Product Description:

Don’t let uninvited insects invade your home and garden – usher them out the door with TERRO® Home Insect Killer.

This non-staining, odorless insect killer is effective against more than 65 different types of insects. Cockroaches, ants, spiders, silverfish, centipedes, flying insects, pantry pests, carpet beetles, ticks, lice and ornamental garden insects (just to name a few) don’t stand a chance against this long-lasting, ready-to-use insect killer.

The ready-to-use container with attached spray hose makes spraying a breeze. Just insert the sprayer hose-end into the snap-cap opening and set the sprayer nozzle to desired setting. Apply as a spot and crack and crevice treatment with the narrow spray setting; target broader areas with the wide spray setting.

Peace of Mind

If the sight of cockroaches scurrying around your kitchen is enough to ruin your day, relax and enjoy a little peace of mind with the long-lasting protection offered by TERRO® Home Insect Killer. After spraying, it continues to kill German Cockroaches up to 12 months.

If annoying flies are driving you crazy, don’t worry, we’ve got you covered - our insect killer continues killing flies up to 150 days after spraying.


Hide and Go Seek

Insects like to conceal themselves in their environment, whether indoors or outdoors. It’s your job to seek them out and eliminate them. Rest assured knowing you can use TERRO® Home Insect Killer anywhere insects are found.

Indoors, apply the insect killer as a spot and crack & crevice treatment to areas where insects crawl and hide. Common hiding places include areas around sinks, behind baseboards and around doors and windows.

Outdoors, you’ll need to seek out the places insects tend to hide. Check for nests that are hidden under steps, concrete, brickwork and similar areas. When you find a secret hiding spot, hold the sprayer at a slight downward angle 12 inches from the surface to be treated and spray on infested area. Spray enough insect killer to slightly moisten the surface. Be sure to also spray freely around ant trails and hills.

    Not sure.... By Worth A Try
    I bought the home insect killer over the Holidays after moving into a new apartment building and seeing a few roaches. My mom recommended TERRO and she doesn't have bugs, so I thought Id try it. The jury is still out. I have a one bedroom apartment and have sprayed weekly since Christmas yet I still see at least one roach each night. Some say that goes along with apartment living because they know how OCD I am about cleanliness. I'm just not sure why Ive used half the bottle and still see roaches. I'll keep trying and update in a couple of weeks.

    Product Works Great! By SpiderlessinCo
    Purchased Terro spray and spider / moth traps online after a little research...very easy to order, shipped the same day, very pleased with the service. The product itself really works....does not leave a smell or residue, but I found several dead spiders the following day, and have not seen any sign of spiders since. Terro is as good as my exterminator, if not better, at a fraction of the cost and very easy to use! I am very impressed and understand why the reviews i read beforehand were so positive....add this one to the list!

    Pests in house reduced to ZERO! By Nick2016
    My wife and I were somewhat concerned about moving. We spotted a live scorpion in the house two weeks after the move. Using a blacklight, we found at least a dozen scorpions in the back yard in a single night. Since then, I started using the TERRO aerosol spray from Walmart - sprayed around the outside of the house, by the vents, garage door, etc - wherever these little pests might find their way in. It worked great, and no stains!! So good, we went straight to TERRO and stocked up with four GALLONS to use on the perimeter of the yard, once after a rainfall (for good measure). Not just our house, but the ENTIRE back yard is now scorpion-free! I pitched a tent and camped out with the kids in the back yard a couple weeks ago. THANK YOU, TERRO!!

    HIGHLY RECOMMENDED!! We never paid for expensive pest control, and it's much cheaper to get TERRO by the gallon (instead of the aerosol alternative from the retailers).

    My go to home insect killer By Thomas
    I've tried other insect killers available at my local Home Depot and the Raid products. The Terro Home Insect killer is much better. I've started buying Terro products exclusively because they work better than anything else I've tried, and I've tried a ton of stuff. The quality of the Terro spray bottle is better than others but the real gem is the chemical formula which I find kills my roaches longer than any other product I've tried. I use this in conjunction with the Terro bait products to keep my ants and roaches at bay in the hot Florida weather.

    Non-toxic & Convenient By SHARON B
    Terro's Home Insect Killer really works -- and keeps on working even weeks after spraying. It's easy to use & affordable -- plus, it keeps your home as toxic-free as possible because it replaces having to hire an exterminator who uses all sorts of toxic chemicals. Just be careful when using it around pets.

    Ants Own My Home for 3 Years. By Knightmare
    Ants have owned my home, mostly the kitchen for the last 3 years, but this year they were like the Romans of old, they wanted the whole house. They ventured into my pantry room & started hauling off the cereals first, then the crackers and pretzels. When I noticed that the 5 lb. of sugar was moved to the end of the shelf I started worrying. The straw that broke the camel's back was when they got on my bed. I started wondering if my name was Gulliver. That's when I went online and ordered enough Terro products to take on the Northwest side of town. I put out outside bait, inside bait, liquid bait & sprayed along the baseboards with the insect spray. My most popular product to use was the liquid bait in conjunction with the granulated bait. I watched those little suckers lift some of that bait that a human couldn't possibly lift. I was amazed and overjoyed at the same time. The liquid bait was about like opening a beer joint in the dry side of town, everyone came. 24 hours a day they came and went and came again. This went on for 3 days and I didn't try to stop them, because I knew that they were going to carry a lot home to feed the Queen & anyone else that didn't want to get out in the weather. The 3rd day it was like the cops put out a DUI checkpoint, nary an ant in sight. I haven't seen an ant in over a week inside my house. It's now time to take the battle to them, I'm venturing outside to take on the Roman Empire. Right now I feel like a Barbarian.
