Organic Mosquito and Gnat Control in a Shaded New Jersey Backyard

A family in Marlton, NJ, battles mosquitoes and gnats under a large oak tree where kids play. Chemical broad‑spectrum sprays would harm children.

Integrated Organic Approach

1. Eliminate standing water — even dry containers that catch rain (Asian tiger mosquitoes lay eggs there).
2. Bti (Bacillus thuringiensis israelensis) wafers in birdbaths — kills larvae, safe for birds/pets.
3. Attract insect‑eating birds (swallows, kingbirds) with baths and nest boxes.
4. Dragonfly nymphs — natural mosquito predators; available from insectaries.
5. BG‑Sentinel trap with CO2 + lure — effective for Asian tiger mosquitoes (Biogents).
6. Contact NJ Mosquito Control — they have the nation's oldest program; tax‑funded help available.

Plant‑based repellents and citronella candles have minimal effect. Focus on breeding‑site reduction and biological controls.
