Roach infestations do not build up in a short period of time and they do not usually go away in a short period of time. Roach infestations can take several months to get rid of, though most folks see the infestation dramatically decline within the first couple weeks of treating. This is usually followed by a reappearance of the smaller roach nymphs (baby roaches). All of this is completely normal and expected. Some homes do require repeat applications of roach bait and insecticide sprays every two to four weeks to get rid of the remaining roaches. A barrier insecticide spray application around the exterior of the home will help stop new roaches from moving in. Indoor and outdoor sanitation is key to eliminating roaches. Be sure the trash is taken out every night and that all of the counters and floors are kept crumb free. Dry sinks and keep tooth brushes and sponges inside of plastic bags to eliminate sources for moisture. Outdoors, move trash cans and yard debris (leaf piles, mulch, wood piles) away from your home. Seal up as many cracks, gaps or holes on the exterior of your home to prevent roaches from entering. All of these steps will help you get rid of the roaches for good.

The Roach Control #2 would not be the best option for you because Demon WP cannot be used in a greenhouse. We would recommend using a Roach Control Kit. The Invict Gold and Gentrol Point Sources can be used inside greenhouses. The Gentrol Point Sources will be used to stop the roaches from reproducing which will take care of the small roaches you are seeing. Lizards and toads are not on the label so we would recommend contacting the manufacturers to make sure they will not harm these animals. If you are wanting to spray an insecticide around your greenhouse, we would recommend using Stryker Multi-Use Insecticide. It is not labeled to be used on any type of edibles but can be used on greenhouse plants. According to the label, you should not spray more than once a day.
Using a bellow hand duster to apply Diatomaceous Earth in wall voids, cracks and crevices where roaches like to hide will treat for roaches. Diatomaceous Earth needs to be reapplied frequently or when the infestation reappears. When treating for roaches, we recommed using one of our Roach Control Kits. THese kits contain the necessary products to do a full treatment for roaches. You can read about our Roach Control kits here. Our most popular Roach Control Kit is our Roach Control Kit #2. Please read below for details on this kit.
The Roach Control Kit #2 is perfect for roach control problems in homes and apartments. This professional kit includes 1 packet of Demon WP Insecticide (which makes 4 gallons of finished solution) for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get 4 x 30 gram tubes of Advion Roach Bait Gel--one of the best roach baits on the market. Advion can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, 20 Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. Demon WP must be applied with a 1 gallon pump sprayer.
Demon WP and Cy-Kick Aerosol will treat roaches but we do not recommend that these products be used as the sole treatment for this species of roaches. We recommend that you use our Roach Control Kit #1 in addition to a residual spray like Demon WP for indoor treatment of german roaches.
For around the door frames you can spray either the Demon WP or Suspend SC, the roaches can still be seen there but they will die after contacting the area that either product was applied to.

Roach Control Kit # 2 is labeled for German and American roaches. We would recommend using Advion Roach Bait Gel. It is labeled for Asian and German roaches, as well as various other types as well. You will use 3-5 spots per 10 linear feet for heavy infestations and 1-3 spots for a light to moderate infestion. We would still recommend the Gentrol Point Sources. They are a birth control for the roaches and will stop them from laying eggs. Please let us know if you have any additional questions.
