Designated exterminator,someone has to do it.

This sprayer is easy to use. The instructions were simple just follow the instructions and you too can save money without hiring a professional . Place chemical in tank fill with water to correct level screw the top and push the plunger handle as few times . The sprayer was inexpensive especially since I bought it on sale and is quite substantial. Sure I'd rather hire an exterminator however that's a rather expensive proposition .Just use safety precautions as you would using any tools. .Using gloves and eye protection is extremely beneficial. Walmart took care of the free shipping and it came as promised. Spring is here and I'm ready for a beautiful flower garden using my sprayer , hopefully with less bugs. Thank you Walmart. Sheldon

The best thing about the sprayer is the anti-clog system. It cost a few dollars more but worth it. I did get freaked out a little bit when I saw that it wasn't fully set up cuz I am in my 80s and don't like that stuff. My son did it for me and just 5 minutes. For some reason though, I seem to lose pressure and had to pump it again and again but I think I'm doing something wrong because it wasn't consistently that way. I like the size too because it was much easier to use than a really big one.

I had this brand sprayer and a 2 gallon form for over three years never had a problem with it, but now that I am watching my lifting and bending I've gone to the 1 gallon size which is perfect for me
