There are no toxic products labeled for geckos, lizards or any reptiles or amphibians, and given the highly beneficial nature of these creatures there is not likely to be any products for them any time soon.The reason they are on your property are because they can find food and proper habitat. Take away their food and they will forage somewhere else. Take away the conditions they need for hiding and they will seek refuge someplace else.
You really have two options here:
1.Exclusion. Total exclusion can be hard to achieve particularly around the roof-line where there are going to be gaps that would be very hard to close off, but there also could be some obvious flaws such as broken vent screens, holes around cables, pipes or wires, or gaps under doors. All of these can easily be closed with brush strips, caulking, copper mesh (Stuf-Fit), or some other suitable material. Exclusion is the best choice, because it is permanent, and eliminates or reduces the problem in the future too.
2.Outdoor habitat modification. In short, get rid of the reasons geckos are there in the first place. They are there because they are finding the food they need to survive (insects) and a place to harbor. If you can eliminate either of these essentials, you can get rid of the geckos. Spray a good residual insecticide such as Cyper WP around the outside of your home to help cut down on the number of insects the geckos are eating. If geckos cannot find enough food they will either move on or starve. Eliminate as much clutter and debris around the outside of your home as possible to eliminate the places geckos like to hide. Rake back mulch or rocks at least 6 inches from the structure.
If you need to get rid of the geckos that are already indoors the only options are catching them by hand or using glue boards placed in areas where the geckos travel.
Each jar of Cyper WP comes with a full product label attached to the the jar. If you take a close look, you will see that you can peel off the label and there is a direction booklet attached. Cyper WP does come with a scooper and you do use one or two level scoops per gallon. Most of the common pests require 1 scoop per gallon of water. If you are treating carpenter ants, carpenter bees, cockroaches, fire ants, scorpions, spiders, ticks or wasps, then you need to use 2 scoops per gallon of water.
Yes, Cyper WP is perfectly safe to apply around pets and/or children. When you are applying the product you should do exactly as you suggest, which is keep the pets inside or if applying inside in another room until the product dries. After it dries which is usually about 30 minutes, it is perfectly safe to allow pets entry back into the yard or living space.
Cyper WP will kill any type of ant that you physically spray it on, but the problem with most ants is that the colony is somewhere else. If you want to get rid of the problem for good you have to get rid of the colony, which is the source of the issue. We sell a Raspberry/ Caribbean Crazy Ant Kit that has been very popular for these crazy raspberry ants and it includes Termidor SC. Termidor SC does not kill the ants right away, but it allows them to walk over the barrier you apply around your home, and the ants end up taking the product back to the colony where it spreads like a plague. It works like a liquid bait. Residents of Texas have been very successful with this product.
Cyper WP can be used indoors and outdoors for spider control. When treating indoors be sure that all pets and other people are out of the application area and they can return as soon as the area is dry. The Cyper WP product label recommends 2 scoops of product per gallon of water, sprayed directly into cracks and crevices, under appliances, around door frames and window frames and in places where utilities (cables, pipes, wires) enter into the structure. We have recently added a spider control kit to our website that includes Cyper WP, Cobweb Eliminator and glue boards. Using Cobweb eliminator will help discourage spiders from forming webs on the surfaces that have been sprayed and the glue boards will help trap wandering spiders and help monitor problem areas.
Yes, this product is one of our best sellers for scorpions. Cyper WP comes with a scooper inside which you can use to mix one or two scoops with a gallon of water in your hand pump sprayer. For scorpions you need to pack a punch, so we recommend using 2 scoops per gallon of water. Apply around the foundation of the home outside once a month. This will keep a good residual present and you will see a huge difference with your scorpion issue. Even though this product packs a punch for scorpions, it is perfectly safe to have children and pets in the yard after the spray dries. It is only strong enough to kill smaller bugs and insects. Below is a great article on the control of scorpions.
