Each 32 fl. oz. bottle mixes into 4 gallons of spray, providing up to 12 months of indoor protection on non-porous surfaces.

## Description

Ortho® Home Defense® Insect Killer for Indoor & Perimeter Concentrate kills common household bugs including the mosquito, cockroach, fly, ant, spider, wasp, cherry fruit fly, beetle, flea, tick, stink bug, and silverfish. This insect killer has been specifically formulated for indoor and outdoor use both as a preventative treatment and for when you see evidence of insect activity. Use with confidence in kitchens, bathrooms, basements, along doors and windows, on patios and decks, in garages, and along the perimeter of the foundation. For long-lasting, residual control, leave the applied spray undisturbed. With this long-lasting spray, you'll have up to 12 months of protection from ants, roaches, and spiders (indoors on non-porous surfaces). Retreatment of this quick drying spray is recommended once per season (or every three months) in outdoor settings. Each 32 oz. container of Ortho® Home Defense® Insect Killer for Indoor & Perimeter Concentrate makes up to 4 gallons of non-staining and odor free bug killer which can be applied using a tank sprayer.

Review: 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.
Review: Pleased with purchase

## Questions & Answers

**Q: Does it kill bed bugs too?**
A: Steam cleaning kills bed bugs. This spray is good for preventing a reoccurring problem, after you kill the live ones and eggs with high-heat steam.

**Q: Is this safe round infanst and pets**
A: Just to be on the safe side, I would make sure pets and infants aren't in the treated area, when actually being treated.  However, I haven't seen any side effects in my dog.

**Q: What is the difference between ortho home defense indoor and perimeter2 and the ortho home defense max?**
A: I was about to write a review as I use both products, and saw this question and decided to give a valid answer as others may want to know.

They are basically the same product as mentioned, however they have different uses and different chemicals/amounts for that purpose. While ortho is good inside the home, MAX is better used outside the home (and inside) but in order to benefit from it you need to spray it on hard surface next to your house, tile, concrete doors, windows ect. That is why I am lining my home with 2-3 ft of crushed white rock or concrete because in order to be effective the surface needs to be 1) solid for the MAX to stick to and 2) smooth and at least 12IN for the spiders/pests to cross. But as I stated I use both Ortho inside and MAX around the outside and the MAX does provide 12 months of protection while the Ortho I believe is only 3 months.

**Q: Is this for inside of the home only, in other words is this for outside and inside and if only one do i need a different spray for the other?**
A: I use both inside and outside.  It is clear and does not stain or stink.  Inside I only do exterior doors and window sills although you can do baseboards as well. Hope that helps.
