Soil Contamination from Mosquito Spray

Q: Over the years we have had a lawn and pest control service and used a mosquito spray around the house. Have the plants or soil been permanently contaminated?

A: I don’t believe there is any contamination. Most modern pesticides have a relatively short half-life (the time it takes for them to break down). If you have concerns about edible plants being affected, soap and water will usually remove pesticide residue.
