Call an exterminator, preferably a small mom&pop shop and not a big Orkin or Terminex or whatever, and have them come and and do a mosquito treatment. They’ll spray a chemical on the outside of your house, under the leaves of your trees/bushes, etc. Then they’ll spray inside, but just the corners for other bugs. You’ll need to keep your dog out of the chemical inside for about 10-20 minutes, and out of the chemical outside for probably an hour. After that it’s dry and non-toxic to mammals but will get soaked up by insects. Be sure to double check that with the exterminator, times vary depending on the chemical used.
Good treatments should last a solid 2-3 months, which ought to be enough to get you through the worst of mosquito season, unless you’re in Florida or something.
