mealy bugs

Can someone suggest something that really works to wipe out an mealy bug infestation? Malathion, Ortho Systemic, Triazicide, Ortho Bug-B-Gone all slow the infestation but not do away with it. The plants are tropical plants including orchids in a large sun room. Any suggestions? We're going broke buying insecticides.

After the initial application, you have to hit them again in a few days to a week to kill the newborns.
Have you tried rubbing alcohol? It's cheap and non-toxic.

We sprayed them every few days for months on end. There are too many plants to do with alcohol on a swab. Or do you mean spray them with alcohol?

I had a couple of plants with them. I used the cotton swab with metho, but I also used a bit of metho in the homemade white oil. And don't forget to spray it onto the soil as well. And repeat once a week for 4 weeks.
Another thing that you might be able to try, is to rub off as many as you can with your fingers. It will just help to lower the numbers a bit. Do this before each and every treatment. If you've got kids, I'm sure they'd love to help.
Another, is to use a strong blast of water (shower or hose) to blast them off first.
Hope that helps

Thanks Jen. These are a large collection in a sun room that is part of the house. There's no way to shut it off from the living quarters so must be careful what is sprayed. Taking this many plants outside in the chill one by one to hose them off would be more than a chore, it would be a real burden with my arthritis. What a job that would be. Today I saw the geraniums have budworm but I couldn't locate any by eye. I saw the droppings and chewed leaves. Another plant has spider mites. It's getting overwhelming. I took the plants with mites and budworms outside and sprayed them with a strong spray of 3 different insecticides. The smell was horrendous and it was cold but above freezing. I brought them in before the temperature plummeted. What I really need is something effective I can spray them with indoors.
Spraying water in the sunroom isn't an option. Also oil sprays can damage the wainscoting and wallpaper so they are not an option in the winter. All these plants were hosed off and sprayed before I brought them in last October.

Thank you but I don't think my family would appreciate if I brought more bugs into the house. This also appears to be a control for outdoor mealy bug infestations.

g'day mindful,
over here the ants generally bring the mealies in, so first in that case the ants need to be moved on before treatment of the bugs will be effective.
you could make your own white oil spray and use that (recipe on our page) apply after the heat of the day 2 or more applications may be needed.
if the bugs get onto the roots of the plant then you may have to destroy the plant.
snipped With peace and brightest of blessings,

Thank you. Will check it out. I'm getting desperate since we have a lot of plants in the sun room. I don't want to lose them all.
