IT WORKS VERY WELL - IF YOU USE IT CORRECTLY
This is a solid product. This is not designed for infestations or ant hills. It is a product designed to prevent entry of insects into your residence and eliminate individual insects that have entered. While this may help the odd case of colonized insects, it really is made for those solo runners that snuck in when you weren't looking. If you have an infestation or a mess, your insects are doing more than entering your house, they are living in it. Perhaps if it was sprayed around the house like the floors were being watering your floors it would work on infestations...but, PLEASE DON'T DO THAT, it wasn't designed for that use nor was that dosage tested for human/animal exposure. Consider calling an exterminator for infestations (100s+, colonies, groups of insects, etc.). And as for ant hills, either remove them, or buy poison for ant mounds. Are there ant hills in your home? That seems like a different problem. After you've taken care of cleaning things up, then protect your residence from the entry of new insects. You'll see this product is WONDERFUL FOR THE JOB. I've used it for years, one home in a very wooded, shaded area, one home in the south. Works like a charm...spraying as others have mentioned...seasonally. This product works by leaving a residue, so if what you spray it on (baseboard, perimeter of home covered in leaves in the fall, edge of home outside, etc.) is cleaned, blown away, excessively rained on...some or all of that residue will be removed...particularly overtime. Be aware of your specific situation and adjust your application frequency accordingly. IF YOU CREATE A BARRIER, THEY WILL NOT ENTER. (Read the label for all the insects covered...it's extensive.) 1. Clean up your outside and inside space a little of non-permanent items, pulling things from the perimeter (toys, anything that shouldn't be on the floor or ground basically). Eliminate debris and items in which insects hide, make webs, etc. 2. Spray the OUTSIDE perimeter and along the border of every door and window. 3. Spray the INSIDE perimeter, along the base boards, of your whole house (closets, pantries, bathrooms included). Then spray a barrier between rooms (around the door frame). Lastly, I understand the frustration that might occur if your wand or applicator never came. Exchange it with Amazon, try a spray bottle, etc. I've been using this with pets. Label says that IT MUST DRY BEFORE IT IS OK WITH PETS. Please remove them from the area while you apply. If you have a pet roach or tarantula I don't know what to tell you. All the best, and good luck with your application.

I wholeheartedly recommend.
Does a great job!! My exterminator just quit showing up and wouldn’t answer calls or texts. So I saw this product on Amazon and decided to try it. Arrived on time and I immediately sprayed my house as instructed. I haven’t seen a bug since. I think those exterminators weaken their product so as to come more often. I’ve already saved 2 spray jobs after 5 months and still no bugs. Great product. I still have over 75% in the jug left.

Worked great for flea problem!
I had a random flea problem and this seemed to help! It was really convenient to use. The sprayer was helpful in getting into the nitty gritty spots. It’s odorless (thankfully) it also has a lock, making it safe from leaks, and from pets and children. It’s a big size, so it will last.

Great for DIY bug control
Great product for DIY bug control. I have used this product for many years and I look for sale prices when I can get them. This works great for along exterior window sills and along perimeter of home. Works great for crickets and other bugs and some ants. Product can/should be mixed with water or another bug product if needed. Very little smell, light yellow in color depending on the ratio mixture used, so can be used interior under cabinets and areas around doors where bugs may try to enter the home. Does not kill wasps or hornets but is a deterrent especially when mixed with a strong mint scent.

This may have solved my ant problem
We enjoy a summer rental and ants seem to be a reoccurring problem each year but after two treatments, I haven’t seen a living ant in two weeks. The lesson is, continue to treat every week for two weeks then monthly and your problems are solved. Battery operated sprayer is a real plus with a directional nozzle. Highly recommended Update 7/20 As I was preparing for this week’s treatment, the sprayer stopped working and after some troubleshooting there was still no suction with plenty of battery power. I write to ortho and here’s their response; Be sure that the end of the hose is firmly attached to the cap. Push on it until a distinct “click” is heard. The “click” indicates that the hose is attached correctly. * If have a spout on the container cap that flips up, make sure it is fully flipped up so it is straight up and down and not at an angle. * If have a knob on the cap, make sure it is turned to the "ON" position. When fully in the "ON" position, you should feel the knob click into place and the arrow on the knob will point to the middle of "ON". * Make sure that the wand is open and locked into position. * Check that the nozzle at the end of the wand is turned to an open position. There are either 2 or 3 open positions and 1 or 2 off positions (depending on wand version). * There is a lock on the trigger. Make sure that the trigger lock is not in the locked position. * Occasionally, some crystallization can clog the sprayer. After disconnecting the red plug from the cap soak the spray tip/nozzle in warm soapy water. This may dislodge any crystallized matter. The sprayer tip can be readily pulled off and snapped back on after cleaning * If this is the first time you have used the wand, be sure that the plastic protection strip has been removed from the battery compartment. The batteries will not engage until the plastic strip has been removed. * Batteries have a shelf life that will last through approximately two 1.33 bottles. It is possible that the batteries need to be replaced. The unit holds either 3 or 4 Double-A (AA) batteries (depends on the wand version). Replace the old batteries with fresh ones to see if that fixes the spraying issue. * If the sprayer motor is running and all of the above troubleshooting has been completed, the sprayer may need to be re-primed. To re-prime, place the container above the wand (either holding it above or setting it on something) and spray for 30 seconds in an area where the product can safely be dispensed. All Good advice but none of that helped with my issue. I write to Amazon and they immediately offer a no fuss replacement. This is why I love Amazon- Excellent customer service and they will continue to have my business.

Have used this product before in the Caribbean. No roaches or the like for 5 years so I know it works. Pretty hefty price tag though for shipment to the UK when much lower price on the other side of the pond. But the heart wants what the heart wants…
