Our Verdict

     Not many bug sprays get everything right, but Ortho’s Bug B Gon manages a spectacular A. With its 6-month runtime, easy application, cheap price, and high effectiveness against bugs, you’d be hard-pressed to find a better one on the market. 

     Having to spray yourself with down with a mosquito repellent every time you want to go outside gets annoying. So, instead of counting on a repellent that will last a few hours for your mosquito problem, why not use bug spray that will last months?

     If you’re not sure what bug sprays you should be looking for, don’t worry. Right here, you can find all the information you need about Ortho Bug B Gon Lawns and Gardens, the spray promising to solve your bug problem.

Product Overview

     Ortho’s Bug B Gon promises 6 months of protection against, according to them, 235 insects, including mosquitoes, ticks, spiders, ants and more. However, black widow, brown recluse, and hobo spiders bypass the 6-month promise, so you may need to re-apply sooner if you deal with those specific spiders.

     They also claim 5,300 square feet is the treatable lawn/garden size for Bug B Gon, which edges out Cutter’s 5,000 by just a little.

     Ortho states that Bug B Gon works immediately after spraying, so there’s no need to “wait it out” to find out if you’re spray works.

     Just like Cutter’s spray, Bug B Gon is safe for ornamental use. Whether bugs have infested your lawn or your flowerbed, Bug B Gone remains a solid solution. However, just like with most sprays, you shouldn’t use it inside the home.

How it Works

     Once you notice an uptick of bugs in your lawn or garden, it’s time to spray them down with Bug B Gon. It will start killing the bugs immediately, so don’t worry about any stragglers getting into your house.

     While you only need to re-apply the spray when necessary, Ortho recommends waiting at least 7 days between each application, as not to harm the environment in any way.


     Ortho sells Bug B Gon through its website, the spray costing $11.49 for 32oz. That’s a fair deal if you ask me; it’s only a fair bit cheaper than Cutter’s. 

     Considering the potency and effectiveness of this spray, I’m pleasantly surprised it’s not more expensive.

Does it Work?

     I’m glad to tell you that Ortho’s Bug B Gon works wonders. Sure, a few reviewers complain about it not being effective, but considering the other 90% of people who love the product, I’m willing to bet on Ortho.

     While it’s not natural like Eco Defense’s spray, it keeps your lawn/garden healthy while offering high-end protection—all for $11.49.

     If you’re looking to cover an area bigger than 5,300 square feet, this isn’t the product for you. If you’re not, I—and many others—recommend it.


     I will give out 3 scores, these scores being

  • Efficiency/Effectiveness (40%)
  • Ease of Use (25%)
  • Safety (35%)

Overall (Weighted grade)

     This system ensures that the less important aspects of the product don’t weigh down the product too much. So, without further ado, let’s jump into the scores.

Efficiency/Effectiveness = 10/10

     Bug B Gon, without a doubt, is one of the best bug sprays on the market right now. With its huge roster of targeted insects, mixed with the 6-month effective time, there are not that many products that beat it.

     While it’s not the cheapest spray around, I think Ortho priced this fairly. $11.49 is a drop in the bucket compared to the sanity you’ll regain once the mosquitoes start leaving you alone. Overall, I think the price is great.

Ease of Use = 9/10

    While using bug spray requires more work than a simple handheld repellent does, Ortho mixes the solution for you and gives you the pump; all you need to do is hook it up to your hose and spray. Nothing much to say here except it’s pretty simple and only needs to be reapplied when necessary.

Safety = 9/10

     Despite not using natural ingredients, Ortho created a bug spray that’s simultaneously healthy for the environment and you/your family/your pets. However, you need to be careful about your pets getting near your lawn or garden before the spray dries.
