Patti I have no idea why I have never had any bugs. I do think my home temp and somethings I do before bringing in my plants help.
- I do not have my home over 68 degrees because I hate a hot house. I have steam heat and not forced air. They say forced air is dry air.
- I water very seldom. Never more than once a month. Because the house is cool the plants do not need a lot of water.
- I do not bring my plants in until the temps are in the 30s. It kills all those little summer bugs. I do not bring plants in as soon as it gets cool. All my plants can take 35 degrees. While the temps are in the 70s I hose the big plants and put the small plants in a bucket of water and soak them. Bugs will float to the top.
- Once all the plants are in for about a week or two every plant gets a squirt of Peroxide and water. In a gallon of water one table spoon of Peroxide in a gallon water poured in a squirt bottle.
