Reduce mosquito bites with EPA-registered repellent, protective clothing, window screens, weekly standing-water checks, and a plan for children and outdoor activities.
Mosquito-bite prevention works best as a layered plan. Repellent matters, but so do clothing, screens, standing-water checks, and preparation for the place and time you will be outdoors.
This guide explains how to prevent mosquito bites using current CDC and EPA guidance. It is written for everyday activities such as gardening, walking, outdoor work, community events, camping, and time on a porch or playground. No single step removes all risk, so combine the measures that fit your situation.
Different mosquito species are active at different times. Planning only for evening exposure can leave gaps. The CDC advises people to protect themselves because mosquitoes can bite day and night and can spread germs through their bites.
Before an outdoor activity, consider the setting rather than guessing from the clock. Shade, vegetation, standing water, recent rain, and local mosquito activity may affect exposure. If public-health officials issue local recommendations, follow those updates.

The CDC recommends an EPA-registered repellent with an active ingredient such as DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone. Look for an EPA registration number on the label and choose a product based on the activity, expected protection time, and who will use it.
Use the product exactly as directed. Apply only to exposed skin or clothing when the label allows it. Do not apply repellent under clothing, and reapply only as the label instructs. If sunscreen is also needed, the CDC says to apply sunscreen first and repellent second.
The EPA’s repellent search tool allows users to compare registered products by active ingredient and protection time. Registration does not mean every product is appropriate for every person or use, so read the entire label.
Adults should apply repellent for young children. Put the product on your own hands first, then apply it to the child’s face. Avoid children’s hands, eyes, mouth, cuts, and irritated skin. Dress children in clothing that covers arms and legs when practical, and use mosquito netting over strollers and baby carriers.
The CDC says not to use products containing oil of lemon eucalyptus or para-menthane-diol on children under 3 years old. Always follow age restrictions and other directions on the specific label.
If a child has a history of reactions, sensitive skin, or another health concern, ask a healthcare professional which options are appropriate. “Natural” does not automatically mean safer or effective.
Loose-fitting long sleeves, long pants, socks, and closed shoes can reduce exposed skin. Choose clothing appropriate for the temperature and activity so that bite prevention does not create a heat risk.
Some clothing and outdoor gear are sold pretreated with permethrin, and some products are labeled for treating gear. Follow the product directions carefully. The CDC specifically warns not to apply permethrin products directly to skin.
For group activities, include a short prevention note in advance so participants can decide what to bring. Do not promise a mosquito-free event. A safer message is that organizers are reducing avoidable exposure and sharing current protective guidance.
Repair holes in window and door screens and make sure doors close properly. Air conditioning can help keep spaces closed when it is available, but it is not accessible or affordable for every household. Screens, netting, and physical barriers remain useful alternatives.
When traveling or sleeping in a place without reliable screens, use a properly installed bed net appropriate for the setting. Keep doors closed when practical and avoid leaving containers of water indoors.
Mosquitoes can lay eggs in or near water. Once a week, check indoor and outdoor areas for containers that hold water. The CDC advises emptying and scrubbing, turning over, covering, or discarding items such as buckets, toys, flowerpot saucers, birdbaths, small pools, tires, and trash containers.
Assign zones if several people share a property or community space. One person might check the entrance and planters, another the play area, and another the waste and storage areas. Use gloves and avoid handling hazardous containers without appropriate support.
Standing-water control should respect property boundaries and local rules. Do not enter private property, drain protected habitat, or apply pesticides to water without authorization and label directions. Community groups can focus on education, cleanup of permitted containers, and reporting larger concerns to the appropriate local agency.
Organizers can include bite prevention in site selection, participant messages, and day-of checks. Choose spaces with maintained grounds when possible, identify shaded and seated areas, and make clear that participants may bring their preferred EPA-registered repellent.
For an accessible plan, provide the same information in more than one format, allow time for personal-care needs, and keep routes clear. UWP’s guide to making a community event accessible offers a broader planning checklist.
Groups interested in sharing plain-language prevention information can explore UWP’s Community Outreach and Get Involved pages. These links do not indicate a current mosquito-control service or event.
The CDC notes that the effectiveness of non-EPA-registered repellents, including some products marketed as natural, is not known. Scented plants, bracelets, phone apps, and home mixtures should not replace proven protection.
A useful decision rule is simple: verify the EPA registration number, read the label, and match the product to the user and activity. If a claim sounds absolute—such as “chemical-free,” “works for everyone,” or “guaranteed protection”—treat it cautiously.
UWP’s guide to reliable health information can help you evaluate prevention claims and identify the organization responsible for the advice.
Store products according to their labels and away from children. Check expiration and container condition periodically. Never transfer repellent into an unlabeled bottle.
Use several layers: an EPA-registered repellent, protective clothing, screens or netting, and regular standing-water checks. The best combination depends on the person, activity, climate, and setting.
The CDC lists DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, and 2-undecanone among active ingredients in EPA-registered repellents. Use the EPA search tool and product label to choose.
Clothing, screens, netting, and eliminating water-holding containers can reduce exposure, but they may not be enough in every setting. Public-health guidance recommends EPA-registered repellent as an important protective layer.
Use intact screens, close doors, use air conditioning if available, and consider a properly installed bed net where screens are absent or unreliable. Follow travel-health guidance for the destination.
Use only products and ages allowed by the label. Adults should apply repellent to young children, avoid hands and the face’s sensitive areas, and never use OLE or PMD products on children under 3, according to CDC guidance.
The CDC advises applying sunscreen first and insect repellent second. Reapply each product according to its own directions rather than assuming they share the same schedule.
The CDC recommends checking at least once a week and emptying, scrubbing, turning over, covering, or discarding water-holding items. More frequent checks may be useful after rain.
