plumbing leaks, and seal cracks and holes to keep cockroaches out.
Dealing with a flooded home can be complicated. Reduce the potential for mold by drying out the building as fast as possible. Plan on disinfecting or discarding everything that was wet.
Covering skin with loose, light-colored clothing and using mosquito repellents can reduce mosquito bites when outside. Consider using permethrin treated clothing. The CDC lists DEET, picaridin, IR3535, and oil of lemon eucalyptus as repellents that typically provide 'reasonably' longer-lasting protection.
Whether or not you need to treat for mosquitoes can depend on your situation. Learn about whether mosquitoes in your area carry diseases. Check if the community (vector control) is already spraying for mosquitoes. Consider what else you can do to keep mosquitoes away like removing standing water.
There are no EPA-approved sulfur products that can be burned to protect plants from pests. There are unknown risks with using an unevaluated product. Exposure to gas from burning sulfur can cause coughing, sore throat, and sometimes severe eye irritation.
Organic food is not necessarily pesticide-free. Food with a USDA organic symbol has been largely produced without man-made pesticides or other man-made products. Only organic pesticide ingredients can be used on foods that are certified organic, with very few exceptions.
Washing produce under running water is better than dunking it. You can scrub tougher skins with a clean brush or rub soft produce while holding them under running water. The Food and Drug Administration does not recommend using detergents or soaps.
Some weed killers can be used to prepare the soil before planting and some cannot. Check the product's label before applying. It may also list how long to wait before planting different types of vegetables.
The risks may be unknown. If contaminated compost is already in the veggie garden, there are a number of options. You may choose to plant your vegetables elsewhere, grow a cover crop of plants to dispose of later, or take steps to speed up the herbicide's breakdown. Or, you may choose to remove the contaminated soil altogether.
There are unknown risks with consuming food from plants that were accidentally treated with a pesticide. Often, we don't know how much of the product is on or in the food. Sometimes, a person may not even know what type of pesticide could be on the plants.
NPIC can help you understand the risks by discussing the toxicity of ingredients, their movement within a plant, and their breakdown in the environment. Call us at 800-858-7378 for more information.
Yes. All rodenticides can be toxic to people and animals when eaten. Be aware that pets could be poisoned from eating poisoned prey. Think about how a pet might be exposed to the product based on where it is stored or applied. Bait stations may not be 100% pet-proof.
Baits can have ingredients that pets might find tasty. Keep pets away from rodent baits during storage and during use. Consider covering baited holes with sod and a heavier item like wood or a brick so that pets cannot dig it up.
Pets tend to be curious. Remove pets and their toys from an area before treatment. Keep pets away from treated areas until a product has dried and the area has been well ventilated. The label may contain more instructions.
Adverse reactions associated with spot-on products are rare, but any flea and tick control product has some risks. They have the potential to be hazardous, especially if used incorrectly. Call us at 800-858-7378 to discuss any adverse reaction to pet products or other pesticides.
There is a variety of slug and snail baits available today. Baits may be attractive to dogs so take steps to reduce their access to a treated area or a stored product. Check the active ingredient on your product's label and read more about the toxicity of different ingredients in the expanded FAQ below.
