Spider mites are slow moving, normally light in colour with distinct dark spots on either side of their body. They feed on many soft or fleshy leaved plants, causing speckling and discolouration.

At high densities they produce silk that can cover the plant. Mites will overwinter in conservatories, greenhouses or bamboo canes. If damage occurred last year, introduce the predators early. 

The tiny red coloured spider mites are plant-feeding mites and feared pests on several crops all over the world. In dry, warm weather a spider mite population can grow very rapidly.

Species

The most common species are two spotted spider mite (Tetranychus urticae) and the carmine spider mite (Tetranychus cinnabarinus).

Spider Mite control with Phytoseiulus 

Where RSM is already established, use Phytoseiulus, a fast-moving predatory mite. Temperature needs to be consistently over 20°C. Repeat applications every 2-3 weeks in hot weather.

Regular introductions between June and August for effective control.

Available to order between: 1st May - 1st October

Description and life cycle

The female deposits round eggs of about 0.14 mm on the underside of the leaf. Out of the egg a colourless larva with 6 legs hatches and immediately starts feeding. Subsequently, the larva develops into a protonymph, a deutonymph and an adult stage.

The nymphs are light to dark green and have 2 clearly developed body spots. The colour of the adults can vary from yellow-brown to red-brown, depending of the crop on which they occur.

Both males and females have 2 large dark body spots. The development stages are separated by a resting stage, during which the mite settles immobile on the leaf.

Once the mite has become adult, it takes another 0.5 to 3 days before the female starts laying eggs.

The total development time takes 7 days at 30°C (86°F), 17 days at 20°C (68°F) and 36 days at 15°C (59°F). The female lays her eggs for 10 days (at 35°C or 95°F) and up to 40 days (at 15°C or 59°F). At 20°C (68°F) she lays about 40 eggs in total, but under optimal circumstances this can mount up to 100.

Especially during dry and warm weather spider mites can reproduce very rapidly. In autumn, when temperature and photoperiod drop, fertilised females enter diapauses. Such females turn orange-red. They hide in all kinds of cracks in the greenhouse, to appear again early in the following season when circumstances improve.

It worked on all size of cans
Eh pretty good for the whopping 3 weeks I had it. Came home one day and it was broken. It still operated. As in all functions were there but it wouldn't latch onto cans anymore. I think one of my adult kids dropped it. Honestly surprised motor still operated after it's drop.

Didn't work out for me after a few uses.
Broke after only like 5 uses...not worth the money. Doesn't stay sharp nor does it auto-clamp onto cans after such uses. Thought it worked only to find out it didn't cut the can and left little metal shavings from just kinda "scratching" the can and I ended up getting a splinter. Thought it was low on battery and fully charged only for it to keep not cutting the can. Trashed it just gonna buy a regular stand up from walmart or something.

So simple to use, I'm amazed
Color: Black
Wonderfully helpful. Description is accurate, shipping was quick. I saw a few poor comments, but I have none so far! The can opener has opened cans of several sizes, from tomato paste to large cans of tomatoes; soup cans to strangely shaped. It's opened 30 or so already without loss of power. It's a little noisy, but about equal to that of a stand up opener. It fits in my drawer, which is less deep than most kitchen drawers. Most of all, it's beyond easy to use for arthritic hands. The ONLY CHALLENGE I have is that it sometimes fails to stop when it should. MANUFACTURER: if you read this and have advice, please share. At this point, I'd say this is a great value for the money.
