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.

    TERRO® Home Insect Killer is rated 4.9 out of 5 by 34.
    Rated 4 out of 5 by from Not sure.... 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.

    Rated 5 out of 5 by from Product Works Great! 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!

    Rated 5 out of 5 by from Pests in house reduced to ZERO! 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).

    Rated 5 out of 5 by from My go to home insect killer 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.

    I have ants everywhere in my Florida home, I also have pet birds, is this spray safe for them to breath? Would I spray the entire inside & outside of my house with this spray? Tks ~

    This product can be confidently used in the home around people and pets. Spray around doors, windows, and other places where ants enter the house. Spray outdoors onto ant trails and hills. We recommend keeping children and pets out of the treated area until the product has dried.

    How often do I need to apply, for silverfish indoors? 

    Asked by: theautumnleaves
    When treating for silverfish, we recommend applying the product to the areas infested by these pests. Check the areas every 4 weeks and retreat if insect activity continues. Directly spraying the product on an insect will give immediate results.
