Having a sandbox in your backyard can provide hours of entertainment for your children. However, bugs like ants, spiders, and flies can quickly invade the space and ruin the fun. Thankfully, there are several natural and safe options to deter pests while still allowing your kids to enjoy playing in the sand.

Use Diatomaceous Earth
One of the best ways to keep bugs out of a sandbox is by sprinkling diatomaceous earth (DE) around the perimeter. DE is a chalky powder made from fossilized algae. It is completely non-toxic for kids and pets, but acts like tiny shards of glass under an insect’s exoskeleton, causing them to dry out and die.
To use DE, simply wear a dust mask and gloves while sprinkling a light coating along the edges and just inside your sandbox. Reapply after heavy rains or every 2-4 weeks during peak bug seasons. The sharp DE will deter crawling insects from being able to access and lay eggs in the sand.
Try Natural Repellents
Certain strong smells can effectively repel insects looking to invade your kids’ sandbox. Try these natural repellents:
– Citronella oil – The aroma of citronella candles helps repel mosquitos, ants, roaches, and flies. Dab cotton balls with citronella and place them around the sandbox perimeter. Reapply the oil every few days.
– Lavender, peppermint, or eucalyptus oils – The strong scents of these essential oils naturally deter many insects. Mix 5-10 drops into a cup of water and pour into a spray bottle. Mist around the sandbox edges.
– Vinegar or garlic water – Vinegar’s acidity and garlic’s pungency disrupt bugs’ scent receptors. Mix either with water and spray onto areas bugs may access.
– Coffee grounds or dried peppermint leaves – Sprinkle these around the sand’s exterior to repel spiders, ants, and mosquitos using scent. Replace after rainfall.
Use Physical Barriers
Installing simple physical barriers can prevent crawling insects from being able to get into your sandbox:
– Clear vinyl sheeting – Attach a 1-2 ft wide strip of clear heavy duty vinyl around the outer walls of your sandbox. Bury a few inches of the sheet into the ground. The smooth surface deters bugs from crossing over into the sand.
– Petroleum jelly – Coat the upper inner walls with a thin layer of petroleum jelly. The slippery surface prevents insects from being able to climb over into the sandbox. Reapply after heavy rain.
– Duct tape – Wrap bands of upside-down duct tape, sticky side out, around sandbox legs and edges. The tape’s tackiness traps small bugs. Replace tape monthly.
– Sandbox lid – Make or purchase a tight-fitting lid for your sandbox when not in use. This deprives bugs of the opportunity to lay eggs in the sand.
– Mesh screen – Cover the top of your sandbox with a fine mesh screen when not in use. Look for fiberglass, nylon, or aluminum screen with openings smaller than 1/8″. The protective cover keeps bugs out while allowing airflow.
Introduce Natural Predators
Certain beneficial insects are natural predators that feast on troublesome sandbox pests:
– Ladybugs – These colorful beetles feed on aphids, mites, and other small insects. Attract them by planting flowers that small bugs like to eat, like allysum, yarrow, and dill.
– Green lacewings – The larvae of this insect devour soft-bodied bugs like caterpillars, aphids, thrips, and flies. Place lacewing eggs or larvae near your sandbox and they’ll hunt down prey.
– Dragonflies – Both the nymph and adult stages prey on mosquitos, flies and other flying insects. Install a small nearby pond to draw dragonflies to your yard.
– Spiders – Although spiders can also build webs in your sandbox, many kinds (like crab spiders and jumping spiders) will hunt nuisance insects. Avoid harming helpful spiders who take up residence nearby.
Keep the Sand Clean
Bugs are attracted to moist, dirty sand littered with food scraps and debris. Follow these tips:
– Stir and flatten the sand daily to prevent hills, piles, and nesting spots. Leveling allows you to spot eggs or insects.
– Sift through the top few inches weekly to remove food, droppings, rocks, sticks, and other clutter. These can attract pests and provide hiding spots.
– Sprinkle baking soda over the surface monthly then rake in gently. It absorbs moisture and deters bug egg-laying.
– Replace the top 2-3 inches of sand every 1-2 years. Old sand accumulates waste, eggs, and larvae over time.
– Avoid food, sugary drinks, or standing water in the sandbox. Promptly remove toys, dishes, or shovels when playtime is over.
Try Insecticides as a Last Resort
If non-toxic methods fail to keep your sandbox pest-free, insecticide dust or spray may be your best option:
– Diatomaceous earth dust containing pyrethrin insecticide can offer added bug-killing power while still being low-risk for children.
– Boric acid powder is another low-toxicity option that can be lightly sprinkled around the sandbox perimeter to kill ants, cockroaches, silverfish, and other insects. Keep away from kids and pets when applying.
– Look for an insecticide spray made from natural essential oils like peppermint, clove, or rosemary oil. Spot treat the upper edges and corners only, avoiding direct contact with the sand play surface.
When using chemical pest control methods:
– Follow all label precautions and keep kids away during application and until completely dry.
– Only apply insecticides directly to wall surfaces, not sand.
– Start with natural, least toxic solutions first before trying more potent commercial products.
Conclusion
Having to constantly shoo away bugs while your kids are playing can make your family’s sandbox far less fun. But you don’t have to resort to dousing the area in harsh chemicals. There are many safe, natural ways to deter insects without ruining your children’s playtime. Test out scent repellents, harmless diatomaceous earth dust, barriers to block pests, and introducing beneficial predators in your yard. With some simple prevention tactics, you can keep bothersome bugs at bay and enjoy nuisance-free sandbox play all season long.
