Product Description:

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

The ready-to-use home insect killer spray can be applied as a spot, crack and crevice treatment with the narrow spray setting, or as a broader treatment with the wide spray setting.

Hide and Go Seek

Insects like to conceal themselves in their environment, whether indoors or outdoors, which is why we think you’ll like the fact that you can use TERRO® Home Insect Killer anywhere insects are found.

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

Outdoors, you’ll need to stake out the places insects tend to hide. Check for nests that are hidden under steps, concrete, brickwork and similar areas. Spray enough insect killer to slightly moisten the surface. Be sure to also spray freely around ant trails and hills where an entire army of ants is likely hiding out.

Peace of Mind

If the sight of cockroaches scurrying around your kitchen is enough to ruin your day, 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 — and, since roaches lay eggs, you’ll be reassured knowing that the insect killer you spray today will still be working when the eggs hatch weeks later.

If annoying flies are driving you crazy, we’ve got it covered — our insect killer continues killing flies up to 150 days after spraying.

    Works Great By rbarker1159

    I love all the Terro products. The bug spray works great. weeks later when you come across a dead bug you realize it's still working.

    DEAD, DEAD, DEAD By vsm0001

    I first bought this spray 3 or 4 years ago, one bottle. Each year I have to search and search my area to find it. I was pleasantly surprised that the product keeps on working days, weeks, even a few months after the first spray. I am actually surprised that others find it not to work, for I have had many, and I do mean many dead stink bugs in window seals, corners outside around my home. I was even ecstatic last year when the spray reached to the eves of my house! Needless to say Torro, I will gladly endorse this product. ps- weeks later after stink bugs swarmed...Asian lady bugs show up, did the trick with them as well!

    Disappointed By Judy

    I was very disappointed that I am still seeing occasional roach after two applications. It has consistency of water and also has no smell. I’m wondering what percentage water is in this product
