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.

Buena calidad
The best thing about Ortho Home Defense is its convenience. The electric sprayer works wonderfully and saves you the effort of using manual sprayers. It leaves no odor or stains, and it truly delivers on its promise: it keeps ants and spiders out of your house for months. Highly recommended for preventative home maintenance.

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.

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…
