We do have two options that should work well for your situation. The first is the Bonide Mosquito Beater in a ready-to-spray bottle. It repels mosquitoes, gnats and flies in any outdoor area including patios. It is an all natural product so it's safe to use on your plants and safer for you and your family than chemical alternatives.
Here's a link to review the product online:Â

We also carry Cedarcide YardSafe Insect repellent in a ready-to-spray bottle. It also repels mosquitoes and other flying insect and is 100% organic. It can be used on vegetables and any other plants you might have, plus it can be used indoors if necessary.

With both of these products I can not guarantee what they will do to house paint. Your best bet with any product you purchase to battle the mosquitoes is to test it on a small section of painted area to see what effect it has. They are both natural oils so I don't believe they will cause damage, but oils can potentially make some paints run, so please do be careful and do a test.
Also, the websites that I've linked you to do sell these two products, but I would alert you to the fact that their shipping charges are rather high, so your best bet would be to simply visit any of our Sloat stores to get the best value. Plus our team members can continue this discussion with you in person if you like. If there is a particular Sloat store that you like to shop at, just let me know and I'll be sure that they have these choices in stock for you so that you do not waste a trip.
